It was -1F/-18C when I ran into a group of small birds making their way through the pine and fir above Kamloops. It was a mixed flock of Black-capped Chickadee, mountain Chickadee, Brown Creeper and Red-breasted Nuthatch. I find it amazing that these tiny little birds can survive the major sub 0 temps with a limited source of food. From what I have researched, to make sure they dont freeze overnight, the enitre flock finds a woodpecker hole and piles in on top of each other and vibrate all night to make sure they don't freeze.
