SYDNEY: A tiny songbird, the 0.42 oz (12 gram) Blackpoll Warbler flies from 1,410 to 1,720 miles (2270 to 2770 km) over the sea non-stop every year in incredible migration feat scientists describe as “on the brink of impossibility”.
The Blackpoll Warbler, which is smaller than a sparrow and only slightly larger than the British wren (Eurasian wren), was part of an extensive study that monitored the tiny songbird from northeastern North America all the way down to the northeastern coast of South America.
First author Bill DeLuca, an environmental conservation research fellow at the University of Massachusetts Amherst, and colleagues published their findings in the academic journal Biology Letters.
