Population Estimate: 20M
Range / Habitat: Year-round through the southwestern US and throughout Mexico. Preferred habitat is high altitude grassland, shrubland, and forest.
Field Notes: Distinctive plumage as above. Typical Junco behavior: found in groups foraging on the ground then will make a hasty retreat to higher perches. Distinctive fan-like tail in flight with white-flashes on the sides. There are similar-colored variations of Dark-eyed Junco, but the eye color is determinant. Also, per Sibley, the dark-eyed varieties hop on the ground whereas the yellow-eyed birds walk.
Personal Notes: We were more than happy to take a break from summiting Xinantecatl in central Mexico to observe these birds.
