First record of Black-capped Petrel (Pterodroma hasitata) for Morocco

By MaghrebOrnitho | 18 November 2017

During one of his marine surveys off the Moroccan coast, Andy Williams photographed a Black-capped Petrel (Pterodroma hasitata) flying c. 30 km off Agadir on 23 March 2013. However, he ignored the photo and it wasn’t until last summer when the bird was identified.

The ‘WP reports’ (Ławicki & van den Berg 2017) in the last issue of the Dutch Birding mentioned the bird: “A recently discovered photograph of Black-capped Petrel… off Agadir…concerned the first for Morocco.”

This is indeed the first record for Morocco, and according to it’s the first record also for mainland Africa and the 8th for Western Palearctic (WP). With only 9 records to date (see, the species remains one of the rarest visitors to the WP.

The species is polymorphic (distinct populations) with black-faced and white or light-faced morphs are well known and studied. An intermediate morph is also known (but less understood), and the Moroccan bird is apparently from this morph.

See Neotropical Birds Online (Cornell Lab of Ornithology) for information about the species, and this blog about variation in plumage (well illustrated with several photos).

Andy Williams thanks ScillyPelagics for ID assistance, and we think both for this nice addition to the Moroccan birds list.
