Plants provide model for new shape-changing materials

...to make a dive towards the intended victim. As the raptor changes gear to fly southward at lightening speed, it must sense what the outside forces and pressures are for its trajectory. Similarly, for an aircraft wing, engineers would need a material that's mechanically flexible. But the designers also need...

...pecies, DeWoody said. "It's very likely that other raptor biologists will follow this with similar studies on other species of interest like bald eagles," he said. This project is one part of a larger research program on the eagles of Naurzumski Gosudarstvennyi Zapovednik (Naurzum State Nature Reserve), a l...

Ancient raptors likely feasted on early man, study suggests

... (12 kg). McGraw says that scientists think that a raptor about the same size as a modern-day African crowned eagle may have killed the young hominid.

Eavesdropping nuthatches distinguish danger threats in chickadee alarm calls

...ecies," said Templeton. "Nuthatches can tell if a raptor poses a high or low danger from the chickadees alarm call." His earlier work showed that the chickadees had two types of alarm calls to warn about predators. When they see flying raptors birds of prey such as hawks, owls and falcons they issue a ...
