TiiK pre^jent work is designeil to meet tlie want, which has \o\\*^ ])een felt, of a descriptive account of the lUrd.s of North America, with notices of tlieir geograpliical distribution, liabits, methods of nesting, cliaracter of eggs, their popuhir nomenclature, and other ])oints connected witli their life history. For many years past the only systematic treatises l)earing upon this sub- ject have been "The American Ornithology" of Alexander Wilson, tinislied bv that autlior in 1814, and brought down to the date of 1827 by CJeorire Ord ; the "Ornithological Biography" of Audubon, bearing date of 18;>8, with a second edition, " liirds of America," embmcing a little more of detail, and comi»leted in 1844; and "A Manual of the Ornithology of the United States and Canada," by Xuttall, of which a first edition was published in 181)2 and a second in 1840. Since then no work relating to American Ornitludogy, of a biographical nature, has been presented to the public, with the exception of some of limited extent, such as those of Oiraud, on the "Birds of Long Island," in 1844; De Kay's "Birds of Xew York," 1844; Samuels's "Orni- thology and Oology of Xew England," 1868, and a few others ; together with (|uite a nundier of minor papers on the birds of particular localities, of greater or less moment, chiefly published in periodicals and the Proceedings of Societies. The reports of many of the government exploring ])arties also contain valuable data, especially those of Dr. Xewl terry. Dr. Heermanu, Dr. J. O. Oooper, Dr. Suckley, Dr. Kennerly, and others. More recently (in 1870) Professor Whitney, Chief of the (Jeological Survey of California, lias pul)lished a very important volume on the ornithology of the entire west coast of Xorth America, written by Dr. J. G. Cooper, and containing nmch original detail in reference to the habits of the western spe- cies. This is In' far the most valuable contribution to the biograjjhy of American birds that has ap]K^ared since the time of Audubon, and, with its typogi'aphical beauty and numerous and excellent illustrations, all on wood and many of them colored, constitutes one of the most noteworthy publica- tions in American Zoidogy. Up to the time of the appearance of the work of Audubon, nearly all that was known of the sreat re^jion of the United States west of tlie Missouri liiver was the result of the journey of Lev.is and Clark up liie Missouri and 40292 yj PREFACE. across to tin* Pacitie- Coast, fiinl that t>t' John Iv. Townsend and Mr. Xuttall, l»oth of wlioiii made suim* cMllc'ctiniis and l»r(m,u;lit luick iiuticL's of the t'dun- trv, which, how c' or, lliev were uuahle to exjdore to any ^reat extent. The entire region of Texas, New Mexico, Cohaado, Arizona, Nevada, and Cali- fornia was unvisited, as also a ^reat portion of territory north of the United States boundary, including liritish ('(dunibia and Alaska. A work hv SirJolm Richardson, forming a volume in his series of " Fauna lioreali-Aniericana, ' in reference to the ornitludogy of the region covered by the Ihulson liay Company's operations, was published in 1831, and has been much used by Mr. Audubon, l»ut embraces little or nothing of the great Ijreeding-urounds of the water birds in the neighborhood of the Great Slave and P>ear hikes, the Upi)er Yukon, and the shores of the Arctic coast. It will thus be seen that a third of a century has elapsed since any at- tempt has been made to present a systematic history of the birds of North America. The object of the i)resent work is to give, in as concise a form as possible, an account of what is known of the birds, not onlv of the United States, but of the whole region of North America north of the boiindary-liiie of Mexico, including (Jreenland, on the one side, and Alaska with its islands on the other. The published materials for such a history are so copious that it is a matter of surjaise that they have not been sooner utilized, consisting, as they do, of numer«»us scattered biographies and reports of many government expe- ditions and i)rivate exi»lorations. Hut the most productive source has been the great amount of manuscript contained in the archives of the Smithsonian Institution in tlie form of correspondence, elaborate reports, and the field- notes of collectors and travellers, the use of which, for the present work, has been liberally allowed by Professo" Henry. P>y far the most important of these consist of notes made by the late Ifobert Kennicott in British America, and received from him and other gentlemen in the Hudson Bay Territory, Avho were brought into intimate relationship with the Smithsonian Institu- tion through Mr. Kennicott's efforts. Among them may be mentioned more es])ecially ^Ir. K. ^lacFarlane, Mr. B. li. Boss, Mr. James Lockhart, Mr. Liwrence Clark, ^Ir. Strachan Jones, and others, whose names Avill appear in the course of the work. The especial value of the communications re- ceived from these gentlemen lies in the fact that they resided for a long time in a region to which a large proportion of the mpaciiMis and water birds of North America resort during the summer for incubation, and wdiicli imtil recently has been sealed to explorers. Etpially serviceable has been the information received from the region of the Yukon Biver and Alaska generaBy, including the Aleutian Islands, as supplied by ^lessrs. Bobert Kenn.cott, \Villiam H. DaB, Henry M. Bannister, Hemy AV. Elliott, and others. It should be understood that the remarks as to the absence of general works on American Ornithology, since the time of Audubon, ai)ply only to the life I'KHKACK. yJJ Iiistorv (if the species, as, in 18r)S, one nf tlie iiutliois of tlie ])reseiit work juililisht'il ;i sysli'inatic iiceuunt <>f tlie liinls of Nnitli Anieriea, loiirstituliiiLj N'ol.

Nearly all the drawings of the full-length figures of birds eontaint'd in the ^vork were made directly on the wood, by Mr. Edwin L. Shej)pard, of Phila- deli»hia, from original sketches taken from nature; while the heads were exe- cuted for the most jiart by Mr. Henry W. Elliott and Mr. IJidgway.

INTRODUCTION. The class of Birds (Airs), as represented in the present a^^e of tlie world, is composed of very many species, closely related anions tliem:^elvcs and distin'nii^hed bv numerous characters common to all. Fones peculiarly cond)ined, (1) the proximal tarsal bones coalescing with the adjoining tibia, and (2) the distal tarsal coalescing with three (second, third, and fourth) meta- tarsals (the first metatarsal being free), and forming the so-ealled tarso- metatarsus ; dermal appendages developed as feathers : oviparous, tlie eggs being fertilized within the body, excluded with an oval, calcareous shell, and ^ W«' art' iii(lrl»t('(l to Pn)ft*ssor Tlu'odon' X.

Tlie character- istics liave Iteeii gi\en more fully in order to i)ermit a comjtarison between tlie memhers of the class and tliose of the mammals and rejitiles. The class is without exception the most homogeneous in the animal kingdom; and among the living forms less ditferences are ohservahle than hetween the re]»re- sentatives of many natural orders among other classes. JUit still the dill'er- ences hetween them and the other existing forms are sullicient. perhajts, to autliori/e the distinction of the grou}) as a class, and such rank has always been allowed excel ttinn" hv "la' recent naturalist, lUit if we further coinj)are the characters of the class, it becomes evident that those shared in common with the reptiles are much more numerous than those shared with the mammals. In this resjtect the vit'ws of natural- ists have chaniivd within recent vears. Formerlv the two character- istics shared with the mammals — tlu' (piadrilocular heart and warm bhKxl — were deemed evidences of the close atlinity of the two groups, and they were conse«iueiitly cond)ined as a section of the vertebnites, under tlie name of Warm-l>ltiles as members of a common groujt, separated on the one hand from the mammals and on the other fruts, in lii< " Kt V to Xoitli Aiuciiiiiii Ilinls,"' «jjiv<>s an alil<' ami «'xt"n«lttl aititiis of liii-, anttiiy" (X. iSdM), " On lli<- Caipii^ and Tarsus of Uinls,"' is of niu.h seientilir value. - Cams anil Cerstaeeker (llainlliueli der Zoologie, 18ri8, 191) j.re-ent the following definition of Innls as a i lass : — Aves. Skin covered wholly or in jiart with feathers. Anterior pair of liinhs, eonverted into winu^s ,i:<-nerally used in Hi<,dit : sonietinies rudimentary. Oeeiput with a sinle ven- tricle.

