Avocet movements are very interesting to monitor as there as been quite a bit of exchange between birds on the continent and the UK. Mike Marsh saw the colour ringed bird (below) at Orfordness, Suffolk wearing only a yellow colour ring and a metal ring. He tried to trace this bird from the colour rings but to no avail. He later managed to read the ring number which was easily traceable.
Avocet 5239200 was ringed as a chick in the Beltringharder Koog, on the German north sea coast on 20th June 1992, making this bird 18 years old and a possible longevity record! This bird had also been colour ringed but had since lost a black, red and green ring, which is why he couldn't trace the bird via the colour rings.
After being seen several times around its natal site up to the 14th July 1992 it was next seen in May and June 1996 at Minsmere and now, thanks to Mike Marsh at Orfordness, Suffolk where it has one small chick to look after. Unfortunately we don't know where it spent the intervening 14 years.
