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.
Wilson's Bird-of-paradise
Wilson's bird-of-paradise is one of the most extraordinarily colored birds on Earth. Males meticulously clear a patch of forest floor as a display court, removing every leaf and twig. The species was virtually unknown to science until the late 20th century due to its restricted island range.