Nor is the class of birds as now limited confined to the single order of Mhich only we have living representatives. In fossil forms we have, if the dilferences assumed l)e confirmed, types of two distinct orders, one being rej)resented by the genus Air]uropteri/.r and another by the genera IcJitlu/oniis and Aimtoraiii of Marsh. The first has been named Snvrura' by Hieckel ; the second Lliflnfornitlnilrs by ^larsh. (.V>m})elled thus to (piestion the existence of any groups of ordinal value among recent birds, we ])roceed now to examine the grounds upon whieh natu- ral subdivisions should be based. The prominent features in the classification of the class until recently have been the divisions into groups distinguished i>y their adaptation for different modes of life ; that is, whether aerial or for progression on land, for wading or for swimming ; or, again, into Land and \Vat(;r l>irds. Such groups have a certain value as simidy artificial combi- nations, l>ut we m\ist not be considered as thereby committing ourselves to such a system as a natural one. The time has scarcely amved to justify any system of classification hitherto proposed, and we can only have a sure foundation after an exhaust- ive study of the osteology, as well as the neurology and splanchnology, of the various members. Enough, however, has already been done to convince us that the subdivision of the class into Land and Water Birds does not express xiv NORTH AMERICAX BIRDS. the true relations of the members embraced under those lieads. Enough has also been adduced to enable us to .«,touj) many forms into families and somewhat more coni2»rehensive groups, detinable l>y osteologieal and other characters. Sucli are the Chamdrimoiplue, ( ecomorpha*, Alectoromorpha?, I'terucLnnorphiu, Peristeromorphie, Comcomorphie, C'ypselomorpha', Celeo- morjjhu', Ai'tomorphie, and several othei-s. But it is very douljtful wliether the true clew to the attinities of the groups thus determined has been found in the relations of tlie vomer and contiguous bones. The families, too, have beeji probably, in a number of cases, especially for the passerine birds, too much circumscribed. The progress of systematic ornitliology, however, has been so I'apid witliin tlie last few years, that we may ha allowed to hope that in a second edition of this work the means may l)e furnislied for a strictly scientific classification and se(pience of the families. (T. N. G.) A primary division of recent birds may be made by separation of the {(() Batitcv, or struthious birds and their allies, — in which the sternum has no keel, is developed from lateral paired centres of ossification, and in which there are numerous other structural peculiarities of high taxonomic import, — from the (/>) Carinata., including all remaining ]>irds cf the present geologic epocli. Other primary divisions, such as that into Alt rices and Pracoccs of Bonaparte, or the corresponding yet somewhat modified and improved Pi^Uopaah'.'i and PtiJopaides of Sundevall, are ojien to the serious objections that they ignore tlie profound distinctions l»etween struthious and other birds, require too numerous exceptions, cannot be primarily determined by examination of adult specimens, and are based upon physiological considera- tions not necessarily co-ordinate with actual physical structure. In tlie following sclieme, without attempting to indicate positive taxo- nomic rank, and without committing myself finally, I present a number of liigher groups into which Carinate birds may be divided, capable of ap- proximately exact definition, and apparently of a])proximately equivalent taxonomic value. Points of the arrangement are freelv drawn from the writings of various authors, as will be perceived by those competent to judge without special references. I am particularly indebted, hcnvever, to the late admirable and liighly inqiortant work of Professor Sundevall,^ from which very many characters are directly borrowed. The arrangement, in effect, is a modification of that adopted l)y me in the " Key to North Ameri- can Birds,'' upon considerations similar to those herewith implied. The njain points of difference are non-recognifion of three leading groups of aerial, terrestrial, and natatorial birds, — groups without morphological l)asis, resting simply uj)on teletdogical modification ; a general depreciation of the taxonomic value of the several groups, conformably with the considerations presented in the preceding pages of this work ; abolishing of the group Oi'dllatvres ; and recognition of a primary group Sphemf^ci?

Family TURDIDiE. — The Thrushes. The Tiir(lidn\ with the Scwirolida^ and Clnclidcr, form a group closely related, hy coininon characters, and appreciably diflerent from tlie other Oxn'ncs with slender l>ills and specially insectivorous habits, having, like them, ten primaries (the first much shorter than the second, but nearly always ap]»reciable), and tlie nostrils uncovered. The great family of SnlriroJ'uhr, with similar characters of the bill, never present more than nine primaries. The most striking of these common characters is seen in the deeply cleft toes, of which the outer is united V»y tlie basal joint alone to tlie middle toe, while the inner is separated almost to the very base of its first joint.^ The frontal feathers extend, with rare exceptions, to the very nostrils. The bill is elongated and subulate, moderately slender, and usually notched at tip ; the culmeii moderately curved from the base, and the mouth well provided with bristles, except in a few cases. Usually the scutellic covering the front and sides of the tarsus are fused into one continuous plate, or else scarcely appreciable, except on the inner edge onlv ; in the ^Fockini; Thrushes thev are, however, distinctly marked. The lateral toes are nearly ecpial, the outer rather the longer. With these as some of the principal characteristics, they may be distinguished from each other as follows : — XoTE. — In tlie prosont work the lencrth of tlio tail i« mcaenrfd from the coccyx, in«iears, however, to be no lii^amentous adhesion. The basal joint of the outer toe is entiifly adher«'nt, and a membrane extends from nearly the basal half of the second joint to the distal end of the fii-st ji»int of the mi«hlle toe. "When this connecting membrane becomes diied the division of the toes api>ears consid»;ral)ly f,'reater. "Wlu'u the toes are all extended in line with the tarsus, the hind claw stretches a little lieyond the lateml and scarcely reaches the base of the middle claw. Tlii^ plates at the upper surface of the basal joints of tlie toes are quadrangular and opposite each other. ir'O'- .„. BRAINY 2 NORTH AMKHTrAX BTUDS. A* Nostrils oval. Loral and frontal foathers with bristly points, or intcrsprrsod with bristles ; rictus with lonjrer or sliortor bristles. Sazicolidse. Winjrs very long; and much pointed, reaching beyond the middle of the siiort surious priniary very short, the second quill lonp-r than the fom-th. In the el<)serimary sometinn'S half the Imgth of second quill ; the second (piill shorter than the fourth. In the closed wing the outer secondary reaches three fourths or more the length of longest primary. B« Nostrils linear, in lower edge of nasal membrane. Loral and frontal feathers soft and downy, and no bristles or bristly points whatever about the mouth. Cinclidse. Body very short and broad. Wings short, rounded, and concave. The American Si/Ini(I(r are in some respects very closely related to the Sa,ri(oli(fa\ but may be distinj^uished by their nmcli smaller size, mure slender and de[)ressed bill, more strongly bristled rictus, etc. ; on whicli account they are more strictly " Hy -catchers," taking their prey in great part on the wing. Of the three families, the Turdida- contain a great variety of forms, and exhibit widely difl'erent characters, rendering it exceedingly ditficult to arrange them in any systematic or regular scMiuence, or to accurately define their boundaries. In the Birds of North America, the Mocking Tlirushes were placed .among the Wrens, on account of the distinct tarsal scutelhe, and otlier cliaracters. We are now, however, inclined to believe, with Dr. Sclater, that their place is with the recognized Tvrdida; and, among other reasons, on the ground of their more deeply cleft toes, and greater extension forward of frontal feathers. The i'ollowing synoi)sis of the Nortli American forms will serve tlie })urpose c^f determining the genera, even if these are not armnged or combined in a strictly natural manner. A. Turdinse. — Tarsus covered anteriorly with a continuous plate without scales. Wings decidedly longer than the tail, w^hich is nearly even. Bill con- siderably shorter than the heaf bill, and about twice length of gonys.' Tarsi stouter, longer than nuddle to<' and claw. Tail feathers widening slightly from base to near ti[t, giving a parallel-sided or slightly fan-shaped appt'arance to the tail. Tin Mniiiiitf diller, as already mentioned, in the scutellate tarsi : more rounded wings, etc. — S. F B. Subfamily TURDIN^. There are several American genera of Turdlncc not found north of ^lexico as yet, althougli it is not impossible that one of these {Cathnrns) may liereafter be detected within the limits of the United States. The species of CathtiruH reseml>le the North American wood-thrushes {Hylocichla) ; but the spurious or first jaimar}^ quill is longer (from one half to one tliird the second ecies, with Turdus mus- tclinus, Gm., at the head as type, which are closelv connected on tlie one side with CatharuA, by their lengthened tarsi, and with Turdus by the shape of the wing. The bills are shorter, more dei>ressed, and broader at base than in typi- cal Turdus, so much so that the species have fre([uently been de- scribed under Muscicapa. It is not at tdl improbable that naturalists may ultimately conclude to consider the group as of generic rank. In this group there appears to be five well-marked forms or "species." They are, mustclinus, Gm., 'palhisi, Cabau., fusccsccns, Steph., swainsoni. Tardus mustelinus. TUKD1D.E — THE TIIUUSIIES. Caban., and alvirr, IJaiid. The first-immcMl is totally unlike the R.^t, which are nioic tdosely related in ai>pearanee. In studvini,^ carefully a very large series of specimens of all the species, the l'on(nvini4 facts become evident : — 1. In autumn and winter the "olive" coh)r of the plumage assumes a browner cast than at ot^er seasons ; this variation, however, is the same in all the sjiecies (and varieties), so that in autunin and winter the several species dilfer from each other as nuich as they do in spring and summer. Of these five species, two only {palhisi and siraiHsoni) inhabit the whole breadth of the continent ; and they, in the three ?\uinal rnninces over which they ex- tend, are moditied into "races" or "va- rieties" characteristic of each region. The first of these species, as the paJIcd var. jiiillasi, extends westward to the liocky Mountains, and migrates in winter into the South ; specimens are very nuich browner in the winter than in spring ; but in the liocky ^lountain region is a laruer, <;raver race, the var. ainltihoni. This, in its migmtions, extends along the central mountain region through ^lexico to (ruatemala; sj)ecimens from the northern and southern extremes of this range are identical in all the specific characters ; but the southern specimens, being in the fall and winter dress, are brcjwner in color than northern ones (spring birds) ; an autumnal example from Cantonment Ikirgwyn, X. M., is as l>rown as any Central American specimen. Along the IVicific Province, from Kodiak to Western ^lexico, and occasionally stra^nlinu: eastward toward the Itockv Mountain svstem, there is the var. nanus, a race shmlln- than tlie var. pallasi, and with much the same colors as var. ojidahoni, though the rufous of the tail is deeper than in either of the other forms. In this race, as in the others, there is no ditierence in size between si)ecimens liom north and south extremes of its distribution, because the breeding-] dace is in the Xorth, all Southern specimens being winter sojourners from their Xorthern birthplace. The T. sicaiiisoni is found in abundance westward to the western limit of the liocky ^lountain system ; in the latter region specimens at all seasons have the olive of a clearer, more greenish shade than in any P^asterii examples; this clearer tint is analogous with that of the liocky ^lountain form oi iKiUasi {aiuUihoni). In precisely the same region inhabited by the pallasi var. nanus the sirainsoal also has a reju'esentafive form, — the var. if sf I' /at us. This resembles in pattern the var. swainsom) but the olive above is decidedly more rufescent, — much as in liocky ^b)uiitain specimens of Turilus ustulatus. g NOKTIl AMEiaCAN JUiiDS.

