When to expect brown creepers in Oregon

Brown Creepers live in Oregon all year. Mild, rainy winters in the Willamette Valley; cold, snowy winters east of the Cascades. That makes the cold months the time your yard matters most to them: their winter diet shifts toward overwintering insects; some suet.

Marine west-coast climate west of the Cascades; high desert to the east.

Nesting in Oregon

Across Oregon, brown creepers typically nest from May–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.

Dry summers west of the Cascades; hot days in the high desert.

  • Brown Creepers don't use nest boxes. Keep dense native shrubs and trees such as paper birch, chokecherry, ponderosa pine for nest sites.
  • Delay heavy pruning of shrubs until after June.
