The Izu thrush, which is observed solitary or in small flocks of two or three birds (3), breeds primarily between March and June, when it lays between two and five eggs (2). The nest, situated on a low branch or occasionally on the ground, is made of grass and leaves, stuck together with mud and covered with moss (2). The Izu thrush forages in the forest canopy, on the ground, in leaf litter, and in more open areas adjacent to woodland. It feeds on fruits, seeds and invertebrates, particularly caterpillars, and brings earthworms, insects and centipedes to the nestlings (2).
