straying into the western and southern parts of the latter continent. It is replaced 
in the New World by the so-called American sparrow-hawk ( F. sparvorius), in 
which the centre of the crown of the head of the male is rufous, and the 
wing-coverts blue with black spots. Although its chief food consists of mice 
and voles, the kestrel occasionally kills small birds, and will also eat frogs, beetles, 
worms, and grubs, while in India it frequently devours lizards. That it will

occasionally kill a young partridge or chicken is doubtless true, but such small 
robberies are far more than counterbalanced by the benefits it confers on the 
agriculturist by the destruction of hosts of pernicious rodents, and it ought

occasionally placed in a hollow tree, the nest is more generally situated among 
rocks or old buildings, while still more frequently the deserted nest of some 
other bird, such as a crow, magpie, or raven is taken advantage of. The eggs, 
usually four or five, but sometimes six in number, may be either mottled all over 
with brownish red or orange, or blotched with these colours upon a light ground. 
They are generally hatched late in April, or early in the following month.
