Evidence of Brants, though no geese themselves, seen on their favorite pier this morning, just south of my bench. A pair of mallards flying upstream. Fifteen (!) Gadwalls a few piers north. And two mergansers fishing in the piling field. A gull dive-bombed them, as though he was worried they'd steal his breakfast. Since gulls don't dive for fish the way they do, he was likely just acting on bad-tempered principle.