The remaining sj>ecies — ituis/cfinns, fits(rsrrn>i, and fdicia- — extend no farther west than the Ilockv Mountains ; the first and last only toward their eastern base, while the second Ijreeds abundantly as far as the eastern limit of the (Jreat Basin. The 7\ fa sr ('.sans, from the Itocky ^Fountains, is considerably darker in color alM)\e, while the specks on the thn)at and jugular are sparser or more obsolete than in Ejustern birds. In T. nnusttlinKs, the only two Western specimens in the collection (Mount Carroll, Ills., and Fort PieiTe) have the rump of a clearer grayish than specimens from the Atlantic Coast ; in all other respt^cts, however, they appear to be identical. Some Mexican specimens, being in winter jdumage, have the breast more butfy than Northern (spring or summer) examjdes, and the rufous of the head, etc. is somewhat brighter. In alkicv, no difl'erence is observed between Kastern and Western birds; the reason is, probaldy, that the breeding-ground of all is in one province, though their migrations may extend over two. There is, however, a marked difl'erence between the spring and autumn plumage ; the clear grayish of the former being replaced, in the latter, by a snufly brown, or sepia tint, — this especially noticeable on wings and tail.

So far as I am aware it is uukiiowii, or very mre, in the States of Vermont, New Hampshire, and Elaine. It makes its a]>p(^'arance early in A])ril in the Middle States, hut in Xew England not until four or five weeks later, appearing aljoiit tlie loth of May. Their migrations in fall are more irregular, being aj»j)arently determined by the abundance of their food. At times thev depart as early as the tirst of Sej^tember, but sometimes not until the last of October, It winters ill Central America, where it is quite abundant at that season. The favorite localities of the AVood Thrush are the borders of dense thickets, or low dami> Indlows shaded by large trees. Yet its habits are by no means so retiring, or its nature po timid, as these jdaces of resort would lead us to infer. A small grove in Iioxbury, now a part of r>oston, in close proximity to a dwelling-house, was for many years the favorite resort of these birds, where several pairs nested and reared their young, rarelv even leaving their nests, which were mostly in low bushes, whollv unmindfid of tlie curious children who were their frequent visitors. The same fearless familiarity was observed at ^Mount Auburn, then tirst used as a public cemetery. IJut in the latter instance the nest was always placed high up on a branch of some spreae such a recluse as many describe it. In one case a pair built their ne.'it within the limits of a thickly peopled \illage, where there were but few trees, and a scanty undergrowth.

Tliis species is one of tlie eommon liinls of Xew Enfjland, {ind is probiil)ly al)uiuljuit in certain localities tlironghout all the couni.y east of the Iiocky Mountains, as far to the north as the oOth parallel, and possibly as far as the wooded country extends. Mr. M.aynard did not meet with it in Xorthern New Hampshire. Mr. Wni. G. Winton obtained its nest and eggs at Halifax, X. S. ; ^Ir. Boardman found them also on the (Julf of St. Lawrence, and at St. Steplien's, N. B. ; Mr. Couper at Quebec ; ^Ir. Krieghoff at Tliree llivers, Canada ; Donald Gunn at Selkirk and Ited liiver ; and ^Ir. Kumlien and Dr. Hoy in Wisconsin. Mr. Mcllwraith also gives it as connnon at Hamilton, West Canada. It breeds as far south as Pennsylvania, and as far to the west as Utah, and occurs, in tlie breeding season, throughout Maine, New Brunswick, Xova Scotia, and Canada. Mr. Ilidgway found tliis thrush very abundant among the thickets in the valleys of the Provo, Wel)er, and Bear rivei's, in Utah, and very character- istic of those portions o*' the country. It arrives in Massachusetts early in May, usually with the first blossoms of the |)ear, ranging from the "jtli to the 2(lth. It is strictly of woodland habits, found almost entirely among clumps of trees, and obtaining its food from among their branches, or on the ground among the faUen leaves. It moves south from the lOth to the 2r)th of September, rarely remaining till the first week in October. It is timid, distrustful, and retiring ; delighting in shady ravines, the edges of thick close wooils, and occasionally the more retired parts of gardens; where, if mmiolested, it will frequent the same locality year after year. The song of this tlirush is ipiaint, but not unmusical ; variable in its character, changing from a ])rolonged and monotonous whistle to (piick and almost shrill notes at the close. Their melody is not unfrequently prolonged until , Birds X. Am. IS.'.S, 217, plate 81, i. 2. — Ib. Rt-vicw Am. Birds, I, 1864, 21. —Corns, Pr. Ac. N. Sc. Aug. 1861, 217 (I^ibnidor). — In. Catal.

