Duration of

Approximately 1 minute |
|
Habitat: |
Vireo located in a small live oak (Quercus virginiana) next to a substantial patch of cane |
|
Behavior of bird:
|
The vireo flew into view from the live oaks adjacent to the cane, and once in view the vireo sat still on the live oak branch for approximately 1 minute, where I was able to see the diagnostic features of V. altiloquus. After this brief encounter, the BWVI retreated in the direction in which it had appeared. Main reason for losing tract of the BWVI was in an attempt to summon other observers not too far from the location. |
|
Description:
|
At first a larger vireo sp. flew into view, and once perched, the black malar stripes were visible along with a considerably bulky bill in relation to the head. Other less distinct characters included a pale olive-green back, off-white underparts with olive tinged flanks, red irides, and a strong contrasting black and white supercilium. |

Voice: |
No voice heard |

Similar
