"The Hawaiian Stilt is a slender wading bird that grows up to 16 inches in length. It has a black back and white forehead, and is white below; the female has a tinge of brown on its back. This endangered species has very long pink legs and a long black bill. The Hawaiian subspecies differs from the North American stilt by having more black on its face and neck, and longer bill, tarsus, and tail....
Stilts have a loud chirp that sounds like: kip kip kip." http://www.fws.gov/pacificislands/wesa/aeo.html

These guys really didn't like us. They would start their noise making every time we tried to approach them and walk, run, or even fly away from us.
