I have had about 15 stray old birds this season here in Moffat.In each and every case I have tried to contact the fancier (mostly Lanarkshire and Midland,one from the Netherlands).With the exception of two fanciers everyone contacted has said wait a couple of days and chuck them up.I fully understand the cost of retrieving pigeons and I have no judgement to make on anyone.So what I do is put them in a basket and drive up the motorway to Abington and toss them there, not ideal I suppose but it at least gives them a start to get home.
