These birds belong to the order Charadriiformes. They are typically found around coastal areas and inland waterways, although some breed well inland. We have many species of migratory shorebirds that breed in the arctic then fly to New Zealand for our summer.
The wrybill, endemic to New Zealand, is the only bird in the world with a sideways curved bill, and it always curves to the right. It uses this unique adaptation to take aquatic invertebrates from under stones in braided rivers.
