The Kestrel is generally distributed, and in most districts 
not uncommon, so that it appears to be the most numerous of 
our rapacious birds. It is especially remarkable for its habit 
of hovering over the fields when searching for its prey, which 
consists chiefly of mice, arvicolse, and shrews, in looking for 
which among the grass it balances itself, with a quivering 
motion of the wings, at the height of twenty or thirty feet. 
It occasionally destroys birds also, especially young larks, 
thrushes, and lapwings, and feeds on beetles and other 
Coleoptera, as well as earth-worms and lizards. At the 
commencement of the breeding season it is remarkably voci- 
ferous. It often takes possession of the deserted nest of a 
crow or magpie, but in rocky tracts breeds on clitFs or craggy 
banks. The eggs, which vary from three to five, are broadly 
elliptical or roundish, pale orange-red, or reddish-white, 
confusedly dotted or patched all over with dull brownish-red, 
and average 1| inch in length, IJ in breadth.
