Pterodroma deserta


, 1934,

Bugio Island, Desertas Islands, off south-east Madeira


This taxon was previously considered dubious and the population included within a monotypic P. feae (itself sometimes treated as conspecific with P. mollis). It has recently been accorded rank of full species on basis primarily of molecular data#R, although there are also differences between the two in bill morphology (slight, allow 1) and vocalizations (seemingly moderate, but possibly decisive, so 3); moreover, there is a marked difference from P. feae in timing of breeding (Jul–Aug vs Dec–Jan) (currently unscorable on system used herein, but clearly important). Treatment as separate species is here provisionally accepted on the basis of remarkable disjunction in breeding season and other characters. Monotypic.


Atlantic Ocean, breeding on Bugio I, in Desertas Is, off Madeira#R. Recently recorded a few times in Azores#R.
