(Description:)
Field Marks and Identifying Characteristics: |
Appeared smaller and more compact than nearby Yellow Warbler. Overall rather drab colored bird, white underneath and appeared generally blue-gray above, with small sharp bill. As the back did not appear to be very green at first, I assumed this was a Lucy's Warbler. However, there was no rusty color on the head nor rump. Further views showed the face was light gray with a white supercilium and also white below the eye. Subsequent views showed some green in the back, but without strong contrast to the gray head. Good views showed the entire underside of the bird was white, including the undertail. |
| Song or call & method of delivery: | Did not vocalize. |
| Behavior: | Actively foraging in mid to upper parts of Russian Olive and Cottonwood trees. |
| Habitat: | Generally open grass/reeds interspersed with Russian Olive and Cottonwood trees. |
| Similar
species and
how were they eliminated: |
Distinguished from Vireos by smaller size and thinner, pointed bill. Distinguished from Orange-crowned Warbler by completely white undertail. |
| Previous
experience with this & similar species: |
Seen once previously in Utah, several times in California. |
