Population justification: The extrapolation of survey results obtained in 2005-2006 suggests a population size of 14,436 mature individuals (95% CI: 13,376-15,492).  Studies involving more recent fieldwork have provided much lower estimates of 1,035 individuals (95% CI: 832-1,287), which may be an underestimate owing to the methods used, and 550-950 pairs, which may have been affected by drought conditions during part of the study period (B. Nicolai in litt. 2011).  Until further research is carried out, an estimate of 13,400-15,500 mature individuals is used here.

Trend justification: Although the population estimate published by Seoane et al. (2010) greatly exceeds the estimate provided by Bibby and Hill (1987), this is not necessarily indicative of an increase as differences in methodology mean that such estimates are difficult to compare, and the earlier study may not have properly considered detection probability (Seoane et al. 2010).  Development for tourism remains a threat but its rate has probably decreased in recent years; however, overgrazing by livestock appears to be increasing and is thought to be impacting the species through habitat degradation (A. Iñigo in litt. 2011), thus the species is suspected to be declining as a consequence of on-going habitat loss and degradation.
