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 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.
The lesser yellow-headed vulture feeds on carrion and locates carcasses by sight and by smell, an ability which is rare in birds. It is dependent on larger vultures, such as the king vulture, to open the hides of larger animal carcasses as its bill is not strong enough to do this. Like other New World vultures, the lesser yellow-headed vulture utilizes thermals to stay aloft with minimal effort. It lays its eggs on flat surfaces, such as the floors of caves, or in the hollows of stumps. It feeds its young by regurgitation... Wikipedia →

Rare
Under 5% of wildlife watchers report a Lesser Yellow-headed Vulture sighting in Bogota on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 172nd most-seen of the 231 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Lesser Yellow-headed Vulture in Bogota on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Lesser Yellow-headed Vulture sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
16th of 18
Of the 18 cities where we can rate Lesser Yellow-headed Vulture sightings, Bogota ranks 16th at under 5%. The best odds are in Barranquilla (Colombia, about 30%), São Luís (Brazil, about 20%) and Recife (Brazil, about 10%).
GBIF citizen-science records
It is estimated from how often the Lesser Yellow-headed Vulture is recorded against all the birds logged in Bogota (25 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
