These are Nenes, the state bird of Hawaii.  Sometimes called the “Hawaiian Goose” it’s related to the Canada Goose most of us see crapping up our parks and lawns.  It lives only on the Hawaiian Islands and very nearly became extinct before Hawaii could even become a state.  Those invasive mongooses had a big impact on the ground-nesting Nene but habitat loss and over hunting by humans didn’t help either.  In the 1950’s, the wild population was down to only a few dozen individuals.

Captive breeding programs and culling of their invasive predators have allowed them to bounce back.  Today Nenes are even recolonizing on their own islands they were wiped off of decades ago.

I spotted a group of four grazing a lawn at Hawaii Volcanoes National Park.  There was no indication of their dance skills.  😉 (Ask your kids.)