Tins species, tii-st described in the ninth volume of the Pacific Kailroad Surveys, beai-s so strong a resemblance to the Olive-backed Thrush {T. swainsoui), that its value as a species has often been disputed. It was first met with in Illinois. Since then numerous specimens have Ijeen ob- tained from the District of Columbia, from Labr.idor, and the lower Mackenzie IJiver. In the latter regions it Wiis found breeding abundantly. It was also found in large numbers on the Anderson IJiver, but was rare on the Yukon, as well as at Great Slave Lake, occurring there oidy as a bird of passage to or from more northern breeding-grounds. In regard to its general habits but little is known. Dr. Coues, who found it in L'lbnidor, breeding abundantly, s})eaks of meeting with a family of these birds in a deep an<' thickly wooded ravine. The young were just about to fly. The parents evinced the greatest anxiety for the safety of their brood, endeavoring to lead him from their vicinity by fluttering from bush to bush, constantly uttering a melancholy phcrgh, in low whistling tone. He mentions that all he saw uttered precisely the same note, and were very timid, darting into the most impenetrable thickets. This thrush is a regular visitant to ^lassachusetts, both in its spring and in its fall migration. It arrives from alx)ut the first to the middle of ^lay, and apparently remains about a week. It passes south about the first of October. Occasionally it appears and is present in Massachusetts at the same time with the Tnrdus svainsotii. From this species I hold it to be unquestionably distinct, and in this opinion I am confirmed by the observa- tions of two very careful and reliable ornithologists, Mr. William Brewster of Cambridge, one of our most promising young naturalists, and Mr. George O. Welch of Lynn, whose experience and observations in the field are unsurpassed. They inform me that there are observable between these two forms certain well-marked and constant differences, that never faD. to indicate their distinctness with even greater precision than the constant though less marked ditierences in their i)lumage. The Turdns alicia' comes a few days the earlier, and is often in full song when the T. sicainsoni is silent. The song of the former is not only totally different from that of the latter, but also from that of all our other Wood Thrushes. It most resembles the song of T. pallasi, but differe in l)eing its exact inverse, for whereas the latter begins with its lowest notes and proceeds on an ascending scale, the former begins with its highest, and concludes with its low^est note. The song of the T. swain- TUKDID.E — THE THiiUSHES. 13 soni, on the other hand, exhibits much less variation in the scale, all the notes being of nearly the same altitude. * I am also informed that while the T. sirainsoni is far from being a timid species, but may be easily approached, and while it seems almost invariably to prefer the edges of the pine woods, and is rarely observed in open grounds or among the bare deciduous trees, tlie habits of the T. alicice are the exact reverse in these respects. It is not to l)e founds in similar situations, but almost always freciuents copses of hard wood, searching for its food among their fallen leaves. It is extremely timid and dithcult to approach. As it stands or as it moves upon the ground, it has a peculiar erectness of bearing which at once indicates its true specific character so unmistakably tliat any one once familiar with its appearance can never mistake it for T. sivaimoni nor for any other bird. The nests measure about 4 inches in diameter and 2 J in height. The cavity is 2 inches deep, and its diameter 2 J inches. They are unusually compact for the nest of a thrush, and are composed chiefly cf an elalxjrate interweaving of fine sedges, leaves, stems of tlie more delicate Eqiiisdacccc, dry grasses, strips of fine bark, and decayed leaves, the whole intermingled with the paniculated inflorescence of grasses'. There is little or no lining other than these materials. These nests were all found, with but few exceptions, on the branches of low trees, from tw^o to seven feet from the ground. In a few exceptional cases the nests were built on the ground. Occiisionally nests of tliis species are found constructed with the base and sides of solid mud, as with the common Kobin {Turdm migrator im). In these, as also in some other cases, their nests are usually found on or near tlie ground. So far as I am aware neither its occasional position on the ground, nor its mud frames, are peculiarities ever noticeable in nests of T. swainsoiii. The eggs were usually four in number. Their color is either a deep green tint, or green slightly tinged with blue ; and they are marked wdth spots of russet and yellow ish-brow^n, varying both in size and frecpiency. Their mean length is .92 of an inch, and their mean breadth .64. The maximum length is .94 and the minimum .88 of an inch. There is apparently a constant variation from the eggs of the T. swahisoni ; those of the alicice having a more distinctly blue groun(i color. The nests are also quite different in their appearance and style of structure. The Hj/pnum mosses, so marked a feature in the nests of T. swairisoni, as also in those of T. iistulatus, are wholly wanting in tliose of T. alicice. This bird and the robin are the only species of our thrushes that cross the Arctic Circle to any distance, or reach the shore of tlie Arctic Ocean. It occurs from Labrador, all round the American coast, to the Aleutian Islands, everywhere bearing its specific character as indicated above. It is extremely abundant on and near the Arctic coast, Ijetween the mouth of 14 NORTH AMERIC.VN BIRDS. tlie I^fackeiizie Eiver ami the (Vjppenniiie, more than 200 specimens (mostly with their ej^^gs) having been sent thence to the Smitlisonian Institution hy Mr. MacFarlane. In all this number there was not a single bird that had any approach to the characters of 1\ swainsoni, as just given. From the Slave Lake region, on the other hand, T. swainsoni was received in nearly the same abundance, and unmixed during the breeding season with T. alicia'. Turdus swainsoni, Cabams.

The Olive-backed Thrush, or " Swamp Kobin," has very nearly the same habitat during the breeding season as that of the kindred species with which it was so long confounded. Although Wilson seems to have found the nest and eggs among the high lands of Xorthern Georgia, it is yet a somewhat more northern species. It does not breed so far south as Massachusetts, or if so, the cases must l)e exceptional and very rare, nor even in Western Maine, where the "Ground Swamp Robin" {T. pailasi) is quite abundant. It only becomes common in the neighborhood of Calais. TURDID^ — THE THRUSHES. 15 AT It is, howTver, most widely distributed over nearly the entin^ continent, l.reedini,' from latitude 44° to high Arctic regions. It winters in Guate- mala and southward as far as Ecuador and Brazil. In its habits tliis thrush is noticeably different from the T palloai, l)ein nuu'h more arboreal, frequenting thick woods ; mrely seen, except during its mi«a'ations, in open ground, and seeking its food more among the branches of the trees. ^Ir. liidgwav found this species very abundant among the Wahsatch ^NFountains, where it was one of the most characteristic sununer birds of that region. It was breeding plentifully in the canons, where its song (!(>uhl be lieard almost continually. It inhabited an intermediate position between T. audnhoni and T. fusccscem, delighting most in the shrubbery along the streams of the canons and passes, leaving to the T. amJiihoni the secluded ravines of the pine regions higher up, and to the T. fnmacens the willow thickets of the river valleys. He did not meet with it farther west tluin the East Humboldt Mountains. The song, in his opinion, resembles that of the Wood Thrush {T. mmtcUnus) in modulations; but tlie notes want the power, while they possess a finer and more silvery tone. The song of this species has a certain resemblance to that of T. pnllad, being yet quite distinct, and the differences readily recognized by a familiar ear. It is more prolonged; the notes are more equal and rise witli more regularity and more gradually, are richer, and each note is more coiuplete in itself. Its song of lamentation when rol)bed of its young is full of inde- scribable pathos and beauty, liaunting one who has once heard it long after. When driven from the nest, the female always flies to a short distance and conceals herself ; making no complaints, and offering no resistance. These birds, in a single instance, have been known to reach Eastern Massachusetts early in April, in an unusually early season, bnt they generally pass north a few weeks later. They make no prolonged stay, and are with us rarely more than three or four days. Their return in the fall appears to be, at times, by a more inland route. They are then not so numerous near the coast, but occasionally are abundant. Their nests in Nova Scotia, wherever observed, were among the thick woods, on horizontal branches of a forest-tree, usually about five feet from the ground. Those observed in the Arctic regions by Mr. Kennicott were frequently not more than two feet from the ground. The nests average about four inches in diameter and two in height, the cavity being three inches wide by about one and a half deep. They are more elaborately and neatly constructed than those of any other of our thrushes, except perhmts of T. ustitlafvji. Conspicuous among the materials are the Hijpnnm mosses, which by their dark fibrous masses give a very distinctive character to these nests, and distinguish them from all except those of the T. mtuJatus, which they resemble. Besides these materials are found fine sedges, leaves, stems of equisetaceous plants, red glossy vegetable 16 NOKTII aMKRICAN BIRDS. fibres, the flowering stems of the Cladonia mosses, lichens, fine strips of bark, etc. The eggs, which are four or five in number, exhibit noticeable variations in size, shape, and shades of coloring, bearing some resemblance to those of T. ustulatm and to the eggs asserted to be those of T. nanus, but are sufficiently distinct, and are still more so from those of T. alicicc. They range in length from .83 to .94, with a mean of .88, their mean breadth is .66, the maximum .69, and the minimum .63. Their ground color is usually bluisli-green, sometimes liglit blue with hardly a tinge of green, and the spots are of a yellowish-brown, or russet -brown, or a mixture of both colore, more or less confluent, with marked variations in this resjiect.

