There's a reward out on the head of Auckland's own version of the angry birds.
Authorities are encouraging people to keep an eye out for the distinctive red-vented bulbul.
The Conservation Department is offering a $300 reward for sightings that lead to the pests being captured.
Red-vented bulbuls are originally from Asia and threaten native birds and fruit and vegetable crops.
The reward is for reliable information leading to a live bird being captured by DOC or Auckland Council staff.
It's on offer for a month from today, and people can call the Exotic Pest and Disease Hotline on 0800 80 99 66 with information.
Red-vented bulbuls are about the size of a starling.
They have a black head, a dark back, grey-white belly, and a distinctive crimson-red patch of feathers beneath their tail.
