Goose in a Tree

I went back to Whitaker Ponds this morning, this time with Eric.
I don’t know what this goose is doing in the tree, does anyone? We were a ways from here, when suddenly there was a loud ruckus of honking and wings flapping, when I looked, a pair of geese seemed to have headed right into that snag where the one is sitting. They disturbed a few crows, who added to the din, and it took awhile for the goose to find purchase. I thought maybe the geese ran into the tree by mistake; they sure made a hell of noise. The other kept going, but as we watched, waiting to see what would happen to this one, it flew off - then returned! And sat there until we moved on, tired of waiting for more action.
