We were also there Sep 25-27, and waded out to Gull Island on Sunday and Monday.
Highlights were a Red-necked Phalarope (Gull Island), Eared-Grebe (very far out), several Merlins and Peregrine falcons, a dozen Black-bellied Plovers + 1 Am-Golden Plover, Lapland Longspurs (Gull Island).
We did find pockets of warblers in the lighthouse area.
