Ringing and Results
We ring our birds in order to find out more about them.
We want to know where they go when not at Rye Meads, how long they live, how faithful they are to our site, how their biometrics may change over time, and we need to understand better how to age and sex them, especially those species where the differences are very subtle, like Wrens.
Details of birds ringed include the past two complete years with our overall totals, and comments on trends.
Results from our ringing programme come when birds are caught more than once. This can be as a result of recoveries, retraps or controls.
Recoveries are details of birds found elsewhere following ringing at Rye Meads. These may be caught by other ringers, or reported by members of the public. If you find a ringed bird, you can report it online here.
Retraps are birds that we catch that were previously ringed at Rye Meads. Whilst many retraps are routine, some can be highly significant - for example, catching a summer visitor that we had ringed the previous summer not only indicates that the bird has survived migrating to winter quarters and back, but that it has chosen to return to the same place the following year.
Controls are birds we catch at Rye Meads that were ringed elsewhere. It is always exciting to catch a control, but especially so if the bird carries the ring of an overseas ringing scheme.
Only one or two percent of birds ringed are recovered or controlled, so continuing to ring many birds is necessary in order to keep an up to date picture of migration patterns and how they may be changing in the light of environmental and climate changes.
