Abstract
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. Utilizamos sistemas de monitoreo remoto con vídeo para documentar depredadores de nidos de gorriones en San Clemente Bell (Artemisiospiza belli clementeae) y grabamos una depredación inesperada por un lagartija nocturna de la isla (Xantusia riversiana) el 22 de mayo del 2013. Este registro es el primer caso documentado de un gorrión de San Clemente Bell siendo depredado por un reptil y es también la primera documentación de una lagartija nocturna (género Xantusia) depredando un nido de ave. Además, encontramos que las lagartijas nocturnas se encuentran entre las lagartijas más pequeñas observadas depredando un nido de aves.Keywords
