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. Ilikuwa ni ndege mkali ambaye angeweza kupigana na spishi zingine, haswa mfinyanzi wa Laysan: mwisho ni mjuzi sana katika kuvunja mayai ya ndege wa baharini ili kutumia yaliyomo, wakati reli ilikuwa kidogo sana. Kwa hivyo, reli zingebaki kuzunguka koloni ya ndege wa baharini, kuwa kwenye mlinzi wa finches ambayo ilikuwa imevunja yai, kuzifukuza, na kutumia yaliyomo. Katikati ya njia, reli zilionekana kuiba chakula kutoka kwa kuku.
