Hi Where I work we have had 2 pigeons that have made a nest behind a storage container. 3 weeks ago they had 2 eggs which have now hatched, the birds a looking after them ok, but on closer inspection one of the birds (We think it's the mother) has a red ring around one leg. What we wont to know is could this be long to someone and has strayed off. If so is there anyone we need to contact.
