Aestrelata Arminjoniana

Giglioli and Salvadori

Often considered conspecific with P. heraldica (which see). Apparently hybridizes with latter and also with P. neglecta in Indian Ocean#R. Monotypic.


S Atlantic, breeding on Trindade I#R, off E Brazil (Espírito Santo); also Indian Ocean, breeding on Round I (Mauritius)#R#R.

Descriptive notes

35–40 cm; 267–475 g; wingspan 88–102 cm. Polymorphic medium-sized gadfly petrel having pale, dark and intermediate morphs, always with white areas on... read more


Populations on Trindade and Round I possess apparently similar vocalizations, a repetitive series... read more


Marine and highly pelagic, rarely approaching land except at colonies. Breeds on oceanic islands,... read more

Food and feeding

Very little known; squid recorded and diet assumed to be mostly cephalopods. Foraging strategy presumably similar to that of P.... read more


Season perhaps variable, but adults visit colonies almost year-round at both Atlantic and Indian Ocean breeding stations. Breeding system... read more


Adults apparently fairly sedentary in much of range; immatures may be more mobile, dispersing over... read more

Status and conservation

VULNERABLE. Probably uncommon; few data available, but previous estimate of c. 15,000 individuals seems too optimistic, and overall population thought be just 1130 breeding... read more
