The gray-headed pygmy owl ( Glaucidium griseiceps ) or Yucatán pygmy owl is a small species of pygmy owl . The species occurs only in southern North America and Central America.
Appearance
The gray-headed dwarf owl reaches a body size of around 14 to 16 centimeters. The skull and neck are brown-gray, while the plumage on the upper side of the body is dark brown. There is a noticeable occipital face in the neck . The tail has two to three interrupted, whitish transverse bands. The underside of the body is whitish with reddish-brown spots on the chest and reddish-brown vertical stripes on the flanks.
In the distribution area of the gray-headed owl owl, there are several other pygmy owl species with which it can be confused. Both the Sanchez pygmy owl and the Colima pygmy owl have a larger number of cross bars on their tails. The gnome pygmy owl is larger and noticeably spotted on the back. The Brazilian pygmy owl is also larger than the gray-headed pygmy owl.
Distribution area and habitat
The distribution area of the gray-headed little owl is the southeast of Mexico and Central America to Panama. It is a resident bird that inhabits moist tropical evergreen forests as well as moist scrubland. It also occurs in abandoned plantations with older trees and in semi-open, shrubby regions. Its height distribution ranges from sea level to altitudes of 1,300 meters above sea level.
Way of life
The gray-headed pygmy owl is partly diurnal. Its diet consists of insects and small mammals, birds and other vertebrates. Very little is known about the breeding biology of this species.
