Field Marks and Identifying Characteristics: |
A Pluvialis plover in no-breeding plumage, with a thin bill and strong
supercillium, and a very rich golden-rufus-brown color and a pale belly. We
watched it for quite awhile through the scopes, and compared it to drawings and
photos in our 'Sibley' and 'Shorebirds of North America: The Photographic Guide'
and concluded unanimously that Pacific Golden Plover was the best match. We
looked closely at the tail/wing length ratio, and the wing tips just barely were
longer than the tail (see photos and video) |
Song or call & method of delivery: | None heard |
Behavior: | Foraging in shallow brackish water. Standing still,running a short distance,then plucking at presumed insects on the ground. |
Habitat: | In the Great Salt Lake, in shallow brackish water near mudflats. It was south of the causeway,so not in the pure salt water of the lake,but in the Farmington Bay section with salt water diluted by fresh water |
Similar
species and
how were they eliminated: |
Upon seeing the bird,I said "There's a plover,lets scope it, but its probably just a Killdeer". When we scoped it,it obviously was a Pluvialis plover in non-breeding plumage. We looked at it for awhile,and Pat thought it looked like a Golden Plover. I said "my instinct says Golden Plover,but my mind says its probably just a Black-bellied",so we pulled out both books and read the descriptions and looked at the drawing and photographs,comparing them with the bird in the scopes. The bird had a long thin bill,a strong supercillium,and was not gray,ruling out Black Bellied,so upon arriving at a Golden Plover,we looked at the books and saw the differences in color and the tail wing length ratio. There was nothing dull or gray about this bird,it was very richly colored golden rufus brown,and I though wing tips were about as long as the tail. Ned said they were slightly longer, but not by very much. Ned also though the pale belly on the bird also was a better match for Pacific. After consulting the books and looking at the bird for several minutes,we all came to agreement that the bird was a Pacific Golden Plover. Lifer for me,Mike and Pat. |
Previous
experience with this & similar species: |
None with Pacific Golden Plover. I saw 2 American Golden Plovers this spring on the AIC and hundreds of Black-bellied Plovers over the years. Ned had seen them before,although I don't know the details of his sighting. |

Additional_Comments: | I will send low quality photos and video to the webmaster. Although they don't conclusively show the wing/tail length ratio,they do show its a Golden Plover(no black on the base of the wing when it raises its wings in the video),and very richly colored.So they are supportive of what we saw,but not conclusive in them selves. |
