Dark-eyed Junco

The Dark-eyed Junco has two different subspecies.  Utah has the “Oregon” Junco sub-species, which I posted about recently.  Illinois has the “Slate-colored” Junco variety.

 

 

The difference is so huge, I don’t understand why they aren’t different species.  The “Oregon” Junco has a black head and a brown back.  These juncos are very gray.

 

 

Illinois appears to also have the “Oregon” variety because at the Baha’i House of Worship, the junco on the right is a female “Oregon” Junco.  The junco on the left is a male “Slate-backed” Junco.  You can tell that he’s male because the head color is closer to black than gray.
