Most of the warblers that I encounter in the autumn are Yellow-rumped Warblers (Setophaga coronata). They always seem to be in motion, whether foraging in the trees or on the grass. During this time of the year, Yellow-rumped Warblers are a fairly nondescript mixture of gray and brown, highlighted by streaks of yellow under the upper portions of the wings. I captured these images during the last week or so during repeated visits to Occoquan Bay National Wildlife Refuge.
On rare occasions, as in the second photo below, I will get a glimpse of the patch of bright yellow on the “rump” that is responsible for this species’ common name. It also gives rise to a fairly common nickname among birders, who affectionately refer to Yellow-rumped Warblers as “butterbutts.” Unlike other warblers that merely pass through our area, Yellow-rumped Warblers tend to hang around for longer and I will sometimes see them during the early days of winter.
