The rock dove is 30 to 35cm long with a wingspan of 62 to 68cm and weighs 238 to 380g in the wild or feral state, though overfed domestic and semi-domestic birds can exceed normal weights. Eggs can be laid up to six times a year. It may have been domesticated as long as 5,000 years ago (Wikipedia, general species account).
Wild birds are the ancestors of the familiar domestic pigeons and of feral city pigeons. The sources opened for the Bhutan guide give only these measurements and breeding facts, so nothing is stated about where in Bhutan it occurs.
