Night sounds

I took this video clip just after dusk, I wanted to show what is sounds like. It was pretty windy as you can tell from the tree, most of what you see flying around and hear are the Bonin Petrels. They are a nocturnal bird that digs burrows in the ground and come out by the thousands just as the sun goes down. Many places on the island are so saturated with their burrows that you can't walk without caving one in. If you do step in one you have to dig it out so you don't trap the birds inside. Apparenly they can't dig themselves out.
