The Northern Beardless-tyrannulet is a rare species of tyrannulet found in the United States, as most of these birds live in South America. This would make it a special sighting indeed, should you be one of the few people to spot one in the Santa Rita Mountains south of Tucson.
This is a flycatcher, with a gray body and pale yellow stomach. The wings are darker gray than the body, with two pale bars and black streaks. Their beak is small and curved. Look for a bit of orange underneath the beak.
Hiking in the Santa Rita Mountains presents many wildlife viewing opportunities. From seeing this unusual bird, you will also have an opportunity to see many hummingbird and bird of prey species.
Each side of the Santa Ritas has different wildlife residents. The north side, and Madera Canyon, attracts birds that prefer riparian areas, while the west side tends to have more in the way of birds of prey and birds preferring wide open spaces.
