Łukasz Ławicki & Peter P. de Vries have recently reviewed the occurrence of frigatebirds in the Western Palearctic (Dutch Birding 2018, vol. 40: 1-6).
The Fregatidae family includes five species: Lesser Fregata ariel, Great F minor, Christmas F andrewsi, Magnificent F magnificens and Ascension Frigatebird F aquila. Four of them have been recorded in the Western Palearctic but there are only 2 records of unidentified Frigatebirds in Morocco :
- an adult female at Massa, Souss, on10 April 2009
- a bird at Bouknadel, Rharb, on 8 January 2014
These birds were probably Magnificent Frigatebirds.
