Brutally Cold! How do birds survive at MINUS-38F? Sax-Zim Bog Minnesota Virtually Live 24

How do birds survive at Minus-40 F?? On this BRUTALLY COLD episode of Virtually Live Sparky will share some tricks our boreal birds use to not only SURVIVE, but THRIVE in these temperatures.

He films and shares winter natural history for White-winged Crossbills (3,000 seeds per day!), Common Redpolls (a metabolism trick "down their throat"), Pine Grosbeaks, Sharp-tailed Grouse (warmer in the subnivean world!) and Great Gray Owl (super powers of hearing).

Witness the incredible sounds of spruces "popping" at Minus-38 degrees when the first rays of sun hit them and their cells explode.

Sparky also visits our NEW LITTLE FREE LIBRARY at the Bob Russell Bogwalk at Winterberry Bog and finds some interesting titles!
