PREFACE
This is the sixth edition of the Illustrated key for Black-tailed Godwit colour
ring schemes. The information was updated, new schemes added, and
names recoded – unique country schemes and centraly coordinated schemes
were renamed with the two-letter country codes.
As on previous versions, schemes without confirmed information were not
included. They will be included as soon as information about them became
available from ringers and scheme coordinators.
This version includes some schemes with no ringed birds from programs
expected to begin running on 2015.
Schemes with birds ringed only on XX century were removed, with exception
of RSPB1 that is known to still have at least one bird alive.

NOTES ABOUT SIGHTS
(Things to have in mind when seeing a ringed bird)
Discoloured rings – some colours can change with time or became dirty.
White is the most problematic colour, as it easily turns yellowish, or even
reddish. On other hand, light-coloured rings can became whitish.
Some colours are difficult to distinguish, specially with poor light conditions.
The most easily confusing colours are:
dark green - dark blue - black;
yellow - orange – red;
light blue (pale) - light green (lime)
Ring size & shape - It’s important to pay attention on the size and shape of
rings. Most observers don’t care about it, but in some cases this is important
to scheme identification.
Flags - From the wrong angle, flags-rings can appear as a normal colour ring
(more easily than thought!)
Engraved rings – some rings have one or more letters and/or numbers on it
Tarsometatarsus rings - below ankle (“knee”) rings are difficult to see,
specially small dark rings.
Lost rings –not common, but some cases are known to happen.
Don’t forget! Bird’s left leg it’s only on your left side if you are looking the bird
from back

HOW TO INTERPRET THE DRAWINGS
Each drawing indicates all possible combination of rings to the representedscheme. Figure 1 explains a hypothetic scheme.
Grey arrows – indicates rings that could have alternative positions andindicates the possible positions it can be.
A Multicolour ring represents a ring position that could receive severalcolours. The multicolour ring is painted with all possible colours for thatparticular position.
On drawings’ right side is showing all possible colours to all positions. Metalring is only present on right side if included as part of the scheme.
L and R refer to Left and Right bird’s legs. When both L & R are on both legs,the leg on drawing’s left side could be either the bird’s left or bird’s right legand the same for the leg on drawing’s right side.
Drawings were done on scale when information about ring size is available(drawings without the 5 mm scale symbol aren’t on scale).

REPORTING SIGHTS
WHERE TO SEND OBSERVATIONS
Information on sights should be sent to the ringer and to the NationalRinging Centre of the country were the bird was observed. If you don’t knowwhich ringer should be contacted, you can send it to the International WaderStudy Group (IWSG) or to the EURING.
COLOUR CODES
Colours are represented by letters. Most people use the coding from EURINGbut others codes are also used, which unfortunately can result inmismatches. Table below lists the codes for the 9 most commonly usedcolours and 5 barely used colours. Grey can be light or dark but there’s noindependent code.

SYSTEMS OF REPRESENTING RINGS COMBINATIONS
There are several ways to write ring combinations. This section describedsome of the ways used to report Black-tailed godwit sights.
Absolute positions
Figure 2 shows absolute positions of rings. This system is mainly used ondatabases but it could helps to understand the filling of webforms and bywhat we mean by Above Knee1 and Below Knee. In this case, and inopposition to all others systems, rings are read down-up
Figure 2 – Absolute positions explanation based on a hypothetic scheme. Each leg has 3possible positions on tibia (above knee) and 3 on tarsus (below knee), even not allpositions must effectively have rings. Positions are numbered upwards and include metalrings. In this example there’s only one ring on right tarsus, on position RB1, and 2 on lefttibia, Orange on LA1 and Red on LA2, while left tarsus and right tibia have all 3 positionsfull.
1 It’s usually referred as knee or ankle but has no exact match on human’s anatomy. It splits the leg in
tibiatarsus (commonly referred as tibia) and tarsometatarsus (commonly referred as tarsus)

IWSG system
Always begin by left leg rings. Rings on left and right legs separated by a plus(+) or a minus (-)Above and below knee rings are separated by a slash2 (/)Each ring position separated by a comma (,)Rings written from top to downSee figure 3 for examples
Simplified system
Same as before but with no commas. Usually rings on left and right legsseparated by a minus (-)See figure 3 for examples
Simplified computer friendly system
Same IWSG, without commas, always a minus (-) for legs and a plus (+),instead of splash (/), to kneeSee figure 3 for examples
RUG3 system
Only applies to the RUG schemes (Netherlands). First letter is the flag colourfollowed by a number that gives flag position. Then all other 4 rings fromdownwards, first left then right leg.See figure 3 for examples
2 Some people uses two slashes (//)
3 University of Groningen, Netherlands
