Population justification: The breeding population is estimated at 110,000 pairs (Jennings 2010) (330,000 [Jennings 2000] to fewer than 500,000 [H. King in litt. 2005] individuals).
Trend justification: In the northern population, c.12 colonies have become extinct (Symens et al. 1993, Aspinall 1996, H. King in litt. 2005) since the 1960s, representing a potential loss of up to c.80,000 pairs. In Saudi Arabia, the number of breeding pairs declined by more than 75% during 1980-1992 (Symens et al. 1993). Declines are thought to be continuing due to coastal development, egg and chick collection (Wilson 2012) and marine pollution; and are placed here in the range 30-49% over three generations (c. 26 years).
