Falcons
1. Peregrine falcons:Type:Bird Diet:Carnivore Average life span in the wild:Up to 17 years Size:Body, 14 to 19 in (36 to 49 cm); wingspan, 3.3 to 3.6 ft (1 to 1.1 m)Weight:18.8 to 56.5 oz (530 to 1,600 g)
2. Lanner falcon:
The lanner falcon is a handsome and powerful bird of prey, with grey-brown to slaty upperparts, a creamy-white throat and underparts, sometimes with dark spots or striping, and a characteristic reddish-brown crown on the head, which helps to distinguish it from the smaller peregrine falcon, Falco peregrinus. The white cheeks contrast with dark eye stripes and a long, dark ‘moustache’ below the eye, and the eye ring is bright yellow . The body is quite slender, with a long, barred tail and long, relatively blunt-ended wings that are dark at the tips. The female lanner falcon is usually larger, darker and more patterned than the male, while juveniles are much browner in colour, with heavily streaked underparts, pale blue-grey facial skin, and a duller crown. The lanner falcon shows considerable regional variation in size, colouration and degree of spotting and barring, with five subspecies currently recognised . The species is usually fairly silent, but at its breeding sites may give a variety of screams and cackling calls.

3. American Kestrel:
- Size & Shape The slender American Kestrel is roughly the size and shape of a Mourning Dove, although it has a larger head; longer, narrow wings; and long, square-tipped tail. In flight, the wings are often bent and the wingtips swept back.
- Color Pattern American Kestrels are pale when seen from below and warm, rusty brown spotted with black above, with a black band near the tip of the tail. Males have slate-blue wings; females’ wings are reddish brown. Both sexes have pairs of black vertical slashes on the sides of their pale faces—sometimes called a “mustache” and a “sideburn."
Calls: American Kestrels have a fairly limited set of calls, but the most common one is a loud, excited series of 3-6 klee! or killy! notes lasting just over a second. It's distinctive and an excellent way to find these birds. You may also hear two other common calls: a long whine that can last 1–2 minutes, heard in birds that are courting or feeding fledglings, and a fast chitter, usually used by both sexes in friendly interactions.