Tliis well-marked race is to l)e compared with sirainsoni, not with fi(scesc€)is, as has generally been done ; the latter, except in shade of colors, it scarcely resembles at all ; still greater evidence that such is its aflinity is that the T. ustulatus builds its nest on a tree, and lays a spotted eg'^, like swainsoni, while fuscescens nests on or near the ground, perhaps never in a tree, and lays a plain blue e^^g. The song of the present bird is also scarcely distinguishable from that of swainsoni. Upon the whole, we see no reason why this should not be considered as a Pacific Province form of the Turdus swainsoni; at least it becomes necessary to do so, after I'eferring to T. pallasi, as geographical races, the T. auduhoni and T. nanus. Habits. So far as we are aware, this thrush has a very limited distribu- tion, being mainly restricted to the Pacific coast region from California to Alaska in the breeding season, though migrating southward in winter to Guatemala. Dr. Kennerly found it in great abundance breeding at Chilo- weyuck Depot, July 3, 1859. Dr. Cooper also found it one of the most abundant of the summer residents in Washington Territory, arriving there •rrRDID-E — TIIK THRISIIK.^. 17 in Mav and remaining until tlie l>ej;innin,i; of SeptemKu-. Tiiree spcciinens ol' this thrush were obtained at Sitka, hy Mr. liisehotl". Mr. liid".;\vay met with only a single specimen east of the Sierra Nevada, though on that range lie found it an abundant summer bird. In its gener.d aj)j)earance it has a marked resemblance to Wilson's Thrush (T.fttscfsrfu.'i), but its ha])its and notes, as Mell as its nest and eggs, clearly ]>oiut its nearer atlinity to Swainson's Thrush (7' amtiusoni), its song l)eing scarcely different from that « f the latter spn-ies. Like this species, it fre- tiuents the thickets or brushwood along the mountain streams, and, except just after its arrival, it is not at all shy. In crossing the Sierra Nevada in Julv, 18G7, Mr. liidgway first met with this species. He describes it as an exipiisite songster. At one of the canips, at an altitude of about r),()()() feet, they were found unusually plentiful. He speaks of their song as consisting of "ethereal warblings, — outbursts of wild meh)dy." " Altliough its carols were heard everywhere in the depth of the ravine, scarcely one of the little musicians could be seen." "The song of this thrush," he adds, "though })0ssessing all the wild, solemn melody of that of the Wood Thrush {1\ miistGlinm) is weaker, but of a much finer or more silvery tone, and more methodical delivery. It is much like that of the T. sivaiusoni, but in the qualities menticuied is even superior." Dr Coo})er found its nests with eggs about the middle of »Tune. These were most usually built on a small horizontal branch, and were very strongly constructed of twigs, grasses, roots, and leaves, usually covered on the outside entirely with the bright green Hi/pnutn }^ :)sses peculiar to that region, wdiich in the damp climate near the coast continue to grow in that position, and form large masses. The nund>er of eggs is usually five. Dr. C'ooper states that these thrushes sing most in the early morning and in the evening, when numbers may be heard answering one another on all sides. They do not affect the darkest tliickets so much as the Hermit Thrush, but are often seen feeding in the gfirdens in the oi>en sunshine. Dr. Suckley, who found them (juite abundant in the neighborhood of Fort Steilacoom, on the edge of the forest, and in swam])y land, describes the song as a low, soft, sad, and lively whistle, confined to one note, and repeateil at regular intervals. Mr. Nuttall, the first to describe this form, speaks of it as shy and retiring, and as in the habit of gathering insects from the ground. His ear, so quick to appreciate the characteristics of the songs of birds, which showed a close resemblance between the notes of this bird and that of Wilson's Thrush {T. /I'sresiTUJi), enabled him to detect very distinct and easily recognizable differences. It is nnich more inten-upted and is not so prolonged. The warble of this bird he describes as resembling irit-icit t'vi/lla, and wit-wit, t'viUia-t'villia. His call when surprised was wit-wit. All the nests of this sj^ecies that have fallen under my observation are large, compact, strongly constructed, and neat. They measure alMuit 5 inches in their external diameter, with a depth externally of 3 ; the cavity 3 18 iNORTII AMERICAN IJIHDS. is comparfitively sluillow, Lfiii^ rnri'ly 2 inches in depth. The external portions are constructed almost entirely of Hifi>niim mosses, matted to- gether and sparingly interwoven with dry leaves and fine fibrous roots, and are lined with finer materials of the same kind. Tliese nests most nearly resemble in their material and in their i)0.sition those of »S\vaiuson's Thrush. Mr. Hepburn found these birds very abundant about Victoria. It does not usually breed there Ixjfore the last of May, though in one exceptional instance he found a nest with young birds on the 24th of that montli. The eggs vary in size and shaiH3, ranging from .77 to .9-4 in length, and from .()."> to .09 in breadth. They also vary in their ground color and in the tints of the spots and markings. The ground color is light green or light blue, and the markings are variously yellowish-browu and lilac, or dark brown and slate. Mr. Gmyson found this thrush very abundant in the month of January, in tlie thickest of the woods, in the islands of tlie Three Marias, on the Pacific coast of Mexico. They were very timid and shy, more so than any bird that he saw on those islands. It fre, 205. — Baird, Binls N. Am. 1858, 212. — Ib. \li\. Am. B. 1864, 14. — Sclateh, P. Z. 8. 18.09, 325 ??. — Ib.

