One thing I learned about Petrel chicks of both species is they projectile vomit in self-defense. Our friendly ornithologists got covered in the stuff, with one receiving a direct hit in the face... yum. My job was to help locate nests and write down the tag numbers. Even though I did not have to reach into the rocks to extract the chicks (I would not have known how to do so without hurting them) I still managed to get vomited upon.
Other notable events today: first sighting of Emperor Penguins in the archipelago and a partial solar eclipse.
