Vireo flavoviridis
Photo by Peter Withers
Yucatán, Mexico, July 2008

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

Juveniles

  • Duller
  • Brown eyes
  • Brown tint to the back
  • Less yellow on the underparts

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.

Taxonomy

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

Subspecies

There are 3 subspecies[1]:

  • V. f. flavoviridis:
  • V. f. forreri:
  • Western Mexico (Sonora to Jalisco) and Tres Marías Islands
  • V. f. insulanus:
  • Pearl Islands (Gulf of Panama); winters to upper Amazonia

Others recognize more subspecies: flavoviridis, forreri, and insulanus by Restall2 or not insulanus but instead perplexus in Avibase (probably from Dickinson3).

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.

Behaviour

Breeding

The female builds a cup shaped nest from plant materials. The clutch consists of 2-3 white eggs with brown marks, which are incubated by the female. Both adults feed the young.

Diet

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