About These Birds
Northern Gannet
The northern gannet is a spectacular plunge-diver, folding its two-meter wingspan into an arrow shape to hit the water at up to 100 km/h. Air sacs under the skin and a reinforced skull protect it from the impact. Bass Rock in Scotland hosts over 150,000 gannets, the largest single colony of any seabird in the world.
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.
