The swallows were concentrated around the east skating pond, but were also flying quite a lot over the east peninsula.
Warblers are on the move too.
Near the east end of the peninsula there were several Yellow Warblers and 1 female Canada Warbler. A Mockingbird also perched in this area, as did a Phoebe. Despite the movement of migrants, there were still several signs of summer. In a similar vein, I noticed 3 female Common Goldeneyes on a tire in the first bay east of the parking lot. The shorebirds were the only disappointment this morning.
