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
NASA has released satellite images showing an unstable mountain slope in Alaska experts warn could trigger a devastating “mega-tsunami.”
The mountain slope is located above a fiord called Barry Arm on Alaska’s south coast, which lies around 60 miles east of Anchorage.
The slope is partially supported by the Barry Glacier, but this body of ice has retreated significantly over the past decade. As a result, the slope is becoming more unstable, a team of 14 scientists said in an open letter published in May this year on the website of the Alaska Department of Natural Resources, Division of Geological and Geophysical Survey.
The retreat of the glacier is creating the perfect conditions for the slope—which is moving slowly downhill—to collapse suddenly, causing a rapidly-moving landslide with the potential to produce a massive tsunami wave reaching hundreds of feet in elevation along the shores of Barry Arm and the adjacent
