We used remote video monitoring systems to document nest predators at San Clemente Bell's Sparrow (Artemisiospiza belli clementeae) nests and recorded an unexpected depredation by an island night lizard (Xantusia riversiana) on 22 May 2013. This record is the first documented case of a San Clemente Bell’s Sparrow being depredated by any reptile and is also the first documentation of any night lizard species (genus Xantusia) depredating a bird's nest. Additionally, we found that night lizards are among the smallest lizard species ever observed depredating a bird's nest.
