- Vireo flavoviridis
Identification
14–14.7 cm(5.5-5.75 in)
- 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 the extreme south of Texas (Rio Grande Valley) to central Panama, mostly migrant with wintering grounds from Colombia and Venezuela south through Peru, to western Brazil and Bolivia. A few are probably present during any month in Panama4.
Taxonomy
Yellow-green Vireo was in the past 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
Subspecies insulanus is included within flavoviridis by some authors while perplexus has been proposed as a new subspecies5.
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
Vocalizations
Song is often repeated and consists most often of two syllables per phrase put together in a hesitant series with a few single syllable phrases. The song is more monotonous than Red-eyed Vireo, and contains chirps that make some observers think of House Sparrow. This bird can sing all day.
Calls range from raspy to mewing, often with a nasal quality.
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.
