“Praya” Islet [Praia], off Graciosa, Azores

.

Hitherto overlooked in breeding colonies of H. castro in Azores because of similarity to that species; holotype collected in 1903. Recently found to differ vocally (in playback experiments does not respond to calls of H. castro), and also in timing of breeding (breeds in hot season, rather than in cool season) and timing of moult; further, mtDNA and microsatellite analysis reveals that the two are genetically isolated. If the name jabejabe (published in 1875) applies to this population, it would have priority; this requires investigation (see also H. castro). Monotypic.

Distribution:

Azores, in N Atlantic Ocean. Breeds in summer on islets of Praia and Baixo, off Graciosa. Breeding suspected also on Flores and Corvo Is, but proof is still lacking#R.

Descriptive notes

Habitat

Breeds on small islets. Forages over open ocean.

Food and feeding

Diet poorly known; thought to consist of small fish and squid (Teuthida).

Breeding

Egg-laying late Apr/early May to early Jul (in contrast to H. castro, which lays in Oct–Dec), with fledging by early Oct.... read more

Status and conservation

VULNERABLE. Restricted-range species: present in Azores Secondary Area. Global population estimated at 250–300 pairs in 1999. Because of its small population and low... read more
