Not sure how anyone knows it didn`t land anywhere on the way, amazing even if it did.

At 37 KM per hour it is not a trawler

I'm also amazed at Hummingbirds flying the 500 +/- miles across the Gulf of Mexico...where do they store the energy to do that?

...teeny-tiny GPS transceiver. (honest)


In a recent paper, a group of researchers said the arduous journeys challenge “underlying assumptions of bird physiology, orientation, and behavior,” and listed 11 questions posed by such migrations. Dr. Piersma called the pursuit of answers to these questions “the new ornithology.”
The extraordinary nature of what bar-tailed and other migrating birds accomplish has been revealed in the last 15 years or so with improvements to tracking technology, which has given researchers the ability to follow individual birds in real time and in a detailed way along the full length of their journey.
“You know where a bird is almost to the meter, you know how high it is, you know what it’s doing, you know its wing-beat frequency,” Dr. Piersma said. “It’s opened a whole new world.”

Don`t they need to stop to rehydrate? Or eat? Think of the energy and moisture expended. Seems not but...
We can fly Vancouver><Sydney direct, only a bird can from Alaska. More strength to their tiny wings. But I could do without the visiting screeching Indonesian koels and cuckoos.

A lyre bird at Sydney`s harbourside Taronga Zoo has been recorded imitating an evacuation siren and telling people to "evacuate now". It seems to be connected to the recent evacuation when 5 lions escaped their enclosure!
