The American Kestrel
The American Kestrel is perhaps the most colorful, smallest, numerous, and most widespread North American falcon. Of the 13 kestrel species that occur throughout the world, only one is found in the Western Hemisphere, where 17 subspecies are recognized.
Found from Alaska to Tierra del Fuego. This colorful falcon is sexually dichromatic; the males has blue-gray wings and a rufous tail with a single broad sub-terminal black band, while the wings and tail of the female are rufous with black bars across their lengths. The female is about 10% heavier than the male.
They inhabit open areas covered by short ground vegetation where it hunts mostly from perches, frequently from utility wires along roadside, but also by hovering. The hovering bird faces into the wind with head apparently fixed in space, while the wings alternately flap and glide and the tail constantly adjust to each eddy in the breeze. The kestrel is attracted to human-modified habitats, such as pastures and parkland, and often is found near areas of human activity.
The American Kestrel nest in tree cavities, woodpecker holes, crevices of buildings, holes in banks, nest boxes or, rarely, old nests of other birds. They have a highly adaptable behavior and lives just about everywhere, as long as there is some open ground for hunting and conspicuous places on which to perch. The American Kestrel is a small falcon ranging from 9-12 inches tall, with a wingspan of 20-24 inches and weight ranging from 2.5-6 ounces.
They have rufous back and tail with two dark mustache marks on face. They have a curved bill with “tooth” on upper mandible, long pointed wings, long tail, legs and toes rather short and “eye-spots” on back of head. The male has blue-gray wings and a lightly spotted chest and belly. The larger female has rufous wings barred with back, and streaking on the chest. Juveniles are similar to adults.
Breeding season is March-June depending on where you are geographically. For up to six weeks before egg laying, females are promiscuous, mating with two or three males. Once a female settles with one mate, the pair mates frequently until egg laying. They will lay 3-7 eggs (usually 4- 5) over a period of 2-3 days. Eggs are white, cream or pale pin
