...celeration." Patek acknowledged that falcons can dive as fast as 300 miles per hour, but that the raptors must start from very high altitudes and get a boost from the force of gravity to reach those speeds. In comparison, animals such as trap-jaw ants and mantis shrimp (which formerly held the record fo...

Study documents marathon migrations of sooty shearwaters

The new study shows that, contrary to previous assumptions, sooty shearwaters do not make a big pan-Pacific sweep to cover all of their feeding areas in the Northern Hemisphere. Instead, individual birds went to...
