There are pigeons, dove dove and pigeon, but there was a general term to describe it as a dirty bird, but how do foreigners say about pigeons? I can't remember!
difference between dove and pigeon:
There's no difference between a pigeon and a dove in scientific nomenclature, but colloquial English tends to categorize them by size. Something called a dove is generally smaller than something called a pigeon, but that's not always the case. A common pigeon, for example, is called both a rock dove and a rock pigeon.
