As a side note, my feeders have been fairly active (for me, at least!) over the past little while - max numbers:
Dark-eyed Junco - 10+
Northern Cardinal - 3
Black-capped Chickadee - 5+
American Goldfinch - 2
House Finch - 2
House Sparrow - 2
Red-breasted Nuthatch - 1
Sharp-shinned Hawk - 2 individuals - neither managed to catch anything
Considering I just have a small hopper feeder and some seed spread on the deck, I'd say that's not too shabby!
Snowy Owl, 5 minutes from home!
