Besides my earlier reported yard Pine Siskin, I saw more siskins today 
at yard feeders at intersection of Whites Ferry Rd/Trundle Rd and also 
at White's Ferry Rd/Martinsburg Rd. The latter location also had a 
couple male Purple Finch.

At the Poolesville Public Works Lagoon (adjacent to LM Stevens Park), 
there was a male  Northern Pintail mixed in with the Mallards.
