This flock of Ichthyaetus hemprichii was on a beach on the island of Masirah in Oman. I saw them a few years ago. The species is least concern on the Red List but numbers are decreasing.
Main threats are oil and gas drilling, industrial and military effluents and egg collection. The sooner we humans stop using fossil fuels the better for the whole planet. (https://www.iucnredlist.org/species/22694303/132539775#threats)
