, often referred to as the typical pigeons. The terms "dove" and "pigeon" are used indiscriminately for smaller and larger Columbidae, respectively. Columba species – at least those of Columba sensu stricto – are generally termed "pigeons", and in many cases wood-pigeons. The species commonly referred to just as "the pigeon" is the Feral Pigeon

Latinisation (literature)
Latinisation is the practice of rendering a non-Latin name in a Latin style.

Systematics

The American pigeons formerly in Columba are now split off as a separate genus Patagioenas
Patagioenas
Patagioenas is a genus of New World pigeons whose distinctness from the genus Columba was long disputed but ultimately confirmed. It is basal to the Columba-Streptopelia radiation. Their ancestors diverged from that lineage probably over 8 million years ago...

Streptopelia
Streptopelia is a genus of birds in the dove family. These are mainly slim, small to medium-sized species. The upperparts tend to be pale brown, and the underparts are often a shade of pink. Many have a characteristic black-and-white patch on the neck, and monotonous cooing songs.The heartland of...
