The colourful journey of the Eurasian Collared Dove Streptopelia decaocto

In the 18th and 19th centuries Eurasian Collared Dove Streptopelia decaocto was widely considered to be wild ancestor of domesticated Barbary (domestic S. risoria), even following its recognition as a species taxonomic status source confusion. Since 1900, species' massive geographic expansion (both naturally by introduction) two taxa have occasionally met. The resultant hybridisation is probably cause large number Doves with aberrant pale colour in areas where has occurred.
