Paul, In my experience, in the proper habitat, they (Acadian Flycatchers) can be "common" (found on every field trip) around here. Not in great numbers mind you, but still not what I would call difficult to find. Perhaps this is ANS's way of warning us about a birds vulnerability because of loss of habitat before it becomes truely scarce? I think the Montgomery county checklist still lists it as common for this season, though I don't have the checklist in front of me... Rick Sussman Warblerick@aol.com
