Birds of prey — and American kestrels in particular — have been significantly harmed by chlorophacinone, one of two poisons targeted in the law, according to Lisa Owens Viani, director of ...
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 ...
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.
