On my way up the hill I heard several Scarlet Tanagers singing, and saw a large hawk, probably a Red-tail flying low through the trees as they began to thin near the top.
On the top, lots of Towhees, seemingly more Barn Swallows than usual, and a Sharp-shinned Hawk. The Sharp-shinned, which I guess is rare here this time of year, attracted all of the Swallows which were busy dive-bombing it as it flew in a straight line across the hill. It was an immature bird, brown all over.
I also saw a dead small snake (black with an orangey underside) that had apparently gotten its head stepped on on the path, and a very much alive, and oh so thick, huge black snake. Very shiny.
Some other birds I then came upon were a surprisingly large foraging flock of Grackles, and a singing Wood Thrush.
