Population justification: It is generally scarce and difficult to locate even at known sites, with the exception perhaps of Yemen (R. Porter in litt. 2006). Its population is approximately estimated to number c.3,000 pairs, i.e. c.6,000 mature individuals and c.9,000 individuals including juveniles and non-breeders. This comprises 500 pairs in Saudi Arabia; 500 pairs in Oman, although this may be optimistic (J. Atkins in litt. 2006), and c.2,000 pairs in Yemen (M. Jennings in litt. 2006).
Trend justification: R. Porter in litt. (2006) indicated that the species is possibly declining.
