The male sings when storms approach and again when storms have passed. [45] In addition to its song, the species has a number of calls used for communicating specific information, such as when a ground predator approaches and when a nest or another American robin is being directly threatened.
In bi-parental care, the male provides food and the female is a caretaker. Both ensure the survival of the offspring. The female may care for her young by covering them to keep them warm, shielding them from the sun or from rain and guarding them from predation. The male may also feed the female, who in turn regurgitates the food to the chicks.

The wood thrush is an omnivore, and feeds preferentially on soil invertebrates and larvae, but will also eat fruits. In the summer, it feeds on insects continuously in order to meet daily metabolic needs.
The female-biased sexual size dimorphism observed in many taxa evolved despite intense male-male competition for mates. [28] In Osmia rufa , for example, the female is larger/broader than males, with males being 8–10 mm in size and females being 10–12 mm in size. [ 29 ]
