There are 34 species of birds that have been recorded living in the wild on Nauru, a small atoll in the Pacific Ocean with an equatorial climate. One species is endemic to the island, two were introduced by humans, and one, the zebra finch, is now locally extinct on Nauru. Out of the 25 species of birds that have been confirmed to occur natively on Nauru, 18 are non-breeding visitors. Only two land birds, the Micronesian imperial pigeon (example pictured) and the Nauru reed warbler, breed on Nauru. The island's environment has been described as one of the world's most modified due to surface mining for phosphate, bombing during World War II, and rapid urbanisation. Habitat destruction has most likely caused a decline in the numbers of some species, such as the Micronesian imperial pigeon and the black noddy. (Full list...)
