The lesser yellow-headed vulture also known as the savannah vulture, is a species of bird in the New World vulture family Cathartidae. It was considered to be the same species as the greater yellow-headed vulture until they were split in 1964. It is found in Mexico, Central America, and South America in seasonally wet or flooded lowland grassland, swamps, and heavily degraded former forest. It is a large bird, with a wingspan of 150–165 cm (59–65 in). The body plumage is black, and the head and neck, which are featherless, are pale orange with red or blue areas. It lacks a syrinx, so therefore its vocalizations are limited to grunts or low hisses.
Region
Neotropics
Typical Environment
Occurs from eastern and southern Mexico through much of Central America and into northern and central South America, including the Llanos, Pantanal, and other seasonally flooded savannas. Favors open lowland habitats such as marshes, swamps, mangroves, wet grasslands, and cattle pastures with scattered trees. It avoids dense interior rainforest but uses edges, river corridors, and cleared lands. Common near wetlands that experience seasonal flooding and drawdowns, where stranded fish and small carcasses are frequent.

This New World vulture specializes in detecting carrion by smell, using a keen sense of olfaction to locate food hidden in grass or wetlands. It often arrives first at carcasses in open savannas and marshes, but yields to larger vultures once they appear. Lacking a syrinx, it can only produce hisses and grunts. It plays an important ecological role by rapidly removing carcasses and limiting disease spread.

Temperament
solitary and wary
Flight Pattern
soaring glider with wings held in a shallow dihedral; occasional short, rapid flaps and gentle rocking in wind
Social Behavior
Typically forages alone or in small numbers but may gather at abundant food sources and roost communally. Monogamous pairs nest in secluded spots on the ground, in dense vegetation, or in hollow stumps without constructing a true nest. Clutch is usually one to two eggs, and both adults share incubation and chick rearing.
Migratory Pattern
Resident
Song Description
Lacks a true song; vocalizations are limited to low grunts, snorts, and hisses at close range, especially around carrion or the nest. Generally silent while soaring.
