Bird Flies from Australia to Aleuts in Eight Days

From Birdlife International comes this map and amazing story of transmitters fitted to four Ruddy Turnstones, one of whom flew from the Aleutian Islands to Austalia in just eight days of flying, and three of whom flew from Australia to Taiwan in just six days of flying:

Four birds fitted with ultra-light geolocators took just six days to fly from Australia to Taiwan before continuing on to northern Siberia. One bird then completed its return trip back to Australia via the Central Pacific - a total round-trip of 27,000 km!

.... The researchers therefore decided to use new 1 gram light-sensor geolocators - supplied by British Antarctic Survey in Cambridge, England - and fitted them to eight Ruddy Turnstone spending their non-breeding season in south-east Australia in April 2009. Four geolocators were eventually retrieved from birds between 20 October 2009 and 8 January 2010.

"All four birds flew 7,600 km non-stop to Taiwan in just over six days, with three apparently travelling together", said Dr Clive Minton. They then flew on to northern Siberia, following separate paths and stopping over at different sites. "By early August, two had moved to Korea and south-eastern Siberia, respectively, but another bird returned to Australia via the Central Pacific!"

The Pacific bird spent 26 July -15 October on the Aleutian Islands before flying 6,200 km across the Pacific in four days to Kiribati, and then it made another four-day, 5,000-km flight to eastern Australia. "Five days later it was back in south-east Australia having completed a 27,000-km round trip", added Ken Gosbell - Chairman of the Australasian Wader Studies Group.
