Record the species - Red Knot, Great Knot or Bar-tailed Godwit.
Record flag colour and position - In these examples the leg flags are yellow and are recorded as YLF (Yellow Leg Flag) / UL or UR (Upper Left or Upper Right). An alternative is to use numbers to denote the flag postion, as in the colour band chart.
Record band colours on the bird's left leg - upper and then lower.
Record band colours on the bird's right leg - upper and then lower.
Remember that records are relative to the bird (left or right), not relative to your point of view.
