Few years ago I was handed rings retrieved from a pigeon shoot. One had a phone number. So decides to call .The Man was from canary wharf London and the pigeon was a four year old when shot . It went missing from fraserburgh race after winning the Dunbar race a few weeks before as a yearling.It never left the liberation site ! Wonder how many do the same ? Does prove some can live happily in the wild environment which they had to do since the beginning of time. It's there natural instinct to forage . Wild birds thrive in good years and perish in bad only the fit ones survive.
