Our bird feeders did a brisk business yesterday -- at one time I counted six male cardinals but could only get three in frame.
All of these were taken through not-very-clean double pane windows. But it was way too cold to stay outside. 
The suet feeders were popular with the woodpeckers -- Downy or Hairy, I'm not sure which this was. There was a handsome Red Bellied one too but he was quite shy.
There were juncos and goldfinches, wrens, sparrows, and blue jays, along with this distant crow.
