Artie,I have always been against ringing,that what it is called over here in uk,I know of a bird ringer ,who is a official ringer for eastlancs,the local tv company made a film about him ringing,they went to a peragrine site near to were I live,the climber went down to the nest site,put the chicks in a bag,they wer lifted up,all the chicks were alive when they wer put in,when they took them out to ring them,one was dead,they did not show this or mention this in the film.I was told this by a wildlife officer for that area,off the record.thanks.
