    Observer’s Previous Acquaintance With This or Similar Species

    I am a biologist and birder from the west coast. I have been birding since I was a kid and know my
    west coast birds well, including several point count jobs, and have birded abroad in Australia, Peru,
    Mongolia, Thailand, and a few other places. However, that doesn't make me an expert with east
    coast birds. My experience with east coast warblers includes point counts in Virginia 2 summers ago
    for 3 months, some field work in Jamaica with warblers, and currently living in Pinkham Notch doing
    nature education for kids,where I've been watching the warblers there arrive. We had a program down
    in western massachusetts, and happened to be stopped, so I got out and started birding, which was
    when I saw the CONW. I have seen a lot of MacGilivray's warblers from the west coast, and was
    completely taken aback at how similar the bird I saw through my binoculars looked yesterday, except
    the eye ring was complete. I only had my phone with me, and although I was able to quickly double
    check my audubon bird app, see it was a vagrant, and get a second good look at the bird to verify, I
    didn't have any power to take a photo of it.

    I certify that that attachments included with this report were captured during this observation event​​.

    Sitting fluffed slightly for awhile calling, feeding a bit in the tree ~8 m off the ground, then moving on to

    Verbal Narrative & Description of Observation

    Sitting fluffed slightly for awhile calling, feeding a bit in the tree ~8 m off the ground, then moving on to
    trees in which I lost him.

    Relative Size & Shape

    Size of a typical warbler, bright yellow underneath with dark gray hood and complete eye ring. I am a
    birder from the west coast mostly, and have spent a fair bit of time with MacGillivrays Warblers. This
    bird looked identical, but with a complete eye ring.


    Dark Gray on head, facing to ligher under the throat.

    Feet & Bill

    Normal insect-eating warbler shaped bill…tweezer like and small

    Upper Back

    Dark gray fading to olive green

    Lower Back & Rump

    Olive green


    Olive green

    Breast, Belly, Flanks, Under Tail Coverts

    Bright yellow



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

    The complete eye ring made it not a Mourning Warbler, and range eliminated MacGillivray’s Warbler.
    Underside was much too bright from throat to undertail to be a female yellowthroat. The grayish hood
    was complete from upper back to lower breast, eliminating Hooded Warbler. It was larger than a
    Wilson’s warbler. The throat was definitely gray, eliminating the possibility of female or young male
    Nashville Warbler. Bill too thin to be any sort of vireo. No streaks on breast eliminated Canada warbler
