The tiny ruru, or morepork (Ninox novaeseelandiae) is native to Aotearoa, but not endemic (i.e. it is found here, but also found in other countries). On average, it measures about 29 cm and weighs 175g.
These nocturnal creatures mainly snack on insects, but can take out small birds, rats and mice. They are perfectly designed birds of prey, with heads that can swivel 270° and softly fringed wings to silence their flapping wings.
Phil says that ruru are susceptible to poisoning as they hunt poisoned dead rats and mice. However, he says, "My observations tell me that they bounce back quite quickly."
Rurus nest in cavity, making them easy prey for sneaky stoats and possums - but the birds are classified as not threatened.
Aotearoa was also home to another species of owl, the larger laughing owl, which became extinct in the 20th century. We also have an introduced species of owl.
