The Ornithological Society of New Zealand (OSNZ), also known as Birds New Zealand and BirdsNZ, is a non-profit organisation dedicated to the study of birds and their habitats in the New Zealand region. Founded in 1940, it caters to a wide variety of people interested in the birds of the region, from professional ornithologists to casual birdwatchers. The Society publishes a quarterly peer-reviewed scientific journal, Notornis, and a quarterly news magazine, Birds New Zealand (formerly Southern Bird). It also organises membership-based scientific projects, such as the Atlas of Bird Distribution in New Zealand. Source: Wikipedia (en)
