Assessment rationale/justification
This species has a large breeding population in the UAE, which is in rapid decline, meeting the threshold for listing as Endangered. However, the breeding population in the wider Arabian Peninsula is stable; thus, the potential for immigration from outside the UAE remains very high. Therefore, the species has undergone a regional adjustment (of one category) and is listed as Vulnerable at the national level.

Threats listed in assessment
Across its global range, egg collection is believed to have caused rapid declines in a number of breeding colonies, with the population on Sheedvar Island (Iran) noted as falling from around 300,000 pairs in 1972 to fewer than 30,000 in 1977 (BirdLife International 2018). Egg collecting is believed to continue but at a reduced rate as the market for eggs reduces (Jennings 2010), although in 2016 it was noted that this practice is again increasing within UAE (Environment Agency - Abu Dhabi 2016). Other threats to UAE colonies include predation by introduced mammals, oil pollution and marine debris (plastic), tree planting, irrigation, development and disturbance (Aspinall 1996).

History
The population would have been at least twice as large and there is no indication of decline at the time, hence it is assessed as Least Concern in 1996.
