The blue pigeons are a genus, Alectroenas, of birds in the dove and pigeon family Columbidae. They are native to islands in the western Indian Ocean.
Taxonomy and evolution
The genus Alectroenas was first described in 1840 by the English zoologist George Robert Gray with the Mauritius blue pigeon (Alectroenas nitidissimus) as the type species.[1][2] The genus name combines the Ancient Greek alektruōn, meaning "domestic cock", and oinas, meaning "pigeon".[3]
The Alectroenas blue pigeons are closely interrelated and occur widely throughout islands in the western Indian Ocean. They are allopatric and can therefore be regarded as a superspecies.[4] There are three extant species: the Madagascar blue pigeon, the Comoros blue pigeon, and the Seychelles blue pigeon.[5] The three Mascarene islands were home to one species each, which are all extinct; the Mauritius blue pigeon, the Rodrigues blue pigeon, and the Réunion blue pigeon.[6] The blue pigeons perhaps colonised the Mascarenes, the Seychelles or a now submerged hot spot island by "island hopping" and evolved into a distinct genus there before reaching Madagascar.[7] Their closest genetic relative is the cloven-feathered dove, Drepanoptila holosericea, of New Caledonia, which they separated from 8–9 million years ago.[8] Their ancestral group appears to be the fruit doves (Ptilinopus) of Southeast Asia and Oceania.[9]
The genus contains five extant or recently extinct species:[10]
- † Mauritius blue pigeon (Alectroenas nitidissimus) extinct
- Madagascar blue pigeon (Alectroenas madagascariensis)
- Comoros blue pigeon (Alectroenas sganzini)
- Seychelles blue pigeon (Alectroenas pulcherrimus)
- Providence blue pigeon (Alectroenas sp.)
Two species that became extinct in prehistoric times may have belonged to this genus:
- † Rodrigues blue pigeon (Alectroenas payandeei)
- † Réunion blue pigeon (Alectroenas sp.)
The Rodrigues pigeon (Nesoenas rodericana), now extinct, was once assigned to the genus Alectroenas, but this is now believed to be erroneous. In reality, it probably belongs to an undescribed genus, as the sternum's shape is very dissimilar in its details to that of Alectroenas or Columba, and indeed to any other living genus of pigeons and doves. It is most similar to that of the Gallicolumba ground doves or to a miniature version of the sternum of a Ducula imperial pigeon.
Description
Compared to other pigeons, the blue pigeons are medium to large, stocky, and have comparatively long wings and tails. They all have distinct mobile hackles on the head and neck. The tibiotarsus is comparatively long and the tarsometatarsus is short.[11]
