When to expect brown creepers in Wyoming

Brown Creepers live in Wyoming all year. Cold, very windy winters. That makes the cold months the time your yard matters most to them: their winter diet shifts toward overwintering insects; some suet.

Semi-arid high plains and basins with major mountain ranges; most towns lie above 5,000 ft.

Nesting in Wyoming

Across Wyoming, brown creepers typically nest from June. Nest site: hammock nest behind loose bark on dead trees. Females lay 5–6 eggs, incubate for 13–17 days, and young leave the nest after 13–16 days.

Short, warm summers with cool nights.

Brown Creepers don't use nest boxes. Keep dense native shrubs and trees such as bur oak, chokecherry, common hackberry for nest sites.
Delay heavy pruning of shrubs until after June.
