DESCRIPTION:
A fairly small bird of prey commonly seen sitting on the back of cattle or other mammals and taking ticks from them.

Yellow-headed Caracara has dark brown to blackish upperparts. Back and wings are blackish brown. Long wings show large whitish patch at base of outer primaries, very conspicuous in flight.
Buff tail is fairly long and rounded. Uppertail coverts are buff with numerous narrow wavy dusky bars, broad blackish subterminal bar and fine whitish terminal band.

Underparts are pale buff to creamy-white. Underwing shows buffy to creamy-white coverts and blackish-brown flight feathers. Undertail has similar pattern as uppertail.

Head and neck are pale buff to creamy-white, with blackish stripe behind the eye. Lores, base of the bill and eye-ring are bare and yellow, but sometimes they are paler.
Hooked strong bill is horn-coloured. Eyes are reddish-brown. Legs and feet are pale greenish-grey.

Both sexes are similar, with female slightly larger than male.

PROTECTION / THREATS / STATUS:
Yellow-headed Caracara is widespread and common. This species has probably benefited from deforestation for cattle or farming. It is usually seen in urban areas in Latin American cities.

Yellow-headed Caracara often perches at treetops in small groups. It also patrols along roads and rivers, searching for dead animals, and it follows the ploughs in order to catch the small disturbed animals.
Outside the breeding season, they gather at night-time communal roosts where they spend the night together. They leave the place early in the morning for hunting.
During the breeding season, yellow-headed Caracara becomes more aggressive against rivals, and defends strongly its territory.

VOICE: SOUNDS BY XENO-CANTO
Yellow-headed Caracara utters typical screams “schreee”, some growling “kraa-kraa-kraa”, and thin, hissing whistles.

HABITAT:
Yellow-headed Caracara frequents open areas with some trees, cultivated areas, pastures, swamps, forest edges and along streams. It is found from sea-level up to 1800 metres of elevation, and locally up to 2600 metres, and recently 3600 metres in Ecuador.

RANGE:
Yellow-headed Caracara is resident in South America, from Costa Rica, Trinidad and Tobago, and southwards to northern Argentina. Also found in Colombia, Venezuela, the Guianas, Brazil, Paraguay and Uruguay.

BEHAVIOUR:
Yellow-headed Caracara feeds on varied kinds of food, from carrion, road-kills, insects, amphibians, fish, birds, fruits of oil palms, maize and horse dung.
It forages by walking on the ground, but it is often seen perched on cattle’s back to take ticks and it also pick off flesh from open wounds.

FLIGHT:
Yellow-headed Caracara has buoyant flight. It alternates regular wing beats and occasional sweeping glides.

REPRODUCTION:
Breeding season varies according to the country.
Yellow-headed Caracara builds a large nest with sticks. It is usually situated high in tree, and particularly in palm tree. But it may also nest on mounds in marshes, or on the ground in pampas.

Female lays 1 to 2 buffy eggs with brown markings. Nesting behaviour is unknown, but usually in Falconidae, incubation lasts about one month, and young leave the nest at about 40 days of age. 

DIET:
Yellow-headed Caracara is omnivorous. It feeds on carrion, dead animals and even dead crocodiles and anacondas. It takes road kills, insects and caterpillars, amphibians, small birds, and fish. It also consumes the fruits of the oil palm Elaeis, maize and horse dung.
It is well known for picking off ticks from cattle, and it is often seen perched on their back.
