CANBERRA, Australia (AP) — A younger bar-tailed godwit seems to have set a continuous distance report for migratory birds by flying at the least 13,560 kilometers (8,435 miles) from Alaska to the Australian state of Tasmania, a chook skilled stated Friday.
The chook was tagged as a hatchling in Alaska throughout the Northern Hemisphere summer time with a monitoring GPS chip and tiny photo voltaic panel that enabled a global analysis crew to comply with its first annual migration throughout the Pacific Ocean, Birdlife Tasmania convenor Eric Woehler stated. As a result of the chook was so younger, its gender wasn’t identified.
Aged about 5 months, it left southwest Alaska on the Yuko-Kuskokwim Delta on Oct. 13 and touched down 11 days later at Ansons Bay on the island of Tasmania’s northeastern tip on Oct. 24, in keeping with knowledge from Germany’s Max Plank Institute for Ornithology. The analysis has but to be revealed or peer reviewed.
The chook began on a southwestern course towards Japan then turned southeast over Alaska’s Aleutian Islands, a map revealed by New Zealand’s Pukoro Miranda Shorebird Heart exhibits.
The chook was once more monitoring southwest when it flew over or close to Kiribati and New Caledonia, then previous the Australian mainland earlier than turning instantly west for Tasmania, Australia’s most southerly state. The satellite tv for pc path confirmed it lined 13,560 kilometers (8,435 miles) with out stopping.
“Whether or not that is an accident, whether or not this chook bought misplaced or whether or not that is a part of a standard sample of migration for the species, we nonetheless don’t know,” stated Woehler, who’s a part of the analysis mission.
Guinness World Data lists the longest recorded migration by a chook with out stopping for meals or relaxation as 12,200 km (7,580 miles) by a satellite-tagged male bar-tailed godwit flying from Alaska to New Zealand.
That flight was recorded in 2020 as a part of the identical decade-old analysis mission, which additionally entails China’s Fudan College, New Zealand’s Massey College and the World Flyway Community.
The identical chook broke its personal report with a 13,000-kilometer (8,100-mile) flight on its subsequent migration final yr, researchers say. However Guinness has but to acknowledge that feat.
Woehler stated researchers didn’t know whether or not the newest chook, identified by its satellite tv for pc tag 234684, flew alone or as a part of a flock.
“There are so few birds which have been tagged, we don’t understand how consultant or in any other case this occasion is,” Woehler stated.
“It could be that half the birds that do the migration from Alaska come to Tasmania instantly fairly than by means of New Zealand or it may be 1%, or it may be that that is the primary it’s ever occurred,” he added.
Grownup birds depart Alaska sooner than juveniles, so the tagged chook was unlikely to have adopted extra skilled vacationers south, Woehler stated.
Woehler hopes to see the chook as soon as moist climate clears within the distant nook of Tasmania, the place it should fatten up having misplaced half its physique weight on its journey.
