When to expect black-capped chickadees in Oregon
Black-capped Chickadees 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 cached seeds and insect eggs; suet and sunflower at feeders; poison-ivy and bayberry fruit.
Marine west-coast climate west of the Cascades; high desert to the east.
Nesting in Oregon
Across Oregon, black-capped chickadees typically nest from April–July. Nest site: excavates or reuses cavities in soft, rotting wood; readily uses nest boxes. Females lay 1–13 eggs (usually 6–8), incubate for 11–14 days, and young leave the nest after 12–16 days.
