With cold temperatures overnight, -23c, the bird activity at my feeders was great this morning. At sunrise a small flock of American Goldfinch were at the Niger Feeder followed by a couple of Black-capped Chickadee and White-breasted Nuthatch at the sunflower feeder and both Hairy and Downy Woodpecker at the suet. As the morning warmer up a bit a flock of 50+ Common Redpoll with one well marked Hoary Redpoll visited the feeder along with 3 Pine Siskin. All these species are erratic during winter months and it was nice to have them all at once.
It was interesting to watch the birds learn to feed at this feeder that I got in Arizona. The sack is filled with niger seed and the finches pull the seed out one by one. When I first put it up in August it took a couple of weeks before it had a following. The Black-capped chickadee was the first to figure out it was a source of food.
