Birds fly over 7000miles non-stop

by the Bar-tailed Godwits, flying 5-9 days without rest to cover over
7000 miles.

About 10 years ago Charlie Spratt, John Good and I visited a Laysan
albatross colony on Kauai (Hawaii) and learned of a research project that
was tracking the birds with gps telemetry. There was a website where you
could get the lat/longs of the subject birds and track them on your National
Geographic globe. During the nesting season when the birds were feeding
their young they would soar (dynamically) to about 100 miles off Seattle,
then down to about San Francisco and back to the nest, barf up a meal for
the chick and do it all over again.

Some of the birds made similar trips to the Aleutians.

On a recent visit to the Albatross Colony on the south island of New
Zealand, I discovered that researchers report juveniles fly from the
nest and only return for breeding, maybe a year or two later, in which
period they don't set foot on land. In the process, they
circumnavigate the globe several times. I watched and photographed
several birds dynamic soaring and they definitely use the zooming
technique that has been described here before.

Of course, albatrosses are pretty big. The migration of smaller birds
and butterflies is perhaps more astonishing.

But curious minds want to know if they alight on the water.

They do. The detail is in

Apparently they can make shallow dives under water, and, if they land
on water, they can become trapped there - becalmed.
