Turkey Vulture Kettle - Callville Bay Picknic area - Lake Mead, NV

During the mid day we rarely saw a couple of Turkey Vultures, but...

Each evening the Turkey Vultures would soar overhead, at first just a couple would come into the area.

Then a few more 

then more and more would join.

It was mesmerizing to watch them soar, how they never hit eachother is amazing, since there seems no order to their movements other than riding the wave of the wind. 

Here is a video: on this evening Suzi counted at least 30 in flight. 

The next evening while there were still some Turkey Vultures coming back to their tree, the numbers were dramatically lower.

  

We took it as a sign to head north ourselves.
