Not another shorebird! Yes sir, number 11 is the amazing Wrybill, resident of New Zealand, and an evolutionary marvel. Not the best looking bird on my bucket list but surely one of the most bizarre looking.

The Wrybill is a species of plover that is endemic to New Zealand. It is the only bird in the world that has a beak bent sideways. One would think that this unique adaptation allows the plover to reach tasty morsels more easily, especially under pebbles and stones on fast flowing rivers. On the mudflats Wrybills sweep their bill from side to side much like an avocet or spoonbill does. Some ornithologists in NZ believe that for much of its time the Wrybill doesn't really need to have this uniquely shaped bill in order for it to feed. So it begs the question, why does it have such a peculiarly shaped bill? The feeding adaptation is the only conclusion I can come up with. Maybe its preferred habitat was much more prevalent in years past and the adaptation was more necessary. Maybe its main food source on the breeding grounds requires this adaptation more than is required on more traditional shorebird feeding habitat, such as mud flats. Fascinating bird and a lot more to learn from them, I'm sure.

They nest on the south island, mostly around Canterbury, and then fly to
the north island to spend the winter. They require large shingle beds,
up to a quarter mile in size, which are created and occur alongside fast flowing rivers. This might be one of the main
reasons why it's breeding range on south island might be so small, as
that habitat is scarce. Wrybills nest on the open shingle and typically lay 2 eggs, which look just like the pebbles upon which they lay. Even as an embryo baby Wrybills have a pronounced bend in their bill!
After the breeding season Wrybills form flocks and head north, frequenting harbors and mudflats on the north island. I've always wondered whether their bills give them problems during
flight? Out of all the birds on my bucket list, I find the Wrybill the
most fascinating from an evolutionary standpoint. Aren't they cool?
