An Australian Aboriginal rock art may depict a giant bird that is thought to have become extinct some 40,000 years ago, thereby making it the oldest rock painting on the island continent. The red ochre drawing was first discovered two years ago, but archaeologists were only…

This streaming video is a clip from 60 Minutes where Bob Simon and Bruce Beehler, a scientist from Conservation International, head off into the New Guinea wilderness in search of the Black Sickle Bill Bird of Paradise, Epimachus fastuosus, and -- amazingly -- the cameramen capture video of this species's rarely seen courtship dance.

Sixty-two-mile-long Lake Toba, seen in the center of this satellite image,
was created by the largest explosive volcanic eruption of the past
100,000 years -- an eruption whose aftermath holds important clues for us
today about rapid climate change, Drew Shindell says.

This fascinating video shows how South Pacific islanders fish for Skipjack Tuna for commercial export using hook, line and pole. Skipjack Tuna are more able to withstand the pressures of commercial fishing than other tuna species because they reach sexual maturity in one year and then spawn many times per season afterwards. Of course, they are not as commercially desirable because they are the smallest tuna species, but if humans cause the extinction of all other tuna species…

This informative video discusses the conservation of one of my research birds, the Rimatara (Kuhl's) Lory, Vini kuhlii, known by the natives as the 'Ura. Not only is this bird's story interesting, but it also exemplifies the complications and challenges of conserving any endangered species. This is part three of a three-part series [8:46]

A brilliant green tree tree frog with giant black eyes, tentatively classified as a Nyctimystes species, is one of 56 new species of animals discovered during a 2008 expedition to the remote island of Papua New Guinea.

Satomi's pygmy seahorse, endemic to Indonesia, is one of the world's tiniest seahorses. Two adults would fit head-to-head across the face of a penny and their offspring are each about the size of a 12-point apostrophe.

At under half an inch tall (13 millimeters), Satomi's pygmy seahorse -- named after dive guide Satomi Onishi -- is a strong contender for the world's smallest seahorse. With their tails stretched out straight, two Satomi's…

This species' home range is smaller than Manhattan Island.

For many decades, the white-eyes (Family: Zosteropidae) were known as the "Great Speciators" in honor of their apparent ability to rapidly give rise to new species while other birds in the same areas showed little or no diversification. But…
