Our bird feeders are proving popular in this snowy weather with the most numerous species being Dark-eyed Junco. Up to now all that I had ever seen was the expected slate-coloured subspecies. Today however, I noticed an interesting junco that warranted further study. I attempted photos, but only managed one somewhat decent.
At quick glance it could be taken for a slate-coloured, but some features just don't match. Most obvious is the head is darker than the back and wings and the back itself is a reddish-brown.
After doing some research and sending an email to someone more experienced than I, it seems like this bird is most likely some sort of intergrade between Slate-coloured and Oregon subspecies. This remains a tentative identification as there seems to be a lot of variation within juncos. Anyone with additional input is welcome to comment.
An interesting find at the home feeders.
