Similar species

Within its range, most like Mountain Chickadee, which overlaps in a small area of central Arizona.

A striking example of convergent evolution can be found in Crested Tit (from Europe), which differs only in the more extensive black freckling on the face.


North America, in Arizona, New Mexico in the USA, and widespread in Mexico.



There are 4 subspecies[1]:

  • B. w. vandevenderi:
  • B. w. phillipsi:
  • Southeastern Arizona (south of Gila River) to northwestern Mexico (Chihuahua, Sonora, Sinaloa, Durango)
  • B. w. wollweberi:
  • Central and southern highlands of Mexico (Durango to Nuevo León)
  • B. w. caliginosus:
  • Western Mexico (Sierra Madre del Sur of Guerrero and Oaxaca)

A fifth subspecies annexus, is generally considered invalid[2].


Mixed oak, pine and juniper woods, in forested mountains; most often observered at altitudes of 1,000-3,000 meters, but sometimes as low as 560 meters in Oaxaca. More rarely, in riparian willow and other scrub on desert fringes, particularly in winter.



They nest in a hole in a tree, lining the nest with soft materials.


The diet includes caterpillars, seeds, nuts and berries.


Song: whistled pidi-pidi-pidi-pidi.
