Passage: The Laysan rail was an opportunist that fed mainly on invertebrates such as moths, Neoscatella sexnotata (brine flies), blowflies, and their larvae; plant leaves, seeds, and eggs and carcasses of seabirds were eaten when they were available. It was an aggressive bird that would fight off other species, particularly the Laysan finch: the latter is very adept at breaking open seabird's eggs to consume the contents, while the rail was much less so. Consequently, rails would linger around in the seabird colony, be on the lookout for finches which had just cracked open an egg, chase these away, and consume the egg's contents. On Midway, the rails were seen to steal food from domestic chicken. There exists no permanent source of freshwater on Laysan, and while the rails must have been able to cover their needs from the body fluids of prey and the content of eggs, they would eagerly drink from and bathe in pools of water remaining after heavy rain, or a pan of water provided by an observer.
