Field Marks and Identifying Characteristics: |
Pale gray phalarope, foraging near Northern Shovelers and the three continuing
Harlequin Ducks where the relatively fresh water flows under this bridge to meet
the saltier water of the north side of the causeway. Pale gray above without
stripes or other noticeable patterning. (One feather of the right wing, a
tertial I think, maybe a greater covert, can be seen in the photographs to be
darker than the others, but with pale fringing. I'm not sure whether this is
retained from juvenile or breeding plumage.) White beneath, including flanks,
front of neck, and most of head. Dark gray back of neck to rear of crown, where
dark gray split around a white central patch on the top of the head. Black
around eye and immediately behind it. Relatively thick bill for a phalarope,
black, with a blunt tip and a orange base on the lower mandible, with a little
bit of orange also at the base of the upper mandible. Black-looking folded
primaries. (see photos) |
Song or call & method of delivery: | None observed. |
Behavior: | Picking at small prey in the surface of the water. Spinning back and forth, but not making the complete circles phalaropes sometimes make. |
Habitat: | Surface of the Great Salt Lake. |
Similar
species and
how were they eliminated: |
The other two species of phalaropes are the only floating shorebirds that could be confused with this Red Phalarope. Wilson's Phalarope eliminated by the black mark around and behind the eye, and the relatively thick black bill of this bird with an orange base of the bill. Red-necked Phalarope eliminated by the solid pale gray mantle of this bird (not striped as in Red-necked Phalarope) and also by the relatively thick bill with pale base. |
Previous
experience with this & similar species: |
I have seen Red Phalaropes on only one other occasion: many of them on one fall pelagic birding trip off San Diego. I have much experience with Wilson's and Red-necked Phalaropes. |

Other observers who independently identified this bird: | Seen on a Bridgerland Audubon Society field trip, with Craig Fosdick, Andrew Durso, Allen Stokes, and three other birders whose names I have forgotten. We later met Bob Huntington on the causeway and he was able to relocate and independently identify the bird as well. |
