The Group studied chick survival at a number of sites on the Norfolk coast during the 1990's.
All were colour ringed with 2 colours on the tibia of one leg and a yellow over metal ring on the tibia of the other leg.
Lots of sightings of our colour ringed birds have occurred, Many of them in the south-west on the Tamar Estuary where many Avocets are known to winter. Others have been seen in France and in Holland.
Colour ring sightings provide some fascinating life histories of individual birds.
Map of Avocet recoveries and colour ring sightings.
Many of these Avocets are still alive and some
new longevity records
for this species. If you see a colour ringed Avocet please send details of
when and where you saw it to John Middleton (including a grid ref or
co-ordinates if possible). Full details of the life of an individual will be
sent to you if the combination you saw matches one in the Group Database.
