High Quality Content by WIKIPEDIA articles! The Lesser Yellow-headed Vulture, Cathartes burrovianus, 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 centimeters (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.
