Sorry, that's the only one.

Northeastern Illinois, at a municipal reservoir known for migrating shorebirds 10 Sep 2021

Thanks @Benjamin and @blackburnian

There was no reddish at all on this bird. Outer tail feathers seem to be white.

Northeastern Illinois, 13 Sept 2020. Digiscoped, cellphone/spotting scope. No foliage anywhere near the bird to affect coloration.

Thanks!

Audio, recorded in Pima County, Arizona (De Anza Trail near Tubac). We could not locate the bird in dense shrubbery and trees. The bird pips about every 3 seconds. Audio recording 26 seconds in length, on Clyp.It: https://clyp.it/0ccelkxu?token=086dc0abe7d726932769e00e84c254af

Thanks much all! This has been a very informative discussion.

What are the implications of the lack of a white chin strap? Here's another image, with the exposure increased in post processing.

Is the markedly smaller of these geese a small Canada Goose or is it a Cackling Goose? I estimate the wingspan to be about 3/4 that of the larger geese in the flock. Northeastern Illinois, September 22, 2018. Bird on left: Bird on top: Bird in middle:

Thanks!

Seemed to be larger than the nearby Least Sandpiper. Today, northeastern Illinois. Didn't seem streaky enough to be a Pectoral Sandpiper.

Thanks! Dark eye, large bill?
