The Axe Estuary Ringing Group has two active colour-ringing schemes;
Every Black-tailed Godwit colour-ringed on the Axe Estuary is fitted with six colour rings, with the combination of YELLOW RED YELLOW on the birds right leg being the Axe Estuary's unique colour-ring combination. The colour-rings fitted on the birds left leg are unique to each individual bird.
Birds are named by the first letter of each colour ring on their left leg from top to bottom, for example yellow over orange over green would be known as YOG.
A yellow darvic ring with two letters is fitted on the birds left leg, with the standard BTO metal ring placed on the birds right leg.
Once again, if you see any of our colour-ringed birds, even if it is on the Axe Estuary, please email the full details (date, time, location, species and colour-ring combination or code) to email@example.com
