Normally, turkey vultures are seen roosting in trees and spend their time searching for carrion, soaring overhead in circles with wings upraised. This one was in a tree during the day, perhaps having spotted something below.

Actually, they are majestic birds in flight, sometimes mistaken for an eagle or osprey. According to 'All About Birds' https://www.allaboutbirds.org/guide/Turkey_Vulture/overview) -

"If you’ve gone looking for raptors on a clear day, your heart has probably leaped at the sight of a large, soaring bird in the distance– perhaps an eagle or osprey. But if it's soaring with its wings raised in a V and making wobbly circles, it's likely a Turkey Vulture. These birds ride thermals in the sky and use their keen sense of smell to find fresh carcasses. They are a consummate scavenger, cleaning up the countryside one bite of their sharply hooked bill at a time, and never mussing a feather on their bald heads."
