| Tree Swallow at Bison Paddock |
The little tree swallows seem to have bossed the slightly larger western bluebirds out of all the nest boxes. The only bluebirds I saw were feeding on the ground inside the paddock, then darting into thick brush when they sensed danger. Although they earlier appeared to challenge the swallows at the paddock nest boxes, their range map does not show them as breeding here in San Francisco (or anywhere along the coast). Maybe they don't have to compete with bossy tree swallows in their usual breeding range.

| I looked out our back window the other day and noticed an unusual grey blob in a neighbor's tree down the block. My wife thought it was a bird, but I'd never seen a bird on the outside of the crown of this tree before (scroll down the link). Binoculars revealed its true nature. |

| I don't know what kind of tree it is, but the squirrels were definitely eating something that grows on it. |
Squirrels in the Tree
The water bowl out back was disgusting, so I cleaned it out and put in fresh water. Half an hour later I happened to look down there again, and the bowl was already disgusting again. I put a trail camera on the bowl to see what was going on. Although the bowl didn't get as disgusting again for the next couple of days, I believe it was just a matter of luck -- that whatever they were dunking in the bowl wasn't quite as gross at that first day.
