Things have gotten a lot quieter at Halethorpe, but there was still enough 
activity this morning to keep it interesting. An ALDER FLYCATCHER was seen and 
heard behind the always-birdy small pond, singing robustly with a classic 
"reee-beea" and calling with its "pip" notes. There were also a number of Acadians 
in the area. Willow Flycatchers seem to pass through here in mid-May but as 
far as I know they don't stay.

10 species of warbler were seen or heard. Most were the common residents, but 
also notable were one singing BLACK-THROATED BLUE, about 6 BLACKPOLL's, one 
NORTHERN WATERTHRUSH and 2 CANADA's -- one male and one female. The biggest 
surprise was a silent male PROTHONOTARY along the back edge of the small pond. 
I'm not sure where this bird came from -- it seems late to be a migrant, but 
I've not seen or heard one here this spring until today.
