Identifying Characteristics:
It looked round and had a short bill and a tail about the length of its undertail coverts. It might have had a tinge of yellow to its throat but looked dull overall with a wash of yellow on its breast. The face pattern was contrasty and the white was strongest around its eyes; forming semicircles above and below.

Song or call & method of delivery: quiet
Behavior: It moved around a lot in thick cover and was seen best when it stopped to eat a green caterpillar on its twig.
Habitat: Thick and brushy, alder I think, on a small hillside. The creek was on the other side of the trail.
Similar species and how
were they eliminated:
I guessed it might be Philadelphia because it looked rounder than the Warblings I saw. It looked more yellowish under than the warblings I saw in similar shade. It had a little yellow on its breast and white/very pale yellow on its undertail coverts and belly. Its face looked more contrasty and dark, and had shorter round eyebrows and short triangular lores so its head looked less long. Its back was darker and its forehead may have been slightly darker.I have very little experience with this species.
