    Bright sun and fresh snow which made phone-scoping difficult. Most of the observation was in great lighting, with the sun over my shoulder. I took dozens of photos, but the were all either blurry or the head was not visible.

    Minox 8x42 binoculars, Swavorski 25x - 50x scope

    Observer’s Previous Acquaintance With This or Similar Species

    I have seen many WCSP, in both Vermont and California, though never positively identified a Gambel's anywhere

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

    Overgrown weedy field that has been great for sparrows since fall. Heavy snow pushed many birds to the roadside, at least 5 WCSP present during this observation

    Behaviors Observed

    Feeding along the road with other sparrows. The photos were taken when it was in a driveway, after being flushed by a truck. Its spent considerable time in a large maple, which seemed strange for WCSP, before dropping down to a bare patch of dirt

    Description of Vocalizations

    Not heard, probably silent?

    Verbal Narrative & Description of Observation

    It unclear exactly how many individuals this observation refers to, as there were several WCSP in the vicinity, and the two most conclusive views came >30mins and 200 meters apart. At one point, two immature WCSP were right next to each other, which provided a great comparison, and the differences were quite noticeable. The longest views, and photos, came when the bird was alone.

    Relative Size & Shape

    Similar to other WCSP

    Head

    Generally similar to other immature WCSP, with two brown crown stripes on a paler head. The big differences were the pale lores, less distinct eye stripe behind the eye, and larger gray nape

    Feet & Bill

    Bill was a bight shade of orange, noticeable different from the orangey/pink bill of other WCSPs

    Upper Back

    Similar to other WCSPs

    Lower Back & Rump

    Similar to other WCSPs

    Wings

    Similar to other WCSPs

    Breast, Belly, Flanks, Under Tail Coverts

    Similar to other WCSPs

    Tail

    Similar to other WCSPs, though I repeatedly noticed a flicking of the tail that I had not seen in others. Almost a robin like, lateral flick as it fed

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

    Eastern White-crowned Sparrow (Z. l. leucophrys) eliminated in direct comparison by the pale lores and orange bill

    Other Notes & Comments

    Immature.

    Note added March 22: It appears this bird was unknowingly re-found two days later, and properly photographed! Now I can sleep at night knowing that it wasn’t just wishful thinking...
    http://ebird.org/ebird/view/checklist/S35330810, I suggested to Ian that he have the observer submit another RSD, but in case she doesn’t, it would be great if this checklist and photo could be filed with mine.
