features
Nelson yellow throats reach a body length of 13 centimeters and weigh 10.1 to 11.8 grams. The wing length is 5.2 to 6.1 centimeters in the male and 5.2 to 5.7 centimeters in the female. Adult male Nelson yellow throats of the nominate form wear a striking black face mask and a medium gray adjoining forehead crown stripe that extends to the sides of the neck and the ear covers. The crown, neck, side and upper side plumage is dull olive; the tail feathers a little dull olive. The wings are brown with olive feather edges. The underside plumage is yellow with faded olive flanks. Adult females have olive crown, head side and top side plumage and a medium gray superciliar stripe and a pale olive eye ring.
Occurrence, nutrition and reproduction
Nelson's yellow throats are endemic to Mexico . They inhabit dense undergrowth and shrubbery on the highlands at altitudes of 1,800 to 3,100 meters and feed mainly on insects and other invertebrates that they find in the lower areas of the vegetation . No details are known about the breeding period, nest building, incubation and nestling times. Adult males with food in their beak were sighted from May to July. Presumably, like other yellow throat species, they create a deep, bowl-shaped nest.
