This video from Australia says about itself:
The Little Tern is one of the most endangered birds in NSW with only a couple of thousand left in the wild. Over the past decade the NSW National Parks and Wildlife Service has engineered an intensive recovery program aimed at reversing the decline in their number. It’s been a successful campaign and one involving a huge effort by the community.
