The Tawaki Project

@tawaki-project.org

The Tawaki Project works towards unraveling the mysteries of the world's least known penguin species - New Zealand's crested penguins or tawaki.

Tawaki are notoriously hard to find, making it nearly impossible to know their exact population size. This also means we can't easily tell whether their numbers are stable, growing, or declining.

The 2025 tawaki moult period is coming to an end. In Patra/Doubtful Sound most penguins have finished their 'scruffy' phase and are sporting a new coat of feathers. In the next week or two they will all leave on their big autumn-winter journey to the subantarctic region.

Tawaki are showing up along the southeast coast of the South Island for their annual moult. They should be pretty difficult to spot - unless they come out of their hideyholes for a quick drink. In that case, it's important to give them room and leave them in peace.

Some of the penguin colonies on the Antipodes Islands are pretty inaccessible. This is particularly true for most of the sea cave colonies. To get an idea about the number of penguins we use small #fpvdrones to take a closer look. It becomes a virtual visit without the disturbance of a human.

Coming home to the Anchorage Bay colonies can be challenging for Erect-crested penguins even on relatively calm days. Slithering through kelp to get to the rocks beyond while the surge is trying to pull you back out is an art form in itself.

The choir. We're not quite sure what this trumpeting is for - other than perhaps making one's presence known. The urge to trumpet bounces between birds so that it is hardly ever quiet in an Erect-crested penguin colony.

Mapping new tawaki nests on Many Islands in Dusky Sound. Year after year we find penguins in new spots, often because people spotted a bird scrambling ashore somewhere. Slowly we are filling in the gaps on the map of tawaki breeding sites. At this rate we need several life times to find them all.

A pretty wet start to the field season proper. After loading our gear and food onto the Tutoko (and after a couple of rigs were installed for a film crew that will join us in a few days) we were off. When we got to Seymour Island the rain stopped just long enough to do nest checks on the island.

Meet Peter, one of the Erect-crested penguins that volunteered in our pre-moult satellite tracking study this January. The penguin left its fledgling chick and went on a 1,000 km journey. Peter returned on 29 February, just in time for the albatross team to take off the device!
