About These Birds
Common Raven
The common raven is among the most intelligent birds, demonstrating tool use, future planning, and social manipulation in scientific studies. In many cultures, ravens feature prominently in mythology as creators, tricksters, or messengers. Their complex vocalizations include over 30 distinct calls.
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.
