Almost half the breeding population of the world’s most endangered penguin species, the yellow-eyed penguin, has disappeared in one part of New Zealand and conservation groups believe commercial fishing is to blame.
The yellow-eyed penguin is endemic to New Zealand’s South Island and sub-Antarctic islands, where there are just 1,600 to 1,800 left in the wild, down from nearly 7,000 in 2000.
During a recent survey of the island sanctuary of Whenua Hou (Codfish Island), department of conservation staff made the alarming discovery that close to half the island’s breeding population of penguins had vanished. Elsewhere in New Zealand the bird’s population is at its lowest level in 27 years.
Forest & Bird’s chief executive Kevin Hague said because the island was predator-free the evidence pointed to the animals being caught and drowned in the nets of commercial fishing trawlers. Only 3% of commercial trawlers have independent observers on them to report bycatch deaths.
“Unlike previous years where disease and high temperatures caused deaths on land, this year birds have disappeared at sea,” said Hague.
