While we were in Yellowstone we spotted a bird that we are pretty familiar with back home except it looked a little bit different. The dark-eyed junco six different populations across North America that all look similar but have slight differences.
The first bird pictured is the one that we photographed in Yellowstone. I believe that this is the Oregon variety of the dark-eyed junco. The Oregon variety can be found in the western parts of the US and Canada. Birds that nest up in Canada usually winter in the western US including Wyoming and Montana, where Yellowstone is located. The second bird pictured was photographed at White Water State Park, located in southern Minnesota, in February. This is the slate-colored dark-eyed junco that can be found through out most of the US during the winter. This is the type of junco that we see around southern Minnesota in the winter.
