[mou] Black-throated Blue Warblers: Cook County

[Michael Steffes]

On Friday, I had 5-6 singing atop Oberg Mountain in Cook County.  Of 
interest one had the unusual song.  These numbers would be expected 
at this time of year.  More Black-throated Blue Warblers singing that 
Black-throated Green Warblers.

I thought I would report on Lake County numbers to report with those 
of Cook County, but it has been so cold here (snow flurries this 
morning), and windy I did not walk the trails.  Hope to be out in 
Tettegouche tomorrow.
