Abstract
Background
An updated checklist of the Birds of the Azores is presented based on information compiled from Rodrigues et al. (2010) and from the websites, Azores Bird Club. (2014), Aves dos Açores (2014)
Azores Bird Sightings (2014) and Vittery (2014), since 2010.
New information
The checklist has a total of 414 species, including 38 new species.
Almost
half of the species and subspecies that occur in the Azores have a
Palearctic origin, the remaining ones being essentialy Nearctic and
Holarctic species. São Miguel is the island with the highest number of
bird species, followed by Terceira, Corvo and Flores islands.
Keywords: Azores, birds checklist, species distribution
Introduction
Birds (Vertebrata: Aves)
are some of the most iconic animals. They play important roles in the
ecosystem, and since they are abundant and diverse in most urban and
rural areas, humans have established a good long-lasting relationship
with them (e.g., birdwatching, photography). However, amongst the ca
10.000 bird species which have been living on Earth since the appearance
of modern humans, many species were regionally lost or extinct, or are
endangered, especially on islands (Sax et al. 2002, Elphick et al. 2010, Rando et al. 2013, Alcover et al. 2015).
Updating a list of birds from remote oceanic islands represents an
important step towards an improved knowledge of colonization mechanisms
and migratory patterns by animals and a contribution towards the
conservation and management of insular taxa and their natural habitats.
The
Azores Archipelago is located in the North Atlantic Ocean, between
36°55’ and 39°43’ N, and 24°46’ and 31°16’ W, about 1500 km from
mainland Europe and 1900 km from North America (Fig. (Fig.1).1).
The Azores is a volcanic oceanic archipelago consisting of nine islands
and several islets of recent volcanic origin (0.25 to 8.12 My old),
which are spread over >600 km along a northwest-southeast transect (França et al. 2003).
The oceanic distribution of these islands and, as a consequence, their
relative positions, has led to the formation of the following groups:
(i), a western group, comprising the islands of Flores and Corvo; (ii), a
central group, with the islands of Faial, Pico, São Jorge, Terceira and
Graciosa and (iii), an eastern group, made up of the islands of São
Miguel and Santa Maria.
