Field Marks and Identifying Characteristics: |
Heard a flock of Chickadees foraging in the tree tops, so I started
trying to pish them out and look for tag-a-longs, then noticed a tiny
warbler with them, noted its overall very pale lemon yellow upper parts
and breast fading to a pale whitish yellow belly, and white undertail
coverts. Also noted its very thin fine pointed bill and short tail, had
a faint supercilium and eyeline but hard to see above us. Later an
Audubon's Warbler and 2 Orange-crowned joined it, which made it harder
to keep track of but offered direct comparisons with Orange-crowned
which were brighter yellow, had grayish heads and longer tails. Watched
them for some time and got excellent looks at both TEWA and OCWA. (see photos) |
| Song or call & method of delivery: | None heard |
| Behavior: | Foraging in the top of an Elm |
| Habitat: | Mixed of cultivated conifer and deciduous trees in a City park near a large pond |
| Similar
species and
how were they eliminated: |
Orange-crowned Warbler-very similar but always have yellow undertail coverts, overall more greenish yellow,
often with a gray head in fall(depending on ssp.), a little larger and
longer tailed. Direct comparison Yellow Warbler(female)-larger and longer tailed, often brighter yellow(but variable), longer flatter bill, eyering Warbling/Philadelphia Vireos-larger and longer tailed with bigger bill and more olive greenish color |
| Previous
experience with this & similar species: |
Yes, many in Colombia, several in Texas, 1 in Mexico and my 4th in Utah. Countless OCWA,YEWA and WAVI |
