I had the good fortune of a wood-pewee showing up outside my office window this morning (3085 Center Green Drive, northeast Boulder). Took some poor digibinned photos (in linked checklist below).
I found this bird to lean more towards Eastern than Western Wood-pewee. Because this is an immature bird, I am hesitant of the colorations since it is a hatch-year bird. - Strong buffy wingbars of equivalent brightness to each other. - Long primaries compared to tail. - Coloration of back and head seemed more brownish (dirty) than grayish (rather than ashy). - Vested look is much more like Olive-sided Flycatcher than the washed out Western Wood-pewee I am used to. This individual showed a distinct open-vested look with an obvious white stripe down its chest. - When viewed from below, the undertail coverts seemed more yellowy, and less smudged than I have seen previously with Western Wood-pewee. - Maxilla dark. - Mostly yellow mandible (70-80%). - Eyering. - Crested look at times. - No tail flicking. Bird still present as of 11:10am. Along the railroad tracks west of Center Green 2 (3085 Center Green Drive). Here is my eBird checklist if anyone needs to see the photos. https://ebird.org/view/checklist/S48866030 Feel free to refute this claim as well as this would be a first for me in terms of differentiating. Seen plenty of both species, just never found one in the "others territory".
