Location: Yucatán, Mexico

[edit] Identification

14–14.7 cm. Olive-green upperparts, dusky-edged grey crown, dark line from the bill to the red-brown eyes, white supercilium, white underparts, yellow breast sides and flanks. Young birds are duller with brown eyes, a brown tint to the back, and less yellow on the underparts.

[edit] Distribution

Breeds from Mexico and Texas to central Panama, mostly migrant with wintering grounds from Colombia and Venezuela south to Brazil and Bolivia. A few are probably present during any month in Panama⁴.

[edit] Taxonomy

This species is considered a monotypic species by Clements¹ while others recognize more subspecies: flavoviridis, forreri, and insulanus by Restall² or not insulanus but instead perplexus in Avibase (probably from Dickinson³).

Yellow-green Vireo was for a while considered conspecific with Red-eyed Vireo.

[edit] Habitat

Seems plastic in its habitat choice, mostly in open and semiopen areas when breeding in Panama⁴ but more in forest and semiopen areas in South America during winter².

[edit] Behaviour

The female builds a cup shaped nest from plant materials. 2-3 brown-marked white eggs are laid and incubated by the female alone; the male helps to feed the young.

The diet includes insects gleaned from tree foliage, especially caterpillars and beetles, also small fruits, including mistletoe berries.
