Some recent considerations might be:
Alain Bavencoff's FR 98-353622 which in 2009 placed 392nd International Barcelona out of 26779 birds, as an 11 year old. This bird flew 1036,602 km at 882,94 M/M and was his first bird home (his second pick bird) out of 11 entries. I would suspect that this bird had some road sense and even at 11 years of age (if you believe the band number) was highly thought of by Alain Bavencoff
Kurvers - De Weerd's NL 99-1361873 which in 2007 placed 20th International Barcelona out of 25716 birds, as an 8 year old. This bird flew 1096,692 km at 1260,16 M/M and was his first bird home (thirty-second pick bird) out of 39 entries. I would suspect that this bird performance was as much a surprise to Kurvers - De Weerd as it was to everyone else. Though it really should not have been as NL 99-1361873 has proven to be a very durable pigeon from Barcelona http://users.skynet.be/fb168503/Cureghem/2008/barca9808.htm
