The warmest month in the Arctic Circle still means temperatures below 50 degrees. But that doesn’t deter about 200 species of Arctic birds from making the northernmost part of the Earth their home for at least part of the year. We asked ornithologist Dr. Nathan Senner, who studies Arctic species with the Cornell Lab of Ornithology, for his top 10 list of interesting Arctic birds. His selections include birds with long migratory flight patterns, two with flamboyant mating rituals and another with a distinctive call that differs during day and night.
