The gold-crowned yellow throat ( Geothlypis flavovelata ) is a small songbird from the genus of the yellow throats ( Geothlypis ) in the wood warbler family (Parulidae). It inhabits the northeast and central east of Mexico . Together with the willow yellow throat ( Geothlypis trichas ), the Bahamian yellow throat ( Geothlypis rostrata ) and the Belding yellow throat ( Geothlypis beldingi ), the yellow throated yellow throat forms a super species . The IUCN has listed them as "endangered" (vulnerable) since 2000.

features

female

Gold-crowned yellow throats reach a body length of 13 centimeters and weigh 10.2 to 11.5 grams. The wing length is 5.35 to 5.55 centimeters in the male and 5.1 to 5.45 centimeters in the female. Adult male gold-crowned yellow throats wear a striking black face mask that extends to the ear covers and is connected to one another above the crown of the forehead. Close behind it is a broad yellow to golden-yellow forehead crown band, which is significantly wider than other species of the genus Geothlypis , and extends to the sides of the neck and diagonally below the ear covers. The rest of the head plumage is yellow. The upper side plumage is yellow-olive; the underside plumage pale yellow with yellowish-olive washed flanks and sides of the chest. The beak is blackish; the legs flesh-colored.

The black face mask is missing in the females. The olive-yellow crown plumage is partially interspersed with washed-out brown tones. The ear covers and reins are olive to olive gray; the superciliar stripe , eye ring and the forehead crown light yellow to yellow. The neck is brownish-olive; the sides of the neck are paler and more yellow.

Occurrence, nutrition and reproduction

Gold-crowned yellow throats are endemic to the northeast and central-east of Mexico . They inhabit fresh water swamps and the bank edge areas of bodies of water with vegetation consisting of reed beds , usually cattails . For the most part, nothing is known about the breeding behavior and diet. Presumably, like all other yellow throats, they build a deep, bowl-shaped nest in the lower areas of the plants they inhabit and feed mainly on insects .

Hazard status and inventory figures

The IUCN has listed the species as "endangered" (vulnerable) since 2000 because of habitat destruction and heavily fragmented sites. There are records of the states of San Luis Potosí , Veracruz and Tamaulipas . No studies are available for other locations. The largest populations are in Laguna Champayán (Tamaulipas), in the northeast of El Naranjo (San Luis Potosí) and inland of Tecolutla (Veracruz). According to the bird protection organization BirdLife International , the population size is estimated at 2500 to 10,000 individuals.
