It is most often seen following the coast-line during migrations
where it takes toll of Ducks and shore-birds. Three to four heavily
marked, brownish eggs are laid in April.

PIGEON HAWK

_Falco columbarius_

A small Hawk, about the size of a Sparrow Hawk.
The adult is slaty blue above, with a rusty collar
and a barred, white-tipped tail; below buff,
streaked with blackish. Young birds have the
upperparts blackish brown. L. 11.

_Range._ Breeds north of, and winters chiefly
south of the United States. Migrates northward in
April and May, and southward in September and
October.

We know this Hawk as a not common migrant generally seen in open places
and along the shores. It feeds chiefly on small birds.

SPARROW HAWK

_Falco sparverius sparverius. Case 1, Figs. 7, 8; Case 3, Figs. 5, 6_

The male has the tail with only one bar; the
breast unmarked; the abdomen with black spots;
while the female has the tail with several bars,
the underparts streaked with brownish. In both
sexes the bright reddish brown of the upperparts,
black markings about the head, and small size are
gold field characters. L. 10.

_Range._ Sparrow Hawks are found throughout the
greater part of the Western Hemisphere. Our
eastern race inhabits the region east of the
Rockies and is migratory at the northern limit of
its range. Southern Florida specimens are slightly
smaller and darker and are known as the Florida
Sparrow Hawk (_F. s. paulus_).

The Sparrow Hawk is one of our commonest and most familiar Hawks. He is
a handsome little Falcon, and though his prey is chiefly humble
grasshoppers, he c
