Streptopelia

Collared Dove ( Streptopelia decaocto )

The turtle-doves ( Streptopelia ) are a genus of pigeons birds with about a dozen species.

Features

The turtle doves are usually smaller and more slender than the field pigeons (Columba ). In addition, they have a longer, keilförmigeren tail. The plumage is brownish in most species. However, many species have black and white spots. Characteristic of the species are white or black neck Bring, side of the neck spots, black ear patches or black spots on the wings. The beak is stretched.

Dissemination

Center of their range is Africa, but several species also occur in the mainly tropical Asia. The Turks and the turtledove are two representatives of the turtledoves, which are also found in many parts of Europe since the early 20th century. In particular, the collared dove has significantly expanded their range in recent decades and is now well on the avifauna of Britain, where it has not been represented in the 1960s. The turtle doves are migratory birds of temperate climate zones in most cases.

Stock development

In contrast to the collared dove, which has expanded its area of ​​distribution, population trends of the turtledove is declining. According to a study published in 2007, the EU, the turtle-dove is one of the species whose stock has fallen in the last 25 years by 62 percent. The population decline is attributed to changes in agricultural practices and the decline in Erdraucharten that play a major role in the diet of turtle doves. The population decline due but also the shooting of pigeons in particular in the Mediterranean during their migration periods.

Species

The turtle doves are within the order of pigeons birds to the subfamily Columbinae. The genus can be attributed to 13 species:

• Kichertaube (p. bitorquata )
• Kapturteltaube ( S. capicola )
• Collared Dove (p. decaocto )
• Glasses Dove ( S. decipiens )
• Adamawa turtledove (p. hypopyrrha )
• Trauerturteltaube ( S. lugens )
• Orientturteltaube (P. orientalis)
• Reichenowtaube (p. reichenowi )
• North African Turtle-Dove ( S. roseogrisea )
• Crescent Dove ( S. semitorquata )
• Wine Red neck ring dove ( S. tranquebarica )
• Turtledove (p. turtur )
• Röteltaube (p. vinacea )

In a separate genus Nesoenas were spun:

• Madagascar Turtle Dove ( Nesoenas picturata, formerly Streptopelia picturata )
• Rose Dove ( Nesoenas mayeri, formerly Streptopelia mayeri )
• Rodrigues - dove ( Nesoenas rodericana, formerly Streptopelia rodericana ) - This recently extinct ( before 1690? )
• Reunion Rose Dove ( Nesoenas duboisi, formerly Streptopelia duboisi ) - This recently died ( 1700 )

In a separate genus Spilopelia were spun:

• Palm Dove ( Spilopelia senegalensis, Streptopelia senegalensis formerly )
• Perlhalstaube ( Spilopelia chinensis, formerly Streptopelia chinensis)

In phylogenetic studies of the genus field of pigeons (Columba ) and the species of turtle doves ( Streptopelia ) in 2001, it turned out that two groups of species could be fully attributed to neither the one nor the other group. In many cases, their own classes for this species of pigeons had been built before. However, it was decided to leave them in the kind of the turtledoves, or - as in the case of the Rose Dove - classified there as they seemed to be related to this group the next. The occurring in Mauritius rose dove ( Streptopelia formerly mayeri ) and the Madagascar Turtle Dove ( Streptopelia formerly picturata ), however, were provided by Anthony S. Cheke in 1893, built by T. Salvadori for the Rose dove genus Nesoenas 2005. In the same work Cheke suggested that Perlhalstaube (formerly Streptopelia chinensis ) ( Streptopelia senegalensis formerly ) also put together and the palm dove into its own genus. He was nominated for the built of Sundevall 1872 for the Palm dove genus Stigmatopelia because they work within the Sundevalls priority over the built for the Perlhalstaube genus Spilopelia have, as they had been mentioned in the work of Sundevall first. The simultaneous release of various generic names in different places of a work -related but under Article 24.2 of the ICZN no order nor the priorities. A priority is set in the later occurrence of synonymy only by a new author ( First Reviser ). First Reviser in this case was Richard Schodde, who had erected a subgenus for the Palm dove and the Perlhalstaube already in 1997 and selected the name Spilopelia for this. The genus name Spilopelia for both types has now become widely accepted, however, some systematic follow the division Sundevalls in two different genres.
