Field Marks and Identifying Characteristics: |
Small wren with a very short, upright, and finely banded tail. Upperparts mostly
brownish with small whitish flecks along the shoulders, flanks, and wings
becoming more extensive behind the auriculars. Throat, breast, and supercilium
were beige/buffy in color and contrasted with the upperparts. (see photos) |
Song or call & method of delivery: | Called frequently with a low "chup" or "chup chup". Initially located by voice which sounded somewhat like a song sparrow. Also gave a longer, harsher scolding call after a small flock of western scrub-jays flew nearby. |
Behavior: | Very active, flitting in and out of marshy vegetation and piles of dead branches. It rarely stayed in one spot more than a few seconds at a time. Calling most of the time. At one point the bird flew across the creek and under a large log where it stayed out of sight for about one minute. |
Habitat: | Riparian marsh with willow and cottonwoods nearby. Pinyon-juniper surrounding the general area. |
Similar
species and
how were they eliminated: |
This wren had a lighter throat and supercilium when compared to the pacific wren's more rufous throat. This bird also had more white flecks throughout the upperparts than a pacific wren. Call notes were also lower than pacific (I was able to reference both species calls on my phone while on site for a direct comparison). |
Previous
experience with this & similar species: |
The only "true" winter wrens I've seen were when I lived in North Carolina about ten years ago. I have seen or heard several Pacific wrens in Montana, Utah, Idaho, and Oregon. However, I have not had many opportunities to scrutinize these species since the split. |
