Raptors On Roost
Turkey vultures are normally seen gliding high overhead, soaring on thermal currents, those columns of rising warm air that enable them to cover miles while conserving energy at the same time. Last Wednesday I took these photos along the edge of an evergreen forest. Seven were roosting in a dead hardwood with several more situated in a splintered pine.
While a few birds flew back and forth between the edge of the pines and the dead tree, for the most part they were unalarmed, staying put for several photos.
Above photo depicts one turkey vulture spreading its wings while another preens its feathers. There is much speculation as to the reason for this practice. Some believe the wings are used as solar panels to generate body warmth while others tend to think they are utilizing the suns ultraviolet rays to kill bacteria picked up from diseased carcasses.
They are ominous-looking creatures, and with their featherless heads, turkey vultures may not be much in terms of appearance, yet they perform a valuable service by cleaning up carrion. Even from high overhead, the turkey vulture employs its keen sense of smell to locate food, one of the few birds of prey able to do so.
