Field Marks and
A clear phalarope at first glance. Upon closer examination, it became evident
that this was a red phalarope in nonbreeding plumage and not a more common
red-NECKED phalarope. Here are the main points that make this bird a red
Quite bulky in appearance (compared to red-necked).
Pale gray (unstreaked) back with dark primaries, white tail and flanks. Overall white neck and face with dark gray edges of crown. The top of its crown and forehead were white. A black face patch flared out (widened) behind its eye.
Upon close examination, a slight hint of red was still visible on its neck even though it otherwise appeared fully transitioned into nonbreeding plumage.
Straight, dark, straw-like bill with reddish base of lower mandible.
|Song or call & method of delivery:||Silent|
|Behavior:||Swimming/foraging in open water. Typical "herky jerky" style of phalarope foraging behavior.|
|Habitat:||Open water on Lake Powell, far from the shore. It was probably on one of the widest sections of Warm Creek Bay.|

Red-necked phalarope: Similar nonbreeding plumage
to red phalarope. However there are several distinct differences that make the
reported individual a red phalarope.
The bird observed had a stockier appearance than what I'd expect from red-necked phalarope. Red-necked phalarope would also have a thin, all dark, "needle-like" bill. The base of the lower mandible on a red-necked would not show a slight reddish color as it does in nonbreeding red phalarope (this is visible in my photos). In addition, red-necked phalarope would show more streaking on its back, and the dark face patch on a red-necked would taper downward behind its eye, instead of flaring out like it does on the reported bird.

We got great looks at this bird from a rental boat. It was quite tame and
allowed us to approach for photos without seeming to be disturbed. We found
the red phalarope while heading towards the state first blue-footed booby on
Warm Creek Bay. Amazingly, we saw this bird again while leaving Warm Creek
Bay over an hour later. Credit goes to others on board who spotted the red
phalarope before I did.
Although this bird was found quite close to the Arizona border, GPS coordinates (given above) show that this bird was observed in Utah.
