Notes:  Most of January was very cold - too much so for us to attempt any banding.  Temperatures have warmed up nicely this week, and finally on Sunday both weather and time availability coincided to allow us our first banding opportunity of 2005.  Not surprisingly, the first bird caught was a Black-capped Chickadee.  However, we did also catch half a dozen unbanded chickadees, suggesting that the flock has changed somewhat in composition since our last banding efforts before Christmas, when it seemed that the vast majority of the local birds had been banded.  Rounding out the birds banded today were small numbers of American Goldfinch, Slate-coloured Junco, American Tree Sparrow, and Blue Jay.  The highlight of the day was a brief glimpse of a Pine Grosbeak in the trees behind the feeders - our 136th species for the site.  Also of note, a Brown Creeper in the woods north of the cabin, a Deer Mouse under the feeders, and the distinct tooth-marks on our birdseed bin of a mystery rodent.
