Field Marks and Identifying Characteristics: |
While conducting our survey route on the Intermountain West Shorebird
Survey of Great Salt Lake, I was counting Red-necked and Wilson's
Phalarope from the bridge on the north side, when I spotted an odd
Phalarope that looked different from the thousands of Phalarope I had
seen that day. It had a smooth pale gray back and a unique pink color on
the neck that stood out, The pink was mostly on the neck but also in
messy patches on the breast, flanks and rump. I also noted the basal
1/8th of the bill was yellow on both the upper and lower mandible and
the legs were yellowish. It was intermediate in size between a
Red-necked and Wilson's Phalarope, notably bigger than the Red-necked
and almost as big as a Wilson's. Compared to both it was chunkier and
shorter necked. Best match was a molting adult Red. After I got home and
searched the Macaulay Library, I found several examples of a Red in a
similar stage of molt, such as

Similar
species and
how were they eliminated: |
Direct comparison with both Red-necked and Wilson's Phalarope. Red-necked: Smaller and slimmer with longer neck and longer, thinner all black bills, more streaking on back and dark legs. Most were in basic or juvenile plumage, but a few were molting or in mostly alternate plumage, but none had the messy pink pattern seen on this bird Wilson's: Larger and slimmer with much longer neck in proportion and long thin black bill, longer legs and a weaker line behind the eye. Most were in basic or juvenile plumage, a few males still in partial alternate plumage, but none had the messy pink pattern seen on this bird |
Previous
experience with this & similar species: |
Yes, many both in Utah and on the ocean. Many hundreds of thousands of Red-necked and Wilson's Phalarope |
