The Sooty Shearwater is a gray colored bird, with a 16 inch long body, and a wingspan of around three and a half feet.
Jet Lag Anyone?
They found the birds flew from New Zealand, to Antarctica, to Chile, to Japan, to the Bering Sea, to California, and then finally back to New Zealand. They traveled up to 565 miles in an day!
The birds make an enormous figure eight shape over the Pacific, tapping into the dense ocean feeding grounds all over as they go. In 200 days, the shearwaters were found to have covered 40,000 miles. That’s the longest migration on record!
