context_page_description: The nankeen kestrel is a raptor native to Australia and New Guinea. It is one of the smallest falcons, and unlike many, does not rely on speed to catch its prey. Instead, it simply perches in an exposed position, but it also has a distinctive technique of hovering over crop and grasslands.
context_section_description: The nankeen kestrel is a small, slim falcon 28 to 35 cm (11 to 14 in) long with a wingspan of 66 to 78 cm (26 to 31 in). The male weighs 121 to 195 g (4.3 to 6.9 oz) while the female weighs 115 to 273 g (4.1 to 9.6 oz). It has pale rufous upper-parts with contrasting black flight-feathers and is finely streaked white below, with a black subterminal band. The cere, eye-ring, and legs are yellow. The male has a pale grey crown and tail with a darker grey tear-mark, while the female and juvenile have a pale rufous crown and finely barred rufous tail. Plumage varies considerably in detail, and some birds can look very scruffy, but the slim build, small size and distinctive straight-winged hovering habit make identification easy. The only other Australasian raptors to hover are the elanid kites, which are much lighter in colour and a little larger, and the brown falcon, which is much larger and more heavily built, and hovers only with difficulty. Altogether, the nankeen kestrel looks just like a pale, less patterned, and smaller derivate of the Eurasian kestrel, which it indeed is (see Gloger's Rule, Bergmann's Rule).
