|
Description: |
I first briefly passed it off as a Red-eyed Vireo, but the beak looked especially large. At second glace, indeed the beak was quite large and I continued to watch the bird carefully, then noticing the malar streaks when the head was at the correct angle. The malar streaks did not seem to jump out at me as much as a bird I found on Grand Isle last spring, but they were still obvious enough to be seen clearly, even 10 m away. |
|
Voice: |
None heard |
|
Similar
species: |
Red-eyed Vireo was quickly eliminated due to the large bill and then the distinct malar streaks. |
