| Summary of Ringing Totals by County in 2011 | |||
|
Ringing and recovery totals for 2011. 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. Recoveries are reports of birds found dead, or found alive away from the site of ringing. Recaptures 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 number of recaptures and recoveries are for birds originally ringed in the county. For full details click here.
