Other observers include Pam Allen, Reid Allen, and many unidentified other observers. | Elimination of similar species: There are very few shorebirds that are this pale. Compared directly to a Sanderling, this bird had a longer neck, a dark cap, a black spot around the eye, and darker upperwings which were particularly visible in flight. Red-necked Phalarope (which would be even more unusual at this date) was eliminated by bill size and shape and unstreaked mantle. | The original documentation form event lasted from 09:35:00/10:15:00.
