|Date:||May 28, 2001|
|Length of time observed:||1 hr|
|Location:||Ouray NWR, auto tour stop #3|
|Distance to bird:||25 to 30 ft|
|Light Conditions:||Variable but fairly bright with sunlight filtering through the high clouds.|
|Detailed description of bird:||
Plumage varied slightly from bird to bird, however all birds displayed the
Dark gray to black bill with slight droop at tip
Wingtips extending beyond the tail tip
Totally white rump without a median stripe
White breast with dark streaking
Darkly streaked flanks
Wings dark overall with buffy edges to feathers
Light (whitish) supercilium
All but one bird had the following features in addition to those listed
One bird was more buffy overall (lacking the rusty coloring) and had less extensive streaking on the flanks and breast.
|Song or call & method of delivery:||Not heard|
We observed the birds feeding in shallow water, on mudflats and among low
grasses and plants dotting the mudflats.
Also, we saw a couple of the birds preening. We watched the birds fly on two short "alarm" flights. They flew as a group and returned to the original area within 15 to 20 seconds.
|Habitat:||A small shallow pond with sparsely vegetated mud flat surrounding it. More dense vegetation surrounded the immediate mudflat area. The vegetation consisted of low grasses and low small shrubby plants.|
how were they eliminated:
|Baird's Sandpiper--Eliminated because it doesn't have dark streaking on it's flanks, and also because it has a white rump with a dark median stripe.|
|Previous experience with this & similar species:||
White-rumped: We identified one bird in Ontario, Canada in May 1993.
Baird's: We regularly see and identify birds migrating through Utah.