It has since been obtained abundantly on the Pacific slope, and Mr. Kidgway procured a specimen as far east as the East Humboldt Mountains, which he considers its eastern limit. In its habits it is said to be, like T. palhm, almost exclusively terrestrial. Dr. Heermann mentions finding it abundant in California, and breeding among tlie stunted oaks covering the sand-hills of San Francisco. Dr. Coues found it in Arizona, but speaks of it as rare and migratory, occurring chiefly in spring and autumn, and as a shy and retiring species. Dr. Cooper, in his Peport on the liirds of California, describes it as shy and timid, pre- ferring dark and sliady thickets, feeding chiefly on the ground, running rapidly, and searching for insects among the leaves. Xear San Diego they began to sing about the 2r)th of April. The song, consisting of a few low ringing notes, resembles that of Wilson's Thrush {T./i'scesceiis), and also that of T. ndulntn^, but is not so loud. Their note of alarm is a loud and ringing cliiri), rei)eated and answered by others at a long distance. At Santa Cruz, on tl:e first of June, Dr. Cooper met with several of their nests, which, though prol>ably erroneously, he supposed to belong to the Dwarf Hermit Thrush. They were all built in thickets under the shade of cottonwood-trees. Each nest was about five feet from the ground, and all contained eggs, from two to four in number, in differing stages of incuba- tion. The nests were built of dry leaves, roots, fibres, grasses, and bark, TT"RI)ID,K-THK TIIIirsHES. 21 without uny imul, uiid were lined witli decayed leaves. Tlieir hei.i,dit and ex- ternal diameter measured 4 inches. Tlie diameter of the cavity was 2\ inches and tlie dejith '2\. The e,i,'«;s measured .!M> hy ."0 of an inch. Tliey are of a ]ude bluish-green, sjHickled with cinnamon-brown, chietly at the larger end. The nest, supposed to be of this sjxjcies, su^jplieil by Dr. Cooper, is large for the bird; constructed of a l)ase loosely made up of mosses, lichens, and coarse fibres of jdants. It is a strong and compact structure of matted leaves, put together when in a moist and decaying comUtion ; witli these tliere are interwoven roots, twigs, and strong til)res, surrounding the nest witli a stout band and strengthening the rim. In fact, it corresi)onds so well — as do the eggs also — with those of T. Ufitidatii>i, that it is extremely proba- ble that they really l)elong to that species. The only observable difference is the absence of the Ift/pnum mosses characteristic of northern tistnlntns. Dall and Bannister mention in their list of Alaska birds that the species is not common there. It was also taken at 8itka and Kodiak by Bischott'. The liict that this thrush builds its nest above the ground, and lays spotted eggs, if verified, Wijuld at once warrant our giving it independent rank as a species, instead of considering it as a local mce {)i pallud.

It is, however, sufficiently di-stinct from the eastern and western Hermit Thrushes to warrant our giving it a place of some kind in the systems. The young ])lumage differs from that of i^allad as do the adults of the two, and in about the same way. The olive is very much purer, with a greenish instead of a brownish cast, and the tail is very much lighter, inclining to dull ochraceous instead of rufous ; this yellowish instead of rufous cast is apparent on the wings also. The yellowish " drops *' on head, back, etc., are very much narrower than in paUad, while the greater coverts, instead of being distinctly tipped with yellowish, merely just perceptibly fade in color at tips. »>*) NOI5TII AMtilllCAN IIIUDS.

In its distrihution it is confined to the central mn^e of mountains from Fort liritlj^'er t(» Soutliern Mexico. Tliis species, there known as "Solitario," is common in the Alpine re^'ion of Vera Cruz (as well as in all the elevati'd rej^ions of Centr.d Mexico), freipientinj^' tlie i>ine woods in the «listrict of Orizalui. Mr. Sumichrast obtained it at all .seasons of tlie year at Moyoapam, in that vicinity; a Locality tlie hei^^ht of whicli approximates 2,'>0() metres. It is also found at a heii^ht of 1,200 metres, near the city of Orizaha. Mr. liidi,'way calls this hird the " llocky Mountain Hermit Tlirush." He states that he found it common in the Wahsatch Mountains, hut that, on account of its retiring: hahits, it was seldom seen. It there lives chieHy in the deep ravines in the pine re;.;ion, exhibiting' an attadiment to these solitudes rather than to the tliickets along the watercourses lower down; the latter it leaves to the T. niniiiiiioni.

The Redwinj,' can probably only claim a place in the fauna of Xorth America as an occasional visitant. Of the two siHicimens observed in (lieenland, one was shot late in ()ctol»er. It is not known to breed there. This s])ecies, during its breedinj^ season, is found oidyinthe more northern p<»rti(>ns of P^urope ; only occasionally, and very rarely, breeding so fjir south as England. It makes its appearance in that kingdom on its southern migra- tions, coming in large flocks from Northern and Xorthefistern Europe, and arrivin;; usuallv before the end of October. During their stay in England they freipient parks and pleasure-grounds that are ornamented with clumps of trees. During mild and open weather they seek their subsistence in pasture lands and moist meadows, feeding principally on worms and snails. In severe winters, when the groiuid is closed by frost or covered by snow, the Uedwings are among the first birds to suffer, and often perish in large uiimljers. During the winter they extend their migrations to the more southern por- tions of Euroi)e, to Sicily, Malta, and even to Sn)yrna. In early spring they retiun to the more central portions of the continent, and leave in May for their more northern places of resort. They nest in trees in the moist woods of Norway and Sweden. Their n(?sts resemble those of the common Fieldfare, T. pilark. The outside is composed of sticks, weeds, and coarse grass, gathered wet, and matted with Ji small quantity of moist clay. They are lined with a thick tel of fine gi-ass. The Redwing is said to possess a delightful note, and is called the Night- ingale of Norway. linnanis, speaking of this bird, claims that its high and varied notes rival even those of that far-famed vocalist. During the summer the Redwing advances to tl.*; extreme north, visiting 24 NORTH AMERICAN RIRDS. tlie Faroe Islands, Ict'Lnul, and Xortlicrn IJnssia. Tlio LToncral character of its food, its inability to feed exclusively on l>eiTies, and the fact that it perishes from starvati«»n in severe wintei-s, would seem to prove that its occun*ence in (Jreenland so late as October must have been ])urely acci- dental. It is not probable that its presence in North America will be found to Ix^ a common (!vent. The eggs measure 1.00 inches in length by .81 in breadth. The ground color is a light green with a bluish tinge tliickly covered with russet or reddish-brown spots, continent at the larger end. SrBOExuH FLANESTICUS, Honap. r/inirsfit'us, Ijonai*.

There are some variations, both of color and proportions, l)etween eastern and western specimens of the Jiobin. In the latter there is a tendencv to a lonjjjer tail, though the difference is not marked ; and, as a rule, they slightly exceed east- ern specimens in size. The broad white tip to the later,al tail-feather — so conspicuous a mark of east- ern birds — is scarcely to be fcmnd at all in any western ones ; and in the latter the black of the head is v(>rv sharply defined against the lighter, clearer ash of the back, there hardly ever l>eing a tendency in it to continue backward in the form of centrjd spots to the feathers, as is almost constantly seen in eastern examples ; of western specimens, the rufous, too, is appreciably lighter than in eastern. As regards the streaks on the throat, the black or the white may either largely predominate in specimens from one locality. Turdus misratorius. 26 NORTH AMEHICAX IJIRDS.

Habits. Scarcely any American bird has a wider range of geographical distribution, or is more numerous wherever found, than this thrush. From Greenland on the extreme iiorthea.st to the plateau of Mexico, and from the Atlantic to the Pacific, the Iiobin is everywhere a ver^^ abundant species. Single specimens have been obtained as far south as Cobaii, Guatemala. Its distribution in the breeding season is liardlv less restricted, occurring alike on tlie shores of the Arctic Seas and on the liigh lands of Vera Cruz. Ill the winter months it is most abundant in the Southern States, while in the Middle and even the Northern States, in favorable h>calities, it may be found throughout the year ; its mignitions being influenced more by the question of food than of climate.

