features

Gray-throated wood warbler reach a body length of 14 centimeters. The wing length is 6.5 to 7.06 centimeters in the males, 6.24 to 6.5 centimeters in the females. Adult birds of the nominate form and young birds from the first year onwards have broad blackish-gray side stripes on the crown that run to the neck, a lemon-yellow narrow stripe on the crown and a blackish-gray forehead. The central neck plumage, the sides of the neck, the ear covers and the reins are medium gray. The upper side plumage is dark olive green, slightly lighter at the rump , and the wings dark brown with dull olive green feather edges. The throat is grayish white, the upper breast plumage gray and the rest of the underside plumage dull yellow with olive-washed flanks. The tail is dull olive-green, the bill is blackish brown and the legs are yellowish-flesh-colored.

Occurrence, nutrition and reproduction

Little is known about the gray-throated wood warbler. The birds are found in northeastern Colombia ( Norte de Santander near the border with Venezuela and south to Cundinamarca and the west of Meta ) and in the Andes in the far northwest of Venezuela ( Mérida and Táchira ). They also used to settle in areas in the Sierra de Perijá on the border between Colombia and Venezuela, but have migrated due to habitat loss. They inhabit levels of vegetation in the middle and high mountains and forest edges with untouched undergrowth at heights of 800 to 2100 meters. They look for their food in the thick undergrowth. They are apparently quite creeping and difficult to observe. There are no studies on the breeding season or the incubation and nestling times.

Systematics

There are three recognized subspecies:

  • Myiothlypis c. cinereicollis P.L.Sclater , 1864 - Occurs in the Bogotá region in Colombia to the northeast (Norte de Santander).
  • Myiothlypis c. pallidula Wetmore , 1941 - Occurs in the Andes of Venezuela (Mérida and Táchira). The subspecies resembles the nominate form; the plumage is paler overall.
  • Myiothlypis c. zuliensis Aveledo & Perez , 1994
