When to expect mockingbirds in New Jersey

Northern Mockingbirds live in New Jersey all year. Moderate winters; Cape May and the shore hold many half-hardy birds. That makes the cold months the time your yard matters most to them: their winter diet shifts toward holly, hackberry, pokeweed and multiflora fruit.

Humid continental to subtropical, from the Highlands in the north to the Pine Barrens and Cape May.

Nesting in New Jersey

Across New Jersey, mockingbirds typically nest from March–August. Nest site: twig cup in shrubs and small trees 3–10 ft up. Females lay 2–6 eggs, incubate for 12–13 days, and young leave the nest after 12–13 days.

  • Northern Mockingbirds don't use nest boxes. Keep dense native shrubs and trees such as flowering dogwood, eastern red cedar, serviceberry for nest sites.
