Tent spawns nuts

One of my favorite things about staying at official camp sites is that the birds in the area know that humans leave crumbs.

Lured some collared doves to my tent. I hope they'll have breakfast with me tomorrow.

Now i looked up what the difference between doves and pigeons is again. I thought there was no difference other than something etymological, dove obviously has Germanic roots, pigeon is French. In German and I believe Dutch they are all called doves (taube, Dutch: duif). But then I read an article which claimed this:

All species and breeds of pigeons have 80 chromosomes while all species and breeds of dove have 76 or 78 chromosomes.

But the feral's ancestors are called rock doves? Are they just named wrong, are they not doves?

French also has the colombe word for what I guess the English call doves, and the rock doves are also called colombe des rochers but i think mostly pigeon biset..
