I have no experience with Birdcast but I had multiple Warbling Vireos and W
Wood Pewees at every park I visited yesterday afternoon along the coast,
while Claremont (50 miles from the ocean) continues to have little to no
migrants. I didn’t even take binoculars with me when I walked Duke early
this morning.
