Penguin breeding season gets underway

tawakiSpring is springing all around us and penguins up and down the coast are likely to be incubating eggs. 

Trust Ranger, Reuben Lane, was out last month to check on the blue penguin (korora) nest sites we monitor in the Buller area but our focus has been on the start of our second season of monitoring Fiordland crested penguins (tawaki) in South Westland.

Reuben said: “A scenic flight over the Cascade moraines and New Zealand’s last great swamp should be at the top of everyone’s bucket list! Thanks also to the Long family for their warm hospitality and invaluable work with the video monitoring study of the tawaki living around their house at Gorge River.”

The first year’s monitoring showed the presence of possums, stoats and rats and that the penguins generally disregarded them.  However there was one record of a juvenile penguin being killed by a stoat and the second year of monitoring will provide further clues as to threats to the tawaki populations. 

 

The purpose of the study is to establish which, if any, predators do pose a threat to the penguins so as to inform any future predator control.
