Overview

Corn Crake: Medium rail, buff-yellow overall with brown-barred flanks, conspicuous chestnut wing patch, gray head and neck with dark crown, yellow bill. Eats worms, insects, snails, slugs, sometimes seeds and grains. Weak flight with legs dangling, drops back into vegetation after a short distance.

Range and Habitat

Corn Crake: Very rare fall visitor to the east coast, but sightings have dropped significantly as European populations have declined.

Breeding and Nesting

Corn Crake: Nest is a shallow cup built among dense grasses or vegetation in meadows. Lays eight to twelve pale green eggs with red brown spots. Eggs and chicks tended only by female, while male may mate with additional females. Incubation 16 to 19 days. Chicks begin flying when 34 to 38 days old.

Foraging and Feeding

Corn Crake: Very active feeder but normally stays within dense grasses and meadow vegetation as it hunts for a wide variety of insects, invertebrates, clams, and small vertebrates. Also consumes some foliage and seeds.

Vocalization

Corn Crake: Monotonous rasping "crex-crex."

Similar Species

Corn Crake: Sora juvenile is slightly smaller, lacks chestnut wing patch, chestnut-brown back lacks distinctive mottling, and white undertail coverts lack barring.
