Graham Readfearn in The Guardian:
A juvenile bar-tailed godwit – known only by its satellite tag number 234684 – has flown 13,560 kilometres from Alaska to the Australian state of Tasmania without stopping, appearing to set a new world record for marathon bird flights.
The five-month-old bird set off from Alaska on 13 October and satellite data appeared to show it did not stop during its marathon flight which took 11 days and one hour.
Tagged in Alaska, the bar-tailed godwit, Limosa lapponica, flew at least 13,560km (8,435 miles) before touching down at Ansons Bay in north-east Tasmania.
The previous record was held by an adult male of the same species – 4BBRW – that flew 13,000km (8,100 miles) last year, beating his own previous record of 12,000km the year before.
