98% of pigeons and doves do not make it through 365 days of life.
That’s in the wild.
Pigeon pets can live past 20 years. One of mine died at 12; the one I have now is going strong at about 14.
Actually, I had mixed feelings when the homing pigeon died; he was never happy - he was a rescue and had flown; and I got him too late.
The feral, gotten before fledging, is a jolly guy, and I’m convinced he wants to beat the 20-year mark.
