Every year in the fall, I get to witness a really cool natural phenomenon right from my front yard. These are all vultures--both Turkey and Black Vultures-in a gathering also known as a vulture kettle. Its not what you might be thinking-these birds aren't all out looking for dead things to eat. Instead, they have searched out special features of the natural landscape...
The neighborhood I live in sits on top of a hill overlooking the Tennessee River. The wind currents lift off of the hillside creating thermal currents-or rising columns of air. The vultures seek out these thermal currents which lifts their bodies and allows the birds to soar effortlessly for hours. In the times that I've watched them I've seen very few wing flaps.

As the birds start decending from the sky they take up roost for the overnight in trees across the street from me--very tall trees on a hillside not close to any homes.

These are all Turkey Vultures, easily distinguished from Black Vultures by their underside wing patterns. With a wingspan of 69 inches (175cm) its quite an impressive bird and also a very valuable member of the ecosystem since they are part of the clean up crew that feeds on animals that have died.

Its really a delight to see these birds flying about and doing their thing. The only one around here that gets freaked out about them is my dog--I guess she thinks they're out to get her.
