A yellow-eyed penguin has been spotted giving a sea lion a good talking-to.
The photos, tweeted by Urban Nature Dunedin, were taken at a beach on the Otago Peninsula.
Despite the sea lion having a considerable advantage in terms of size, the penguin showed no signs of intimidation.
At just 65cm tall, this penguin had no trouble giving a hapless sea-lion a piece of its mind.
Its behaviour is true to the Maori name for the species, 'hoiho', which means noise shouter.
Yellow-eyed penguins are one of the world's rarest penguins, and are native to New Zealand.
Just 150 pairs of the penguins were left in the early 1990s, but that number climbed to an estimated 442 pairs by 2011 thanks to conservation efforts of groups like the Yellow-Eyed Penguin Trust.
They may be small, but these photos prove the penguin is anything but shy.
