The Rodrigues pigeon or Rodrigues dove (Nesoenas rodericanus) is an extinct species of pigeon formerly endemic to the Mascarene island of Rodrigues. It is known from a subfossil sternum and some other bones, and the descriptions of Leguat (1708) and Julien Tafforet (1726).




Taxonomy



This bird was assigned to the genus Alectroenas, but this was erroneous. It is most similar to that of the ground doves (Gallicolumba) or to a miniature version of the sternum of an imperial pigeon (Ducula). If this similarity is not based on convergence, considering the evolutionary relationships of the dodo and the Rodrigues solitaire, the Rodrigues pigeon is quite possibly the closest relative of the Raphidae that was still alive in historic times. This does not mean that there is any close relationship between this bird and the didine pigeons, only that both derived, independently, from the same Indo-Asiatic lineage, which became extinct millions of years ago.
Two tarsometatarsi were attributed to this species. Today, they are believed to represent another taxon, closer to the Malagasy turtle dove (Nesoenas picturata), and thus the name Rodrigues turtle dove also refers to the present species.




Description


It was a bird the size of a tambourine dove and colored slate grey. Leguat and his companions took a fancy to these tame and confiding birds and had several dozen birds attending their outdoor table at mealtime to wait for scraps; they were especially fond of melon seeds. In 1693, the bird was found foraging on the island, but nested only on offshore islets which the rats that had been introduced at some time in the 17th century had not yet reached.




Behaviour


Leguat described its behaviour as follows:

The pigeons here are somewhat less than ours and all of a slate colour, fat and good. They perch and build their nests upon trees; they are easily taken, being so tame, that we have had fifty about our table to pick up the melon seeds which we threw them, and they lik’d mightily. We took them when we pleas’d, and ty’d little rags to their thighs of several colours, that we might know them again if we let them loose. They never miss’d attending us at our meals, and we call’d them our chickens. They never built their nests in the Isle, but in the little islets that are near it. We suppos’d ‘twas to avoid the persecution of rats, of which there are vast numbers in this Island...
Tafforet described its behaviour as follows:

The turtle doves there [Rodrigues] are in great numbers, but on the mainland one sees very few, because they go to feed on the islets to the south, as do the parrots, and come to drink likewise on the mainland [Hume's translation].




Extinction


Tafforet's report is the last record of this species. It can be assumed to have gone extinct in the mid-18th century, when rats finally overran its nesting sites.
