This morning Debbie Terry and I hiked several miles of Gunpowder Falls in Baltimore County from a point between Prettyboy Dam and Falls Road down to Bunker Hill Road. We were targeting Cerulean Warblers for a later survey. Unfortunately we found none though the habitat remains suitable for most of this stretch of river. Birds that were present included:
Kingfisher  1
Hummingbird  1 heard, my first of the year
Pewee  1 heard
Acadian Flycatcher  3
Yellow-throated Vireo  6
Red-eyed Vireo  7
House Wren  1

Black-throated Green Warbler  3 heard
Prairie Warbler  1 heard at the powerline
Redstart  1 heard
Worm-eating Warbler  11, surprisingly the most numerous warbler
