Rehabilitated guillemots - Notable Ringing Recoveries
During the period 1993 to 2003 (inclusive), we ringed 1064 Guillemots and 60 Razorbills.
To-date there have been 43 ringing recoveries (42 Guillemots and 1 Razorbill).
21 (almost 50%) of the ringing recoveries are for birds that have been recorded as surviving over a year after their release.
2 guillemots have been observed on breeding colonies - the first was on Skomer 751 days after release.
The second on Puffin Island, Anglesey, this guillemot has been recorded for 3 years running - first in June 2011, then 2012 and 2013. On each occasion it was "intentionally taken" by monitors of the colony and measurements recorded. It had been released by SDST in March 2003 so we know that this bird is now over 10 years old.
Two of the latest ringing recoveries for rehabilitated oiled Guillemots, are also the longest to date - they were both found during violent storms that lashed the Atlantic coasts of Spain, France & the UK.
The first was found at Jard-sur-Mer, France on the 8th February, 2014, a distance of 471km and 4996 days after its release by this Trust at Hopes Nose, Devon on the 5th of June, 2000.
The second was found at Getaria, Spain, on the 23rd February 2014, a distance of 801km and 5456 days after it had been released by this Trust at Hopes Nose, Devon, on the 9th of March, 1999
These two latest recoveries were amongst many thousands of seabird that had been affected by continuous violent storms.
