Gray-headed kite
The gray-headed kite is a raptor found in open woodland and swamp forests. It shares the genus Leptodon with the extremely rare white-collared kite. It breeds from eastern Mexico and Trinidad south to Peru, Bolivia, Brazil and northern Argentina.
Description
The gray-headed kite is 46–53 cm in length and weighs 410-605 g. The adult has a grey head, black upperparts, white underparts, and a black tail with two or three white bars. The bill is blue and the legs grey. The flight is a deliberate flap-flap-glide.Immature birds have three colour morphs; the light phase is similar to the adult, but has a white head and neck, with a black crown and eyestripe, black bill and yellow legs, closely resembling the Black-and-white hawk-eagle. The rufous phase has a reddish neck with a white throat, black malar stripes and a black, long crest closely resembling the adult Ornate hawk-eagle. The dark phase has a blackish head, neck and upper parts, and dark-streaked buff underparts closely resembling the Black hawk-eagle. The sophistication in the mimicry of these juveniles is remarkable and has only been described a few times.
