Why did the vultures chose to land there? A roadkill mammal (probably what was once a groundhog) was on the far side of the road. With small carcasses, they each wait their turn, according to a clear pecking order.
Vultures circle about the fields around here all the time. They are particularly jubilant about hay mowing, since the blades usually whack a few rabbits on every field. I've learned to not feel too creeped out by having them circle overhead from time to time. But at least one or two are visible from my front porch, their broad wings riding the air currents nearly every day.
At certain times of the year, a dozen or more vultures can be seen squabbling out in the pastures. With the larger numbers, the turkey vultures are often accompanied by one or two black vultures. The latter have a poorer sense of smell, so they follow the turkey buzzards to the dinner table.
