Tipping the scale at a mere 4.2 ounces (12 grammes), the white-throated, black-capped blackpoll warbler (Setophaga striata) migrates each autumn from New England to South America. The geolocators, weighing only 0.02 ounces, found that the birds completed an astonishing non-stop flight of between 1,410-1,721 miles. (www.telegraph.co.uk) 更多...
Coconuts do float, and can migrate to other islands via currents. However, if coconuts float in saltwater for a period of time they become sterile - they cannot make new coconut trees. And you thought this website was only for aviation news you can use... ;-)
Last I checked New England is somewhere in North America quite some distance from Europe and South America is also quite far from Africa! Maybe you should buy an atlas or else use Google Maps now that you are on a computer with Internet access.
This is "only" across the gulf, but still more impressive to me. Lots of small birds cross the gulf. They're so exhausted by the time they reach land that people can stand on shore with their arms out, and the birds will land on them. Very cool.
The stories got the weight wrong. Too many are alike and someone decided to convert the 12 grams, but the decimal point was wrong. The little bird runs aroudn a half ounce and 12 grams is close, but 12 grams is actually .42 not 4.2 ounces......
wow, such a light "aircraft" could easily be blown off course if it encounters a cross. Maybe it only initiates the trip when it has a direct tail wind?
Big misunderstanding on the weight of the warbler in the article. All of the news releases read the same with some minor changes. The weight is .12 to .15 grams or .42... ounces, not 4.2 ounces. Most bird sources don't mention the weight or list it in grams. . . . . . .
