THE KESTREL, (Falco tinnunculus,)
Is the commonest of all the British Hawks, and may be seen in almost all parts of the country hovering over the fields in search of mice and other small animals. His flight is very peculiar. He advances only for a short distance at a time, and then suspends himself in the air by very short but quick movements of his wings. If no prey make its appearance beneath him, he then goes on a little further, and again remains stationary, but the moment a mouse or other small quadruped stirs amongst the grass, his wings close, and he descends with the greatest velocity. The Kestrel will also feed upon small birds and insects.
The Kestrel is a handsome little Hawk, from twelve to fifteen inches in length, with a blue beak and yellow cere and feet. Its plumage is reddish brown or fawn colour, elegantly marked with black spots and bars. Its nest is built among rocks, or in the holes and corners of old buildings and church towers, and the female lays four or five eggs, which are reddish white, with brown spots.
