A large sign board has been installed in the Ames St Reserve, Paekakariki, to alert people to the fact a small population of little penguin, also known as korora, reside there.
The little penguin have nested in parts of the reserve, especially in the cliff face, as well as under some homes in Ames St for many years.
The sign, installed by the Kapiti Biodiversity Project, is an attempt to alert people to the species' vulnerability and the need to protect them from dogs in particular.
Kapiti Biodiversity Project programme manager Glenda Robb said some of the houses and sheds in the street had little penguins nesting under them "for 40 years".
The population was small, about a dozen birds, she said.
