Demography and Populations

Population of the Paracas colonies numbers approximately 2300-4400 pairs (Jahncke 1994). Given that this species can be very numerous offshore (Murphy 1936, Spear and Ainley 2007), it is likely the world population is higher than 10000 breeding pairs and 30000 individuals (Brooke 2004).

Only known breeding population is the one on the Paracas Peninsula, but there may be others.

Offshore, subadults tend to forage further offshore (>500 km), while adults are found in greater numbers inshore (<200) (Spear and Ainley 2007).
