Pren of Newcomb & Gauss Salem, Mass, PREFACE. This List of the Birds of Eastern Massachusetts has been prepared at the request of the Museum Committee of the Peabody Academy of Science with the intention of encour- aging a legitimate popular interest in an exceedingly attractive and economically valuable group of the local fauna. Of the species mentioned in the List all but about fifty have been recorded from Essex County and a very large proportion of them are on exhibition in the Museum, where they may be seen daily by everyone interested. It is very much desired to obtain for the Museum as com- plete a representation as possible of the native fauna and it is hoped that all persons having an opportunity to secure local examples of species not in its collection, will aid in so doing. Records of species new to the Essex County fauna or to the district treated in this List will also be welcomed by the author. 239447 CONTENTS. PREFACE. INTRODUCTION. LIST OF BIRDS OF EASTERN MASSACHUSETTS. INDEX. SEASONAL CHARTS. INTRODUCTION. The purpose of this little work is to provide the bird- student in eastern Massachusetts with a handy pocket reminder of " what, when, and where" to seek. To this end the booklet is made as compact as possible, with sufficient blank space for brief notes, and follows the gen- eral plan of a previous one by the same author (Annotated List of Birds of Wellesley and vicinity) covering a much smaller area. Its field is all of Massachusetts east of the lowlands along the Connecticut River, including Worcester county and all that part of the State east there-of, the off-shore islands and the coastal waters. It is prepared, however, with particular reference to the local records and other features of especial interest to residents, temporary or permanent, of the county of Essex. This is not the place for a detailed discussion of the avifauna of the district as a whole or that of Essex county in particular. For such, the student should consult Howe and Allen's " Birds of Massachusetts" and Townsend's " Birds of Essex County" respectively. A few brief state- ments, however, are permissible. As will be readily appreciated, the district as a whole is by no means a homogeneous one. Three general subdi- visions may be recognized: (1) the immediate sea-shore, with its wealth of marine and coastwise 'water-birds; (2) the main mass of the land area, lying in the lower transi- tion life zone, its southern part showing distinct austral tendencies; and (3) the highlands of Worcester county in the northern and western part (Princeton, Winchendon, etc.), culminating in Mt. Wachusett (2018 feet), and char- O INTRODUCTION acterized by a distinctly more boreal facies. This boreal element is also found in the cold bogs and swamps of the lower levels to the eastward. Placed as it is on the shore of the North Atlantic Ocean, with the long arm of Cape Cod and the neighboring islands reaching far out into the sea, an exceptional number of sea and shore birds might confidently be expected; while the mainland part of the district, lying adjacent to the coast, naturally becomes an important migration route for the land birds. The sea also acts as a barrier to limit the eastward flight of wanderers from the West, South and North. These facts, combined with the populous charac- ter of the district, which probably contains a larger num- ber of people interested in bird life, either as sportsmen, students, or nature-lovers, than any district of equal size in the country in proportion its population, naturally result in a a very full and general knowledge of the native bird life of the district, and the speedy detection of wan- derers whenever they appear. Essex County, with its coastal waters, shares the charac- teristics of the district as a whole in a marked degree, though lacking any elevation of special note. The county is of particular interest ornithologically for being the scene of ]the discovery of the Ipswich Sparrow, a bird with exceptionally interesting geographical distribution. The county also forms apparently the northeastern limit of the breeding range of several species, e. g., the Long-billed Marsh Wren, Orchard Oriole, and Yellow-breasted Chat. For a full treatment of the ornithological features of the county, the reader should consult the work previously cited. The List contains 390 species and subspecies. Of these three are probably or certainly extinct; several more are extirpated; three are believed to be hybrids; five or six are known or believed to have been introduced; of about INTRODUCTION 7 375 remaining, 165 are popularly distinguished as water- birds and 210 are land-birds. Of these, 29 water-birds and 37 land-birds are accidental wanderers from various points of the compass, chiefly from the West and South; 30 more are of decided rarity, leaving about 280 species of some- what regular occurrence, of which about three-sevenths are water-birds, a relatively large proportion due to the coast- wise situation. For the convenience and better information of the user of the list, the extinct and extirpated species, hybrids or problematical forms, and introduced species which now form an integral part of our avifauna, have been inserted in their systematic places, as nearly as possible. The sequence of species is that of the checklist of the American Ornithologists' Union, 3rd edition, revised, pub- lished in 1910. Under each species is given the checklist number, for easy reference; one or more vernacular names, that standing first being the one adopted by the A. O. U.; the scientific name as given in the checklist, accented for the benefit of those whose memory is short or classical training imperfect; notes relating to numerical abundance and seasonal distribution— whether resident, migrant, or otherwise; the dates between which the species has been observed here; its preferred haunts; and the location of the nest and time when eggs have been found, if it breeds. These data have been compiled from a variety of pub- lished sources and from considerable personal observation in many parts of the territory covered. The dates of arriv- al and departure are in the main those given for the State by Dr. G. M. Allen in his New England list published by the Boston Society of Natural History in 1910. These have been modified, however, in numerous instances, with reference to the eastern part of the State, from other sources, notably Mr. William Brewster's " Birds of the Cam- bridge Region" and Dr. C. W. Townsend's 4< Birds of Essex County," and from personal and other memoranda. 8 INTRODUCTION In explanation of the typography used in connection with the dates it may be well to state that extreme or unusual dates are commonly cut off from the usual by parentheses. Thus " May 5) 10 - 25 (June 3; Aug. 26) Sept. 10 - Oct. 11 (Nov. 3" indicates that while the species usually appears about May 10 in the spring and Sept. 10 in the fall, and disappears by May 25 and Oct. 11, yet individuals have been observed as early as May 5 and Aug. 26, and as late as June 3 and Nov. 3. The seasonal chart is based on the dates given in the text. To find out what birds may be expected to occur at a given time take the vertical line at the approximate date desired and follow it downward; it will cross the seasonal distribution lines of all species likely to be found here at that time. A dotted seasonal line indicates marked irreg- ularity or uncertainty of occurrence ; a continuous one, strong probability or certainty. It should be borne in mind that the dates given are for the entire eastern part of the State. As a rule, dates of arrival during the north- ward movement will be somewhat (2-5 days) later in the northern part of the district (e. g., Essex Co.) than in the southern, and vice versa. In the southward movement, more variability may be expected in dates both of arrival and departure, but especially the latter. Acknowledgment has already been made at the proper places of indebtedness to certain sources of published information : to these should be added the files of the u Auk." In addition I wish to express my obligations to Dr. C. W. Townsend for several notes and records secured since the publication of his *' Birds of Essex County" (accredited to C. W. T. in list); to Mr. H. C. Farwell of Salem for his notes on the Egret at Newbury in 1911 ; and to Mr. C. R. Lamb for his exceptionally early record of the Shoveler. Above all, my thanks are due to Dr. G. M. Allen for his numerous helpful suggestions and for reading the manuscript. INTRODUCTION 9 A word may not be amiss relative to the frontispiece, from a photograph of Egg Rock, taken from the Nahant shore. This rocky islet is of ornithological interest, like many others off our shores, doubtless having acquired its name from being the nesting-site of several species of terns or " Mackerel Gulls." The picture also shows well the rugged character of much of the " North Shore." LIST or BIRDS OF EASTERN MASSACHUSETTS. M.— Migrant; R.— Resident; V.— Visitor; S. R.— Summer Resident; W.
