Sooty shearwater

Source: wikipedia
The sooty shearwater (Puffinus griseus)crosses the Pacific Ocean in less than a year and travels on average 65.000 kilometres. The bird flies from its nesting home in New Zealand to areas off the coasts of Alaska, Japan, and California, and back. During this migration the shearwater draws a large ‘8’ across the Pacific Ocean and profits from constant air currents (such as the trade wind). This way, shearwaters can travel more than 900 kilometres a day.
