The Wilson Snipe, Capella delicata, is the bird that is known to the hunter
and the public in general as the Jack Snipe. It received that name from the early
Colonists on account of a similar bird by that name in the Old World. The orni-
thologists gave it its present official name in recognition of Alexander Wilson,
the father of American ornithology and the first one to differentiate it from the
Old World form.
It is distributed in its habitats throughout continental North America and in
its fall migration reaches northern South America. However, most of its south-
ward migration is only a short distance below the frost line, or, where conditions
assure it of unfrozen mud in which to probe for food. It is an early spring
migrant, following the retreating frost line into the north. Cold weather, how-
ever, is no handicap, for where spring waters keep ground unfrozen this snipe may
remain quite far north.
I have found it near Dillon, Montana, in February in sub-zero weather, and
there are authentic records of it wintering in British Columbia. It is a common
winter visitant of our spring runs about the Salt Lake Valley.
Its habitat is fresh water marshes, moist meadows or pasture land springs,
or other fresh water vegetated edges, and not the open shoreline like that of
most other shore-birds, nor alkaline nor salt-water marshes, though in migration
it may be found there and in a variety of other places. I have observed it on the
lawn at Mount Olivet Cemetery, near Community Camp in Big Cottonwood
Canyon, and in sage brush a half mile west of Utah Lake.
The Wilson Snipe and the Woodcock are the only two species of shore-birds
on which is allowed an open shooting season. The Woodcock has a very restricted
one, but the Wilson Snipe has a cross-country open season corresponding with
that of the migratory waterfowl. There are several very good reasons why this
shore-bird can maintain its population status in suflicient numbers to justify (at
least in the judgment of Pish and Game Commissions) an open shooting season:
1st. Its wide distribution and nesting range, which is from coast to coast,
and from the central tier of states to the sub-arctic.
2nd. Its choice of nesting sites, preferring grassy hummocks midst muddy
or water surroundings. In this environment it seems able to bring a larger brood
to maturity than other shore-birds that nest in the open where they may be
preyed upon by predatory birds and their nests and young scented out by animals.
3rd. Its solitary habits. Most other shore-birds concentrate in large flocks
and fly in such close formation that a well-directed shot will not only bring down
a large number but mortally injure many more. Dr. Elliot Coues records a count
of 210 fallen birds from a single shot from one of the old fowling pieces of those
days.
Now the opposite would be the case with the Wilson Snipe. It would more
likely be 210 shots for one bird. It flushes, generally, singly from under your feet as

tlioiigli it had been released by a spring, and pursues such a fast zigzag course,
low over the marsh vegetation, that it is hard to follow its flight, let alone draw
a bead on it. But when it rises almve the marsh herbage it flies straight and then
it is no more a diflicult target than any other bird of like size and speed. Hunting
it is a favorite pastime for fast trigger sportsmen.
I have always found it a difficult bird to show anyone in the fleld, so one
should first know what it looks like from skins, mounted specimens, or pictures,
and then it can be recognized in the fleld by its flight and alarm calls. Another
line unmistakable fleld characteristic is its nuptial flight. This is performed over
its nesting or prospective nesting area and is a series of deep arc dives and ascen-
sions, not in the plane of the dive, where it continues in like manner for several
minutes, each dive following the previous one to describe a circle of less than a
thousand feet diameter around the nest site. The peculiar, pleasing whirring
sound one hears is produced by the combination of tail feathers, held down at
right angles to the body during the dive, the fast close movement of the wings
to the body and the addition of the voice.

A Half Hour with a Prairie Falcon
Wandering along a stream bottom in the hills northeast of Benicia, Solano
County, California, on November 30, 1937, I spied at a distance of about one hun-
dred yards a large bird sitting on a fence-post on one side of the little valley.
I withdrew from my pocket my 25-power telescope, a very efficient instrument
for distant observation, and assumed a comfortable position by lying on my back
against a small hummock, with the four-section extensions of the glass resting
between my updrawn knees, and watched the bird, a Prairie Falcon, as it perched
in the sunshine of the late afternoon.
While nothing sensational happened during this period I found it very pleas-
ant to rest after a rather long stroll and at the same time to note the activities
of this interesting species. Though not rare, one does not have the opportunity
of observing Prairie Falcons on every fleld trip in this region. The bird’s entire
time was spent between preening its feathers and surveying the country in all
directions. The head, during these two operations, was almost continually in
motion except for the short moments of observation. A full three-quarter turn
of the head was often made. Preening, during the period the bird was under
observation, began at the base of the neck, extending to the wings, both inner
and outer surfaces, returning occasionally to the base of the tail probably to the
oil gland. The body feathers, both front and back, were taken care of; one wing
was stretched to its full extent, followed by stretching first one leg, then the
other. For short periods it stood only on the left leg, the other being drawn a
little upwards to the body feathers, and used twice to sci’atch the right side of the
head.
The sun set over the top of the opposite hill, reducing the excellent visibility
which I had enjoyed, so I approached the perching site. At about fifty yards, the
so-called “vermin” sprang upwards in the air wuth a tew heavy wing-flaps, the
legs dangling for the first twenty or twenty-five feet, then drawn up into the
feathers, as it sailed away on long, pointed wings into the distance after having
entertained an eavesdropper into its private domestic affairs for an enjoyable
half-hour.

Observation of an Immature Cooper Hawk
On Sunday, February 27th, about 11 o’clock in the morning the writer was
walking along the easterly shore of Lake Merced where he reached a point about
midway between the pumping plant and the southerly end of the lake. From the

willows now partly submerged by high water and close to the shore line a Cooper
Hawk was tlushed, but apparently unafraid, it Hew a distance of about fifty yai'ds
and then alighted ag;iin in the willows not more than twenty yards from the lower
pathway which circles the lake.
it was in plain view and easily observed. It perched facing the writer
with its tail spread fan-like and wings about half extended. Several times it
shook itself as if attempting to dry its feathers, but as the day was overcast, there
was little or no sun to help in this seeming drying-process. No other hawk was
noticed in this vicinity.
Two facts indicated that it was an immature Cooper Hawk — the breast was
stieaked with blackish lines instead of barred with brownish ones; secondly, the
bird did not show the wariness usually characteristic of an adult. It did not flush
easily, refused to fly at clapping of hands, and left only when the writer ap-
proached making considerable noise as he advanced.
An excellent differentiation between the adult and the immature bird is to
be found in John Richard May’s book entitled “The Hawks of North America,”
page 28. Perhaps thirty minutes in all were spent observing this hawk.

March Field Trip
Due to the uncertainty of the weather, only three members, Robert Wells,
Charles Hausen and Harold Kirker, attended the March field trip on Sunday, the
13th. With the exception of a little rain the weather was fair.

interesting observations at Tomales Bay were those of a White-tailed Kite and
a Prairie Falcon; both of these species being uncommon in Marin County.
Black Brant were seen in large numbers; one flock of about 150 were feeding
in the marshes along the shore. Leaving Tomales Bay we returned by the coast
route to Mill Valley.

began in his young boyhood fifty jmars
ago. His humorous account of these
early beginnings and his experience as
a taxidermist evoked a great deal of
laughter from his listeners.
