The Black-eared Kite is a medium-sized bird of prey, measuring about 45–55 centimeters in length with a wingspan of up to 150 centimeters. The distinguishing feature of this subspecies is the black patch of feathers on the sides of the head, located behind the eyes, which gives it its name. Its eyes are dark brown, its bill is short and hooked. The outer wing feathers are black, and the feathers have dark crossbars and a mottled base. The underparts are pale brown and become lighter towards the chin. The body feathers have a dark shaft, giving it a striped appearance. The corner of the mouth is yellow, but the bill is black. Male and female birds look the same, but females are slightly longer with a larger wingspan.

Black-eared Kites are opportunistic hunters and feed on various prey such as small mammals, birds, insects, and reptiles. They are often seen soaring high in the air on thermal updrafts, effortlessly gliding while searching for potential prey on the ground.
