Wright’s skink is a generalist scavenger and predator, largely dependent on seabird colonies where it feeds on insects attracted to dropped fish, and on the eggs and chicks of the birds (1) (4). It feeds heavily on these items, putting on much weight in the seabird breeding season. For the rest of the year it survives on declining insect populations. Its large size enables Wright’s skink to store large fat reserves sufficient to survive several months until the seabirds return to their breeding colonies (4).
Little is known about the biology of Wright’s skink, although we do know that this skink is an egg-laying species (1). Eggs of skinks are usually laid as single clutches, and may be guarded or abandoned, but in some species they are laid communally. Clutches are typically small in this lizard family, and limited to just one or two eggs in some species (3). Most skink species are diurnal, although some are nocturnal or crepuscular (3).
