The nest of the turkey vulture is usually found on a cliff, on the ground in caves, crevices, in mammal burrows, in hollow trees, in thickets and in abandoned buildings. Adult females lay two cream colored eggs with brown spots on the larger end. Both parents sit on the eggs and the young are born forty days later.
Baby vultures feed on regurgitated food and are able to fly after about ten weeks. Turkey vultures are highly social animals and prefer to roost in large colonies in dead trees, cell phone towers, rooftops and porch coverings.

Theres a roosting area right at the top of Forest Drive/Aris T Allen Blvd and you'll see a bunch of vultures there in the morning and eve. They are more of a "roosting" type bird than a "nesting" type, so a nest is only used for the babies.
