Uncharismatic Fact of the Day
Annoyed by others? Need your own space? Take a page from the snow petrel's book, and vomit! Adults, particularly nesting adults, will upchuck a special kind of stomach oil called mumiyo at potential threats like skuas. Because the petrels nest in the same place year after year, the mumiyo will harden and build up; in some places, scientists have excavated layers of vomit dating back more than 34,000 years!
