[Maine-birds] Shorebirds and Gulls at Biddeford

Mark Rolerson and I had a good day in Biddeford today, Monday, Sept. 16, 2024. the highlight was one Western Sandpiper on South Point. 

At South Point Sanctuary a half hour after high tide, we saw a large flock of shorebirds frantically feeding in the mounds of wrack right at the waterline. 

Rough estimates:

Semipalmated Sandpipers  250

Semipalmated Plovers 150

Sanderlings 50

White rumped Sandpipers 10

Least Sandpipers 5

Dunlin 5

Black Bellied Plover 2

Western Sandpiper 1 (much longer bill than surrounding semipalmated sandpipers with slight droop at tip, rufous V on upper scapulars contrasting with gray lower scapulars)

Three hours after high tide at Hills Beach and the Basket Island Causeway we saw the following:

Many Herring, Great Black Backed and Ring Billed Gulls

Black Bellied Plover 50

Dowitcher sp (probably short billed) 40

Red Knot (immatures with scaly scapulars) 20 

Lesser Black Backed Gulls  7 (adult)

Dunlin 1
