Description of Habitat

Mud flat in small cove of Dead Creek

Behaviors Observed

Peacefully foraged on mud flats with small flock of roughly 40 Semipalmated and Least Sandpipers. Relocated a few times closer to oberserver until a Northern Harrier strafed the group, chasing off roughly 25 of the birds including this one.

Description of Vocalizations

None heard that could be exclusively attributed to this individual

Verbal Narrative & Description of Observation

Observed this bird feeding with a flock of roughly 40 Semipalmated and Least Sandpipers. This bird relocated with short flights several times, moving closer to the observer. A young Northern Harrier subsequently flew low at the flock, scaring them all into flight. Though some of the flock returned, the majority, including this bird, headed south.

Relative Size & Shape

Small "peep" sized and shaped shorebird, slightly larger than adjacent Semipalmated Sandpipers and appearing slightly taller

Head

Relatively light face, darker gray crown, dark eyes, white throat, nape not noted

Feet & Bill

Black legs, appearing slightly longer than adjacent Semipalmateds', toes not noted; long black, slightly drooping bill was also more pointed than Semipalmateds' bills

Upper Back

Dark with some reddish

Lower Back & Rump

not noted

Wings

Generally gray and dark; primary extension reaching about same as tail

Breast, Belly, Flanks, Under Tail Coverts

Belly, flanks, undertail coverts and front of breast white (distinguishing from dull breasts of juvenile Semipalmateds)

Tail

not noted

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

Distinguished from adjacent Semipalmated Sandpipers by slightly larger size; longer, more drooped and pointed bill; red (and black) upper scapulars cleanly distinguished from surrounding gray by white "line" below them; reddish on upper back; clean white front of breast; relatively lighter face; overall more gray than grayish brown bird. Distinguished from White-rumped Sandpiper by size only slightly larger than Semipalmateds; primary and tail extension similar; clean white breast; generally more pudgy shape rather than streamlined. Distinguished from Red-necked Stint by longer bill, white front of breast, and size slightly larger than Semipalmateds. Plumage as described distinguished as juvenile.

Other Notes & Comments

Unreasonably poor quality photos attached, taken with phone "camera" through scope before a Northern Harrier chased off most of the shorebirds including this one (and before opportunity to wield an actual camera). Although atrocious quality, a few important features of reality are reflected in these photos of the Western on the right and a Semipalmated Sandpiper on the left. First the bill can be seen to be relatively long, drooping, and pointed. Second the bird appears slightly larger and longer legged than the Semipalmated. Also the red (and black) upper scapulars can be seen as a dark strip with a white border below them and clearly distinguished from gray feathers below. Also the clean white front of the breast is somewhat apparent.
