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.
Black-billed Thrush
The Black-billed Thrush is a medium-sized, plain thrush widely distributed across northern and central South America from Colombia and Venezuela south to Bolivia and Brazil. It has olive-brown upperparts, streaked brownish-white underparts, and a distinctive dark bill. It inhabits forest edges, secondary growth, gardens, and open woodland, feeding on earthworms, insects, and berries.
