When I first started putting out cockatiel seed for the outdoor birds to eat, this little bird would join the sparrows. I could not identify him for the longest time because the vast majority of dark-eyed juncos are grey with white breasts (Slate-colored juncos). But finally, I realized that he was a dark-eyed junco. There are 15 different races of dark-eyed juncos and we have the Oregon variety. They're remarkably abundant during the spring and summer. Other than at feeders, I always see them on the forest floor.
You can see with the junco on the left that they have lovely silver tail feathers.The picture below is probably a female dark-eyed junco. The females are lighter in color. She was so obliging, just sitting there singing while I snapped pictures.
I tweaked this photo in Adobe Photoshop Lightroom. The junco was only a few feet away from us and I was using a long lens, so I needed the software to make the picture clearer and the leaves brighter.
