When to expect eastern screech-owls in Connecticut

Eastern Screech-Owls live in Connecticut all year. Snowy winters with regular nor'easters; feeders carry chickadees, titmice and juncos through January and February. That makes the cold months the time your yard matters most to them: their winter diet shifts toward mice and roosting birds.

Humid continental with maritime moderation along Long Island Sound.

Nesting in Connecticut

Across Connecticut, eastern screech-owls typically nest from March–May. Nest site: tree cavity or nest box with wood-chip base. Females lay 2–6 eggs, incubate for 26–34 days, and young leave the nest after about 28 days.
