|
Behavior
of bird: |
Wile observing the warbler frenzy near the
orange house, I noticed a non-warbler fly in. The bird landed in a Live Oak
on the south side of the "vetch patch" trail. |
|
Description: |
Instantly, I knew it was a Red-eyed type Vireo
and then I noticed a black malar stripe and moderately bright yellow
undertail coverts and flanks. While watching the bird forage at eye level and
even on the ground I became aware that the black malar stripe was much more
pronounced than the BWVI that I saw last year at this event in the Grilletta
tract. At almost first glimpse, I knew this vireo was different from Red-eyed
Vireos seen in the Sureway woods and Grilleta tract earlier that day and
weekend. I felt the bird was somewhat larger than a Red-eyed. The large bill and
malar stripe were the first plumage features that I looked for and confirmed
after noticing the larger bill. |
|
Voice: |
The vireo called briefly while foraging in the
Live Oaks towards the parking lot before it flew off to the west at 8:45am. |
|
Similar species: |
Differentiated from Red-eyed Vireo (Vireo
olivaceus) by large bill and very distinct black malar stripe |
