Black-tailed Godwit (Limosa limosa). Bowling Green Marsh. 10/11/07
White, (Dark) green / yellow, white. Note the discolouration on the left leg's white ring which is regularly in the water. As the rings age, it can get a little tricky to distinguish white and yellow, especially at distance or under less-than-ideal conditions. Bird was ringed as an adult in August 1996, so now at least 12 years old.
