Not to worry, not that kind of stalker.
Along with hawks, we get the occasional vulture that flies over and checks out our yard.
Bear was in the backyard barking his fuzzy head off and I wondered what on earth it was this time. When I went out there, I saw this guy circling fairly low over our yard.
At first I thought it was a hawk, but then I saw from the face/beak it was a vulture/buzzard.
Since these lovely critters generally go after dead stuff, I wondered what it thought it saw, especially since it was flying fairly low.
I managed to get a few pictures of it before it flew away--I guess it either realized that there was nothing dead in our yard, or it saw I was taking snapshots of it. Not the most beautiful birds, but made for some interesting pictures, anyway. ;)
