The Turkey Buzzards are Back

Our neighbor to the east has a huge cottonwood tree that is over 100 years old.  It grows partway down in Creamery Hollow just to the east of their house.  The tree is so tall that when the air is perfectly still on the ground, there is a wind draft in the top of this tree. Sometimes in the summer, we can see eagles circling.
 We are in the path of migrating turkey buzzards, and they often stop over to rest and fly in huge circles in the sky.  I ran to get my camera, but was not quick enough, and only four are in evidence in this picture. (A camera with better telescopic lens would do a better job, but this one gives you the general idea.)  Our neighbor tells us that in the early mornings, the birds are sitting hunched over, (Snoopy vulture style), waiting for their feathers to dry out so that they can fly.
