They live in. In March I noted that a pair of American kestrels (Falco sparvarius) appeared to once again be nesting between the outer walls in our hay shed. For many years kestrels, also called sparrow hawks, have raised a brood in our shed (Lookout CA). This year was no exception. Leonard and I can watch the kestrel.

with the American Kestrels to provide an accurate at-a-glance method of aging young nestlings, and to better plan nest box visits for nestling banding. We hope that such a guide will be significant to those interested in Kestrel conservation, as well as those with a general interest in these falcons.

SEQUENCE OF MOLTS AND PLUMAGES American Kestrels begin to acquire juvenal plumage as nestlings; this molt is completed soon after Size: KB. Today, I had the opportunity to band American Kestrels with the Pennsylvania Game Commission at State Game Lands # SGL # in Lehigh County has excellent grassland habitat and is home to numerous kestrels that require this open environment.
In order to keep track of breeding success of this important grassland bird, the game commission bands chicks every year. North America’s littlest falcon, the American Kestrel packs a predator’s fierce intensity into its small body. It's one of the most colorful of all raptors: the male’s slate-blue head and wings contrast elegantly with his rusty-red back and tail; the female has the same warm reddish on her wings, back, and tail.
Hunting for insects and other small prey in open territory, kestrels perch. Not a expert either but my vote, fwiw, is for a 1st spring (2nd cal year) female.
1st spring because of rounded whitish primaries tips (and rather short looking wings?), contrast between moulted scapulars and new ones (2 kinds of feathers), boldly marked upperparts, apparently worn coverts (with a few new feathers intermixed), streaked underparts, broad black and rusty tail bars.

The American Kestrel(Falco sparverius) is a sexually dichromatic falcon that exhibits considerable individual plumage variability. For example, the anterior extent of the black dorsal barring in juvenile males has been used throughout North America as one of several aging criteria, but recent data demonstrate that the variability among individual Southeastern American Kestrels(E S.
