Description of Habitat

This Purple Sandpaper was feeding and moving about in the organic materials edging the southern portion of Shelburne Bay, west of what's commonly called "The Rock". It was feeding, resting and moving up and down the shoreline, occasionally in the shallow water.

Behaviors Observed

It was picking at prey and turning over the organic matter at the edge of the water. I didn't see it fly. The bird was not affected by the ovservers, abd those present kept a tespectful disance, such that the bird was present and observed at this same location the next day.

Description of Vocalizations

I didn't hear any vocalizations.

Verbal Narrative & Description of Observation

When I arrived at Shelburne Bay and took the short walk to the "rock", there were already several birders on hand viewing this purple sandpaper. Taran C showed it to me in her scope. It was working through the thin line of vegetation at the edge of the water to the west of the big rock. It was well camouflaged when it was not moving. But it picked several timmes and began to work through the vegetation.

Relative Size & Shape

It was larger than the peeps, about the size of a Dunlin. The shape was stocky.

Head

The head was a uniform brownish gray color. There was white through the eye forming short and broken supercilium. There was a black mark in front of the eye.

Feet & Bill

The feet were a bright orange yellow. The bill was slightly drooping, thick at the base and taperes to a blunt tip. The bill coloration was yellow at the base and dark for the rest of the bill.

Upper Back

The upper back is very dark with some gray woven through.

Lower Back & Rump

Dark brown feathering with a r
gray border.

Wings

I didn't observe the bird in flight.

Breast, Belly, Flanks, Under Tail Coverts

Breast light gray and extensive white on belly.

Tail

Uppertail was uniformly dark. Did not observe the undertail.

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

This bird is superficial similar to a Dunlin, however the presence of the yellow legs and yellow at the base of the bill and very dark coloration on its back eliminated the species.

Other Notes & Comments

I am submitting this RSD at the request of Jacob Crawford. Apparently none has been submitted since the January sighting and, although I was not the original observer, Jacob asked if I would fill one out.
