Little blue penguins
These are the smallest penguins in the world, and are found on Australia and New Zealand. While they are not considered endangered, they are losing some habitat due to urban encroachment.
This species native to the waters around Antarctica is considered vulnerable. Here are baby royal penguins on Macquarie Island, which is also home to king, gentoo and rockhopper penguins.
This penguin found on offshore islands of New Zealand is endangered, most likely due to disease, prey availability and climate change. They have seen a roughly 70 percent population decline over 20 years.
Another New Zealand penguin, this vulnerable species is strongly impacted by mammals that have been introduced to the island by humans. These two female penguins, Chalky and Milford, live at the Taronga Zoo in Austraila.
