American kestrels in Canada and the northern United States typically migrate south in the winter, some of them converging with resident kestrels of smaller size in Mexico, [30] [31] sometimes going as far as Central America and the Caribbean. Birds that breed south of about 35° north latitude are usually year-round residents.
American kestrel populations have been declining across the Northeast for decades. In New Hampshire, the bird is listed as a "species of greatest conservation need," while other states, including ...
The American kestrel is the only New World species termed "kestrel". The molecular data of Groombridge [ 1 ] as well as morphological peculiarities (like grey wings in males and a black ear-spot) and biogeography , strongly support the view that this species, among the Falco falcons, is not a kestrel at all in the phylogenetic sense but perhaps ...
Troubling declines for American kestrels Another concerning trend occurring in Cascade County and being observed nationally is a continued decline in the numbers of American kestrels. “Kestrels ...
The malar-striped kestrels apparently split from their relatives in the Gelasian, roughly 2.0–2.5 million years ago (Mya), and are seemingly of tropical East African origin. The entire "true kestrel" group—excluding the American species—is probably a distinct and quite young clade, as also suggested by their numerous apomorphies.
Penny looks like a miniature-sized red-tailed hawk or even a fluffy, young falcon, but the American Kestrel is a species all its own. OK, technically, the kestrel is the smallest falcon species on ...
For instance, the kestrel is a type of falcon in which males are the primary providers, and the females are responsible for nurturing the young. In this species, the smaller the kestrels are, the less food is needed and thus, they can survive in environments that are harsher. This is particularly true in the male kestrels.
Look for plenty of warblers in the spring and birds of prey in the fall, including American kestrels and ospreys. In Queens, Jamaica Bay Wildlife Refuge sprawls over 9,000 acres and offers ...
