I'm still waiting for news on the colour-ringed Ringed Plovers that were noted in the Baglan Bay recently, but I get the impression that news of this bird will be returned much quicker. The International Wader Study Group website explains clearly the process and also other useful bits of information about their projects. The section which explains the code for this bird has been reproduced below. I'm looking forward to reporting back information on this bird very soon and encourage anyone with an interest in tracking ringed birds, particularly Sanderling, to visit the website on the link below.
International Wader Study Group - Sanderling Project
The first letter stands for the colour (Green =G) and the number for the position of the flag, where:
1 - on the left tibia (above the "knee")
2 - on the right tibia (above the "knee")
3 - on the left tarsus (below the "knee") above both rings
4 - on the right tarsus (below the "knee") above both rings
5 - on the left tarsus between both rings
6 - on the right tarsus between both rings
7 - on the left tarsus below both rings
8 - on the right tarsus below both rings
Note that positions 1 and 2 are not used for this project. The letters following the number stand for the colours of the rings (Y= Yellow, R = Red, W = White and G = Green) read downwards on the left leg first followed by the right leg. So G5YRWG has a yellow ring above a red ring on the left tarsus with a green flag between the two rings. On the right tarsus it has a white above green ring.
