Field Marks and Identifying Characteristics: |
Bird was foraging on the ground near the ranch house. Warbler had a complete eye
ring, two distinctive wing bars, bright yellow head and back. Bird seemed to
keep to itself though a Yellow-rumped Warbler briefly landed next to it giving a
size pattern. Bird also tended to hold its tail at a slight upward angle when
moving around. I was able to get five ok pictures with two different cameras. In
two of the pictures you can see a slight hint of the chestnut color on sides. I
believe the pictures have enough details to confirm this sighting. (see photos) |
| Song or call & method of delivery: | none |
| Behavior: | foraging around on ground, flying briefly to trees and fences |
| Habitat: | grass with large trees near by. |
| Similar
species and
how were they eliminated: |
Knew bird was a warbler due to shape and actions. I could not think of any warbler that was bright yellow backed, with complete eye ring and bars on wings so after getting pictures I looked in the Sibley bird guide app. on my phone. Bird looked like the first winter Chestnut-sided Warbler. |
