Ringing and recovery totals for 2010. Pulli are birds ringed in the nest, juveniles are those identified as being in their first calendar year, adults are all birds in their second or later calendar year. Some birds cannot be aged by plumage characteristics, these unaged birds are tabulated separately and are included in the totals for the year. A few birds (mostly scarcer raptors) ringed at confidential locations have been excluded from the individual couty totals, but are included in the country totals.
Recoveries are reports of birds found dead, or found alive away from the site of ringing. Retraps are reports of birds found alive, generally within 5km of the ringing site, but for Storm Petrel (20km), Mute Swan and Canada Goose (40km), common shore waders (30km), gulls (40km) and Sand Martin (10km) this threshold is greater. The column of Grand Totals refers to Britain & Ireland, it is not possible to calculate this for individual regions. For full details click here.
