    Description of Habitat

One of several warbler species in tree canopy foraging along with Northern Parula, American Redstart, and Black-throated Green Warblers. Also seen or heard that location Tufted Titmouse, White-breasted Nuthatch, Northern Cardinal, and Blue Jay.

    Foraging persistently in upper and canopy along with the other warblers.

    Description of Vocalizations


    Verbal Narrative & Description of Observation

    Dull yellow to olive warbler, dim streaks on breast, yellow undertail coverts. Unpatterned and unmarked back and wings just a tad duller/duskier than face and underbody. Seemed to have an eyeline; face otherwise unmarked. Silent. (Described into a hand-held recorder at the time of observation by Worley)

    Relative Size & Shape

    Typical of canopy wood warblers. Was seen in close proximity to the other warblers.


    Noticeably unmarked except for eyeline.

    Feet & Bill

    Feet unseen. Bill characteristic of warblers, not thick as per vireos.

    Upper Back

    Dull yellow to olive, unpatterned and unmarked.

    Lower Back & Rump

    Dull yellow to olive, unpatterned and unmarked. Rump not seen but fleetingly.


    Wings just a tad duller/duskier than face and underbody. Characteristically warbler in size.

    Breast, Belly, Flanks, Under Tail Coverts

    Dull yellow to olive, dim streaks on breast, yellow undertail coverts


    Not seen with detail.

    IMPORTANT: What similar species were eliminated when making the identification and how was this bird different?

    Other warbler species with contrasting yellow undertail coverts: Nashville Wabler shows evident eyering. Common Yellowthroat has bright yellow throat. Palm Warbler has well marked face, bobs tail, and likely would show some rufous coloring this time of year.

    Other plain warblers, dull and not brightly colored, with dim breast streaks: Some Tennessee Warblers, but they never have contrasting yellow undertail coverts. Likewise, a similar, late, winter plumaged Cape May Warbler would have white undertail coverts.

    Other Notes & Comments

    When the bird was finally seen well by Worley, there was no hesitation in calling it an Orange-crowned Warbler.
