Also known as Madeira Petrel or Freira
Generally thought to be closely
related to Fea's Petrel, however recent molecular
anaylsis may challange this belief.
Separation at sea from Fea's
Petrel remains controversial.
Where and When
Breeding is restricted to the central massif of Madeira, an mid-Atlantic island south-west of Portugal. Entire population estimated at 250 to 400 birds, with only 20 to 30 known breeding pairs. The species is therefore listed as Critically Endangered. Breeders return to nesting grounds in late March or early April, constructing burrows on fairly inaccessible ledges. The female lays a single egg, which hatches in late July and early August. The chick fledges in late September or early October.
Was probably more widespread
on Madeira in the past but has declined because of predation by rats, cats
and humans as well as through degradation of its nesting habitat. Zino's
Petrel has been the subject of many conservation projects, including the
Freira Conservation Project (started in 1986), involving reducing predation
by rodents and cats and wardening; LIFE funded activities in the National
Park between 1994 and 1996. The breeding site was designated a Special
Protected Area under the European Union's Wild Birds Directive. The species
is classified by IUCN as Endangered and listed on Annex I of the European
Union's Wild Birds Directive, and Appendix II of the Bern Convention, and
is protected by Portuguese law.
