Dark-eyed Juncos in CT

Male Slate-colored Junco

Likely a young male Slate-colored Junco

Dark-eyed Juncos are common throughout Canada and the United States. Also called DEJU by birders who use alpha codes. The only common DEJU is the typical Slate-colored Junco (SCJU). Juncos are highly variable in plumage, which makes identifying different rare subspecies in Connecticut hard. So virtually all the juncos you see will be Slate-colored Juncos (Junco hyemalis ssp. hyemalis), any rare subspecies would need a good photo and good details.
Juncos are commonly found in suburban habitats. The highest count of Dark-eyed Juncos at my feeders is 16.
                                                                       Rare subspecies:
There have been multiple reports of Oregon Junco in Connecticut (according to the maps on eBird). And one report of the Cassiar Junco (J.h. cissmontanus). Cassiar junco shows both characteristics of Oregon and Slate-colored Juncos. If you think you saw a Oregon or Cassiar Junco I would like to know!  Also check out this article on junco ID!: www.oceanwanderers.com/JuncoID.html
