MD Ospreyers:

With the irruption of Black-capped Chickadees, birders should be alert for 
possible accompanying Boreal Chickadees.

 From the BNA-Online Boreal Chickadee account:
Irruptions [of Boreals] in New York, Massachusetts, and Ohio always 
associated with major southward movements of Black-capped Chickadees (Bull 
1974, Sorrie 1975, Peterjohn 1989), but not all irruptions of Black-capped 
Chickadees include Boreal Chickadees.

Black-cappeds are not reviewable, Boreals are, Carolinas are in the very 
western part of MD.
