The square-tailed kite (Lophoictinia isura) is a medium-sized bird of prey in the family Accipitridae, which also includes many other diurnal raptors such as kites, eagles and harriers.
German naturalist Johann Jakob Kaup described the square-tailed kite in 1847.
The square-tailed kite is monomorphic with no recorded geographic variations.
As an adult the square-tailed kite is a medium-sized raptor, with the following features:
As an adult, the squared-tailed kite has a white face, with pale eyes and black streaks across the crown. The breast is also heavily streaked. The ventral surface of the wings has a rufous-brown lining, a dark carpal crescent, and a boldly barred finger. There is also a pale white patch on the ventral surface of the wings, at the base of the primary feathers; the saddle, rump and central upper tail-coverts are blackish, while the upper tail-coverts are grey-brown and fade into a small pale patch above the tail. The tail itself is square with dark sub-terminal band. Square-tailed kites also have a black bill, with a pink base and cere, and short legs and feet which are whitish or cream.
This species does not experience seasonal changes to the colouration of its plumage nor is the species sexual dimorphic. Juveniles are easily distinguished from adults by the lack of the white face and their richer rufous colouration (on both the head and the body). They are also significantly less streaked than adults.
Square-tailed kites can be confused with a range of other similar sized kites and raptors. The white face and shape of the tail, as well as the overall size of the bird, are considered diagnostic features in such cases
The square-tailed kite is a specialised canopy-dwelling predator, and can be found in a number of different habitats including open and temperate forests, woodlands, scrub, heathland, riverine trees, and savannah. Square-tailed kites can also be found in well-vegetated urban areas such as golf courses and parks. They are seldom found on the ground.
