As a farewell to Maryland birding for several months, i went and did  
a rigorous search of Soldier's Delight for migrants.
A solid day, sparse on migrating warblers though.
Highlights
20+ Prairie Warblers
1 Black-Throated Green Warbler
5 White Eyed Vireo
LEAST FLYCATCHER**

**This was a very difficult identification, but i'm confident in my  
call of Least:

Small Compact Flycatcher, contrasting belly and throat(opposed to  
similar belly and throat of yellow-bellied), though it did have some  
olive/yellow wash underneath which gave me pause. Strong contrast on  
wingbars
Vocalization: A sharp chbeck-chbeck-chbeck, in triplets, rather then  
a single piercing call like acadian. The notes were clear, not blurry  
like yellow-bellied.

Does this bird fall within reasonable migration dates?

Off to College
Good Birding
