I did see and hear some birdlife, though, including ravens, chickadees and the agile white-breasted nuthatch, Sitta carolinensis. This bird can often be seen upside down, creeping down the side of a tree or even hanging from the underside of a branch. They exhibit similar behavior to red-breasted nuthatches, but have different, lighter coloring.
The white-breasted nuthatch is a non-migratory year-round Wyoming resident. I have occasionally seen this species in town, as well at in the pine/aspen forest.
I don't know this bird well enough to form a definite opinion of his personality (I've only seen this species occasionally, and usually for a very short period of time), but I like the description by Winsor Marrett Tyler published in the 1948 Smithsonian Bulletin: "The white-breasted nuthatch is a droll, earnest little bird, rather sedate and
unemotional. He is no great musician and seems to lack a sense of humor. He has
none of the irrepressible fidgetiness of the house wren, none of the charming
happiness of the song sparrow; he appears to take life on a matter-of-fact
level. He is short-necked, broad-shouldered, sturdy, quick and sure in his
motions, suggesting an athlete, and as we study him on his daily round, as he
hops up and down over the bark, we see that he is an athlete with marked skill
as an acrobat, like the tumbling kind, as much at home upside down as right side
up."
Winsor Marrett Tyler, by the way, was a Massachusetts doctor with a great interest in birds. He also reportedly read Shakespeare for fun each winter -- my kind of guy.