On the Pacific Coast the Pobin is only a winter visitant in California ; a very few remaining to breed, and tliose only among the hills. They reach Vancouver Island early in ^larch, and are very abundant. In New Phiglaiid, where the liobins are held in great esteem, and where tliey exist under very favorable circumstances, tlieir numbers have very laigely increased, especially in the villages. They cause not a little annoy- ance to fruit cultivators by their depredations upon the lu-oductions of the garden, especially cherricvS and strawberries. They are a voracious bii-d, and no doubt destroy a large quantity of small fruit, but there is abundant evi- dence that this is more than compensated ])y their destruction of the most injurious insects, upon wliicli they wage an incessant war. Tlie investiga- tions of Mr. J. W. P. Jenks and Professor Tread well establish conclusivelv their great services in this direction. Tlie ex])eriments of the latter gentleman show that the nestlings of the Robin require a vast amount of animal food, forty j)er cent more than their TUKDID.K — THE TIIKISIIKS. 27 own weif»lit hom^ consumed hy tlie youni]f bird witliin twenty-four hours, and, what is more, demonstrated to be neeessarv to its existence. In Massachusetts a tew Ilobins remain thronjj:hout the yea», hut the i^reater proportion leave early in November, returning late in February or early in March. The song of the Kobin is deservedly popular. "While many of our birds |X)s.sess far superior powers of melody, and exhibit a much u^reater variety in their song, there are none tliat exceed it in its duration or extent. It is the first bird in spring to open and one of the last to close the great concert of Nature. Their song is earnest, simple, and thrilling, and is said by Audubon to resemble that of tlie European lUackbird, Tunlm mcrula. The llobin, wlien taken young, may l)e readily tamed, and soon becomes contented and accustomed to confinement. They are devoted to their young, watcliful, attentive, and provident. They begin to construct their nest in early spring before the trees put forth tlieir leaves, and often in very exposed positions. The size of the nest, in fact, makes concealment impossible. These nests ai > sometimes placed in tpiite remarkable positions, such iis the beams of a ship partly finislied, and where the carpentei-s were every day at work, and similar situations indicating a great familiarity. Their favorite ])lace is the horizontal branch of an apple-tree, about ten feet from the ground. The nest of the Itobin is a large and coarselv constructed combination of rude materials. It is composed of a base of straw% leaves, mosses, stems, and dry grasses, upon which a cup-shaped fabric of clay or mud is built. The whole is lined with finer dry grasses and vegetable fibres. They avemge 5 inch.es in lieight and the same in diameter. Their cavity is 2 J inches deep, with a diameter of 2 J, inches. The eggs of the llobin, wliich are usually five and sometimes six in num- ber, are of a uniform bright greenish-blue color, liable to fade when exposed to light, but when fresh exliibiting a very distinct and bright tint. They vary in size from 1.25 to 1.12 inches in lengtli, and in breadth from .88 to .To of an inch. Their mean measurement is 1.18 by .81. Turdus migratorius, var. confinis, Baird. CAFE ST.

In the latter respects it agrees with Meruhi of Eu- rope and Middle America; in which, however, the bill is distinctly notched, and less attenuated.

The loral feathers are soft, and not ending in bristly points. The colors are dull shades of brown, gray, or plumbeous. Most of the species, in addition to a melodious native song, possess the power of imitating the notes of other birds ; sometimes, as in the American Mcjcking Bird, to an eminent degree. All are peculiar to the Xew World, and the si)ecies are much less vagrant than those of the Turdincv, — those of the United States scarcely going beyond its northern boundary ; others, again, restricted to small islands in the West Indies or in the Pacific Ocean.

He met with its nest in a wormwood (Arfanisio) bush on the Umler of a ravine ; it contained four e«:«,'s of emerald green, sjjotted with dark olive, the simts being large, roundish, and more numerous at the larger end. The nest was composed of small twigs and rougli stalks, and lined with strips of bark and bison-wool. The female flew off to a short distance, and looked at her unwelcome visitors without uttering any com- plaint. The nests of tliis bird, so far as I have seen them, are all flat, shallow structures, with very slight depression, and loosely and rudely constructed of an intermingling of strips of bark with rootlets and the flner stems of her- baceous ])lants. Their eggs, usually four in number, do not vary essentially in size, shai)e, or marking. Tht\" measure 1 inch in length, and from .73 to .75 in breadth. Tlieir ground color is a bright greenish-blue, marked with deep olive-brown spots, intermingled with blotches of a light lilac. There are slight variations in the j>roportion of green in the shade of the ground color, and also in the number and size of the spots, but these variations are unimportant. The following are ^Ir. liidgway's observations uj)on the habits of this species. They are full, valualjle, and very carefully made : — The Oram'opU'n monttoms is a bird peculiar to the artemisia wastes of the Great Basin, being a characteristic species of the region between the SieiTa Nevada and the llocky Mountains. It is exclusively an inhabitant of the *' sage brush," and is partial to the lower portions of the country, though it is not unfrequent on the open slope of the mountains. A more unappro- priate term than " Mountain Mocking- Bird " could hardly have been chosen for this species, as its predilection for the valleys, and the fact that its song is fntirch/ its own, will show. In my o[>inion, the term " Sage Thrasher " would l»e more appropriate. In the neighborhood of Carson City, Xe\ada, these birds arrived about the 24th of ^larch, and immediately upon their arrival began singing. At this time, with the Starnclla iirf/hrfa and Poospiza helli, they made sweet music in the afternoon and early morning, in the open wastes of "sage brush," around the city. The birds when singing were generally seen sitting upon the summit of a " sage " bush, faintly warbling, in the course of the song turning the head from side to side in a watchful manner. Upon being approached, they would dart downward, seemingly diving into the bush upon which they had perched, but u})on a close search the bird could not l»e found, until it was heard again singing a hundred yards or more in the 5 ' 34 NORTH AMERICAN BIRDS. (liri'ctinn from wliiili I liad approached. This jx»ciiliar, lirciiitons, conccaltMl tli-'lit is a verv cliaraiteristic trait of this hinl, and one sure to excite atteii- tion. As the season advanced, or ahout the lOtli of April, when the pairing season was at hand, the son^ of the males l)ecame «j;reatly improved, increas- ing in sweetness and vivacity, ami full of rai>turous emotion ; their manners, also, Ik'came changed, for they had lost all their wariness. In ]>aying their attentions to their mates, the males would tlv from Imsh to bush, M'ith a ])eculiar, tremulous fluttering of the wings, which, when the hird alighted, were raised ahove the back apj)arently touching each other; all the while vibrating with the emotion and ecstasy that awer, — in this resj>ect equalling no other species of M'unina' with which I am acquainted, — is nevertheless sui>erior to most of them in sweetness, vivacity, and variety. It has a wonderful resemblance to the beautiful subtle warbling of the liiijuhiH caliniJtila, having in fact very much the sr.me style, with much of the tone, and about the power of the song of the Pi/nniffa rnbra. When the birds are engaged in incubation, the males become very silent, and one not familiar with their habits earlier in the season would think thev never had a voice ; in fact, they make no i)rotestations even when the nest is disturbed, for, while blowing the eggs, I have had the parent l>irds running around me, in the manner of a robin, now and then halting, stretching for- ward their heads, and eying iw in the most anxious manner, but remaining I^erfectly silent. When the young are hatched the i)arents become more solicitoiis, signifying their concern by a low, subdued diiick. At all times when the nest is ap]n-oached, the bird generally leaves it slyly before one approaches very near it. The nest is very bulky, composed externally of rough sticks, principally the thornv twigs of the various " sage bush " plants. Nearer the centre the principal material is fine strips of inner bark of these jdants ; and the lining consists of finer strips of bark, mingled with fine roots, and l)its of r.ildut fur. The situation of the nest varies but little, being gener.dly placed near the middle of a bush, that is, about eighteen inches from the ground. It is generally suj)ported against the main trunk, upon a horizontal bmnch. Several were found upon the ground beneath the bush, one, in fact, embedded in the soil, like that of a Pipilo ; or as sometimes the Ciise with the Har- j)orh)inchuii rvfns, others, again, were found in brush-heaps. In all cases, the nest was very artfully conce.iled, the situation being so well selected. This bird is almost Cipudly common in all parts of its habitat, within the limits indicated. In June, we found it abundant on the large islands in the Great Salt Lake, where many nests w^ere found. In autumn, it feeds, in company with many other birds, upon berries, " service berries " being its especial favorite. TrUIIIU.K — Till-; TIIUI SIIKS. 35 Gexls Cahamh. llariiorUijuchiis ru/iis.

