About These Birds
American Robin
The American robin is widely regarded as a harbinger of spring across North America. Despite its name, it is a true thrush unrelated to the European robin. American robins produce two to three broods per year and are among the earliest birds to sing in the morning chorus.
Bismarck Island Thrush
The Bismarck Island Thrush is a thrush endemic to the Bismarck Archipelago, particularly New Britain and Bougainville. It has warm brown plumage typical of island thrushes in the Turdus genus. It forages on the forest floor and in trees for earthworms, fruits, berries, and invertebrates.
