Population justification: On Española, the breeding population was estimated at c. 12,000 pairs in 1970-1971, 15,600-18,200 pairs in 1994 and at least 34,694 adults in 2001. On La Plata Island, there are probably fewer than 10-20 pairs.

Trend justification:

On Española, the overall breeding population was considered to have been stable during the 20th Century, yet Awkerman (2006) showed that adult survival declined between 1999 and 2004. These findings were supported by Anderson et al. (2008), and there is evidence that the population has declined between 1994 and 2007. Recent estimates at Punta Cevallos track declines in the numbers of breeding adults at a mean of 2.3% per annum since 1994, and 6.3% per annum since 2007 (Street 2013). Thus the species has potentially undergone rapid population decline, placed here in the range 30-49% over the past three generations (c. 85 years). The ongoing rate of decline could be even greater, but given the long generation lengths used these too are tentatively placed in the range 30-49% over three generations.
