A short video takes viewers behind the scenes to see how Dutch biologists capture, measure and tag Arctic terns in Svalbard to study their amazing annual roundtrip between Antarctica and the Arctic, during which they log over 80,000 kilometers, the world’s longest bird migration. For more details, see earlier post, Return of the terns.
