We observed well over a hundred Turkey Vultures gathered on power line towers just south of Lake Lewisville near state highway 121. It was early in the morning, and the birds appear to be waiting for the sun’s warmth to create the columns of rising warm air, called thermals, that they need to help them glide in search of food.
