Tiny songbird can fly the Atlantic, scientists confirm
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) Más...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?
What flight level? Bonus link: http://en.wikipedia.org/wiki/List_of_birds_by_flight_heights
Does it have to connect thru Atlanta?
Hummingbirds do the same thing, flying from the US to South America.
Most bird sources don't mention the weight or list it in grams. . . . . . .
