Likewise in English "dove" and "pigeon" are no species names. It is not even clear which species belong to the doves and which are pigeons. From Wikipedia:
"Pigeons and doves constitute the bird clade Columbidae that include some 300 species of near passerines. In general the terms "dove" and "pigeon" are used somewhat interchangeably. In ornithological practice, there is a tendency for "dove" to be used for smaller species and "pigeon" for larger ones, but this is in no way consistently applied, and historically the common names for these birds involve a great deal of variation between the terms "dove" and "pigeon."
In high school one of my best friends (a Cuban refugee, so a native Spanish speaker) owned an old, white Ford Falcon which he called "la paloma." As he put it one day when we were laboring up a long hill in the car, "On the good days, when this car can make it up these hills, I think of it as 'my dove.' On days like this, it's 'the pigeon.'"
Animals, flowers, trees and colours seldom match 100%.

p.s. I have no idea of the differences between a dove and pigeon.
