A pair of white-winged black terns (Chlidonias leucopterus) nested at a South Canterbury lagoon during the New Zealand summer of 1973-74. One chick was hatched on the second attempt, but it apparently did not fledge. This is not only the first documented record of white-winged black terns nesting in New Zealand but also the first undoubted record for the entire Southern Hemisphere.
