Tracking tagged sooty shearwaters by satellite, scientists mapped the small bird’s 70,000 km search for food in a giant figure eight over the Pacific Ocean, from New Zealand via Polynesia to feeding grounds in Japan, Alaska and California and then back! Making the longest-ever electronically-recorded migration in only 200 days, the bird averaged a surprising 350 km daily. In some cases, a breeding pair made the entire journey together.
