In addition to being efficient fliers, birds also appear to be good meteorologists to the enormous surprise of the meteorologists among the researchers. We therefore must conclude that the birds fly much more efficiently than what we calculate on the basis of known flight properties." We know this from research with satellite-tagged birds. "The truth is, they fly for an average of up to 9 days at a time. ![]() "When we start calculating from the energy content of the fat burned and the assumed air resistance of birds, it seems that a bar-tailed godwit can fly for a maximum of 4 days at a time," lead author of the paper, migratory bird researcher Theunis Piersma of NIOZ, Royal Netherlands Institute for Sea Research and University of Groningen says. ![]() Once it arrives in New Zealand, only 215 g of that remains.

Instead of divvying up cabin time, they rotated visits between four impeccable New England estates and a luxurious apartment the size of Rhode Island. ![]() ![]() It's just that the things they were fighting over were not who would get the good china, but who got the New York City Public Library. When storied philanthropist and New York Synonym for Rich Brooke Astor died at the incredible age of 105, her family, like any family, fought over her remains.