As strtted in " Iiinls of Xer or the first week of October, its stay varying with the season and the su])ply of its food. It is somewhat irregularly distributed, common in some jjortions of this section, and rare or even unknown in others. It is not found near the sea-coast beyond Massachusetts. It passes the winter in the Southern States, even as lar to the north as Virginia, and is in full song in the neighborhood of Sa.annah as early as the first of ^larch. The song of this Thrush is one of great lieauty, and is much admired by all who ap]>reciate woodland melody of t\\Q sweetest and liveliest type. It is loud, clear, emphatic, full of variety and charm. Its notes are never imi- tative and cannot be mistaken by any one who is familiar with them, for those of any other bird, unless it may be some one of its western congenei's. It is a very steady })erformer, singing for hours at a time. Its notes are given in a loud tone, and its song may often be heard to (piite a distance. In obtaining: its food the Ihown Thrush is at times almost rjisorial in its habits. In the early spring it scratches among the leaver of the forest for worms, coleo])terous grubs, and other forms of insect food. IJy some it is charged with scratching ui> the hills of early corn, but this is not a well- founded accusation. Berries of various kinds also form a large ])art of its food, and among these the small fruit of our gardens must l)e included. This Thrush is a very affectionate and devoted bird, especially to its young. It is also j)rompt in go'""' to the assistance of others of its species when in trouble. Whenever intruders a})proach their nests, especially if their young are far advanced, they manifest the deepest anxiety, sometimes even making a vigorous defence. The writer has a very distinct recollection of having encountered, together with a younger brother, an ignominious defeat, when making his fii-st attem])t to inspect the nest of one of these birds. The Brown Thrush is jealous of the intrusion of other birds of its own species to a too ch)se ])roximity to its nesting- jdace, and will assert its love of seclusion by stout battles. In Louisiana the construction of the nest is connnenced (piite early in ^larch ; in Pennsylvania, not until May ; and in the Xew England States in the latter ])art of that month. The nest is usuallv not more than two or three feet from the ground. It is built in a low bush, on a cluster of briers or amon^ vines. I have known it to be Tl'RDID.E — THE TIIUrSIIES. 31) jjlaced in the interior of a heap of Imishwood loosely thrown to-^cther. I have never met with the nest built upon the grounil, but in Sj»rinij:liehl, and in other dry and sandy loealities, this is by no means an uncommon occur- rence. These nests are fre([uently jdaced in close proximity to houses, and sometimes in the very midst of viUaj^es. The nest of the Thmsher is larue, and roughly but stromjly built. The base is usually made of coarse twigs, sticks, and ends of branches, tirndy interwoven. Within this is constructed an inner nest, c(mi])nscd of tlried leaves, strips of bark, and strong black tibrous roots. These are lined with finer roots, horse-hair, an occasional feather, etc. The eLTiis are usually four, sometimes five, and r.irelv six, in number. They vary both in the tints of the ground c(dor, in those of their markings, and slightly in their shape. Their length varies from .99 to 1.12 inches, with a mean of 1.05. Their breadth ranges fnmi .70 to .87 of an inch; mean breadth, .81. The ground color is sometimes white, marked with tine reddish- brown dots, continent at the Lirger end, or forming a broad ring around the crown. In others tlie markings have a vellowish-brown tint. Sometimes the ixround coh)r is a light green. Haxporhynchus rufus, \ar. longirostris, cahan. TEXAS THBASHEB. Orphfm Jfniffirostris, Lafu. \\. Z. 18.38, :»'>. — In.

Habits. The eggs of this species are hardly distinguishable from those of the common Brown Thrasher {H. ri'J)(s), of the Atlantic States. The color of their «.TOund is a gi'eenish-white, which is thickly, and usually com- pletely, covered with fine markings of a yellowish-brown. They have an average length of 1.13 inches, ])y .79 in breadth. So far as I have had an opportunity of observing, they do not vary from these measurements more than two per cent in length or one per cent in breadth. Their nests are '=!ually a mere jdatform of small sticks or coarse stems, with little or no '^sion or rim, and are placed in low bushes, usually above the upj>er branches. In regard to the distinctive habits of this species I have no information. Harporhynchus cinereus, Xantus. CAFE ST. LUCAS THSASHEB. Harporlnnrrhus cinrrcua, Xaxtis, Pr. A. N.

So far as is at present known in regard to this species it appears to be confined exclusively to the peninsula of Lower California. It has, at least, been met with nowhere else. Mr. Xantus found it quite numerous in the vicinity of Cape St. Lucas, in a region which, as he descriljes it, was singularly unpropitious.

Adjacent regions of United States and Mexico, southward. Cordova, Orizaba, Mirador; Mazatlan, Cohma, Oaxaca. Specimens from the Rio Grande across to Mazatlan represent one species ; but those from the latter locality are somewhat darker in colors, though this "uay be owing, in part, to the fact that they are winter birds. Considerable differences in proportions may often be noticed between individuals, but nothing strikingly cliaracteristic of any particular i-egion. The specimens of the Mazatlan series (37,326 (J, 51,523, and 51,525^) have tails considerably longer than any of those from the Rio CJrande, the excess amounting in the longest to nearly an inch ; but one from the same locality has it shorter than any of the Texas specimens. In its perfect plumage, this species has both rows of coverts distinctly tipped with white ; but in the faded condition of midsummer, the bands thus produced are hardly discernible, and the spots below become very obsolete. Habits. This interesting species appears to be common in AVestem Texas, the vallev of the IMo Grande, and Western Mexico. It was met with in these regions on the several railroad surveys, and is described by Dr. Heer- mann as possessing musical powers surpassed by few other birds. When alarmed it immediately hides itself in a thick covert of underbrush, whence it is almost impossible to dislodge it. Its food consists of fruit and berries when in their season, of insects and their larvae and of worms. These it collects botli among the trees and from the ground, on the latter of which it spends mucli of its time. Mr. J. H. Clark states that the nest of this bird is very similar to that of the Mocking-Bird, but is finer and much more com- pact. He adds that it is oftener found among the Opantia than elsewhere. It is a quiet bird, rather shy, and keeps closely within the clumps of the chaparral. For a bird of its size it makes an unusual noise in flying. At Ringgold Barracks Mr. Clark's tent was pitched under a como-tree in which there Mas a nest of these birds. They were at first shy and seemed quite disposed to abandon their nest, buc, however, soon became accustomed to their new neighbor, and went on with their parental duties. The position of their nest had been ver}^ judiciously selected, for it was during the season of the black fruit of the como, which is somewhat in the sha])e and size of a thimble, with a ]»leasant milky pulp. These constituted their principal f<>od. The eggs in this nest were five in number. Lieutenant Couch met Avith it from Brownsville to Duranjro, where it had alreadv paired as earlv as TUKDID.E — THE TIIRUSIlK- 43 Februriiy. He ribes it as exceedingly taii.j aiid gentle in its habits, and witli a song remarkably melodious and attractive. Perched on the topmost bou'di ol' a tlowcring mimosa, in the presence of his consort, the male will pour forth a volume of must enchanting music. Their nest is generally very nearly flat, measuring nearly six inches in circumference., antl scarcely more than an inch in its greatest thickness. It has hardly any distinct cavity, and hollows but very slightly from the rim to the centre, its greatest depres- sion having barely the deptli of half an inch. The nests are composed of long coarse fibrous roots, rudely, but somewhat compactly interwoven. T\ir inner framework is constructed of the same materials intermixed with ti:e finer stems of grasses. ^Ir. H. E. Dresser states that in the vicinity of ^latamoras these birds are fond of freiiuenting small villages, anvered with fine brown spots. Harporhynchus curvirostris, var. palmeri, Kidgway.
