Duration
of observation: |
1.25 hrs (non-continuous) |
|
Habitat:
|
Mature, disturbed coastal chenier woodlot. Live oak-honeylocust-hackberry dominated
woodlot with some herbaceous understory. |
|
Behavior
of bird: |
The vireo was observed in flight and feeding. It was actively foraging high in the
canopy of several large live oaks near LA-82. It moved quickly through the foliage and seldom perched out in
full view. On a few occasions, there
were interactions with REVI but otherwise it foraged alone. Much less cooperative than the Peveto
Beach Woods bird observed earlier. |
|
Description: |
A vireo with bright greenish-yellow upperparts and
extensive yellow wash on underparts, especially on sides, flanks, underwing
and undertail coverts. Grayish crown
blending with back and upperparts color.
Pale supercilium bordered by weak dark lines. Dark eye line. Greenish auriculars blended with yellow sides and whitish
throat. Large, pale horn bill. Dark red irides. Blackish tarsi and feet. |
|
Voice: |
A short series of liquid, vireo-like notes in
rapid succession. Scolding calls were
a soft, dry ‘rieh’, similar to REVI. |
|
Similar species: |
Very similar to Red-eyed Vireo (REVI) in
appearance, however Yellow-green Vireo (YGVI) is much brighter green-yellow
on upperparts and considerably more yellow on underparts (hardly any yellow
wash below on REVI). In addition, YGVI
has rather indistinct, blended head pattern (not bold as in REVI) and a much
larger, paler bill. Song unlike
REVI. No other similar N.A. vireos. |

about 3 mi. east). |
