aptures them in a sportsmanlike manner by "waiting on"
or hovering on rapidly beating wings over his game and dropping on it
with deadly aim. His call is a high, rapidly repeated _Killy-killy-killy_.
The three to seven eggs, finely marked with reddish brown, are laid in a
hollow limb or similar situation in April.

AUDUBON'S CARACARA

_Polyborus cheriway cheriway_

A falcon-like Vulture with a bare face, black cap,
white throat, breast and nape; the rest of the
plumage is black, the tail barred with white. L.
22.

_Range._ Mexican border and southward; south
central Florida.

In the eastern United States the Caracara is found only in the Kissimmee
prairie region of southern Florida where its presence, so far from
others of its kind, furnishes one of the problems in distribution which
stimulate the imagination of the faunal naturalist.

OSPREYS. FAMILY PANDIONIDAE

OSPREY

_Pandion haliaetus carolinensis. Case 3, Fig. 14_

The Osprey or Fish Hawk is often miscalled
'Eagle,' but it is a smaller bird with white,
instead of blackish underparts. L. 23.

_Range._ The Osprey is found throughout the
greater part of the world; the American form
occurs in both North and South America and winters
from the southern United States southward,
starting northward in March.

Washington, uncommon S.R., Mch. 19-Nov. 30.
Ossining, common T.V., rare S.R., Apl. 3-May 26;
Sept. 29-Oct. 20. Cambridge, rather common T.V.,
Apl.-May; Sept.-Oct. N. Ohio, rare S.R., Apl.
20-Oct. Glen Ellyn, two records, May and Sept.

The Osprey, or Fish Hawk, feeds on fish and nothing but fish. He is,
therefore, never found far from his fishing grounds, where no one who
has seen him plunge for his prey and rise with it from the water will
doubt his ability to supply his wants. Ospreys usually nest in trees at
varying distances from the ground, but sometimes on cliffs or even on
the ground itself, and return year after year to the same nest. The
Osprey's alarm note is a high, loud, complaining whistle, frequently
repeated. The eggs are laid in late April and early May. They are
usually four in number, buffy white, heavily marked with chocolate.
