A conservation group has tracked a migration for the ages, in which a male bar-tailed godwit flew from Alaska to New Zealand without taking a single break.
As the Guardian reports, the bar-tailed godwit departed southwestern Alaska on September 16 and arrived 11 days later at a bay near Auckland, New Zealand. The bird, designated 4BBRW (for the blue, blue, red, and white identification rings attached to its legs), was tracked by Global Flyway Network, a conservation group that studies long-distance migrating shorebirds.
Bar-tailed godwits (Limosa lapponica) are exceptional birds, featuring some mind-bogglingly long migratory routes. The wading birds spend their summers in the arctic regions of the Northern Hemisphere (where they breed) and then fly south for the winter, in some cases as far as Australia and New Zealand. Bar-tailed godwits are fast and lightweight, with
Marine biologists are astonished after a Cuvier’s beaked whale held its breath for nearly four hours during a deep dive. The unexpected observation shows there’s much to learn about these medium-sized whales.
Scientists from Duke University and the Cascadia Research Collective recorded the unbelievable dive during field observations off the coast of Cape Hatteras, North Carolina, in 2017. In the first of two epic dives, the Cuvier beaked whale, wearing tag ZcTag066, stayed underwater for nearly three hours. A week later, the whale outdid itself, holding its breath for a bewildering three hours and 42 minutes.
“We didn’t believe it at first, because these are mammals after all, and any mammal spending that long underwater just seemed incredible,” Nicola Quick, the lead author of the new study and a biologist at Duke University, said
