Ōamaru Penguins has an ever-growing population of kororā. Every week, our staff visit the nesting boxes to record how many penguins are living here, creating detailed records of every bird in the colony and their breeding success. We identify the individuals through microchips, similar to those used on cats and dogs. Dive into the data and see how our colony is growing.
Some of our penguins have achieved impressive feats! See if you can spot them in the data visualisations above.

Another way we learn about the penguin breeding colony is to count the number of penguins that arrive home each evening. The number fluctuates throughout the year, especially early during the season when the penguins are laying or incubating eggs.
The number of penguins arriving ashore becomes more consistent when they are feeding chicks.
The peak arrival each night has risen from 42 to over 300.
