Subject: [MDBirding] Harlequin Duck, North Beach, 2/28


Finally! Fred Fallon relocated the male Harlequin Duck yesterday morning and it was relocated by Joe Hanfman and Jeff Culler. I arrived shortly after 4 pm. I quickly found the HADU in a mixed scaup flock that angled diagonally northwest from Calvert waters into Anne Arundel waters. Where I had it was in an area that I'm not comfortable calling Calvert so I watched him swim further northwest until it was near the piers. It hung out there for a while then I lost it (the bird, not my sanity). After scanning back and forth for a about a half hour, I relocated it as it was swimming southeast. When I finally felt comfortable that it had moved south far enough into Calvert waters, and then some, I packed up.

There are many large scaup flocks in this area. I watched them diving and coming back up with what appeared to be clams. The Harley dove frequently, too, but I was never able to see it with anything in its bill when it surfaced.

Although Atlantic Avenue is clearly marked residents only parking, there is plenty of parking on 9th Street. I walked to the far northern end of Atlantic Avenue and scoped from the sidewalk.

Remember that this is a cartographic nightmare area. Depending on which map you look at, the AA/Calvert line varies. We hashed this out when the immature Yellow-crowned Night-heron was in the marsh�drainage. Depending on which side of the road it was lurking, it could be in either county. North Beach Marsh is solidly in Calvert. I believe we came to a resolution that the line angles 45� to the southeast at the Anne Arundel County line sign on the bridge. What the county line does once it enters the water is a good question. I'm assuming it doesn't angle southeast but proceeds due east? Does anyone know? I found this map that seems to back up that argument:

Anyway, a very cool bird that hasn't been reported in Calvert County since Marshall Iliff's 12/11/1990 probably in the same area, and Jim Stasz's 12/10/1985 bird at the Chesapeake Beach Marina. Why they're more regular at Pt. Lookout vs anywhere in Calvert, I don't have a clue!
