Karl Overman: Birds and More

 
 

Checking a suburban Detroit park in late November I noticed a very odd chickadee--a “Brown-capped” Chickadee.  Even the back was brownish.  But no, it was not a sign of an every 50 year invasion  of Boreal Chickadee (Binford’s insight that we are due for since the last was 1972) but just a very aberrantly plumaged Black-capped Chickadee.
