Field Marks and
This bird had long black legs. We noted about one-third of the complete leg
length above the joint and two-thirds below.
The bird seemed much "taller" than the surrounding birds--mostly Western Sandpipers, Snowy Plovers and a few Baird's Sandpipers.
The bill was long, black and curved downward. For comparison, the length of the bill was one-and-a-half to two times the width of the head from front to back.
Its head and face were pale gray. A bright white supercillium contrasted with the gray face. The cap above the white eyebrow appeared slightly darker than the rest of the head.
The bird's back (and folded wings) were a striking extremely pale gray and the underparts were white. There was no visible variation to the gray over white pattern except for a very slight gray wash (no streaking) on the upper breast.
The bird had a slender overall body shape and a longer body length than a Western Sandpiper. Assuming the length of a Western Sandpiper at 6" would make this bird approximately 8" in length.
We also noted a narrow white wing stripe on the top surface of the wing as the bird was preening.
|Song or call & method of delivery:||Not heard|
|Behavior:||The bird chased several smaller birds, preened for a few minutes and occasionally pecked at the wet mudflat. When the surrounding birds flew, it ran several steps and then joined the flock of smaller birds.|
|Habitat:||Wet mudflat on the shore of the Great Salt Lake, next to very shallow water.|

Stilt Sandpiper has yellow legs. Its bill is also straighter with a slight
Dunlin does not have a bright white supercillium. It is also not as slender in body shape and is browner and more darkly colored overall in basic plumage. It also has a long straight bill with a slight droop.
