photo 5710: Yellow-legged
Gull michahellis adult, July 30 2001, Le Portel, France
(50.44N,01.35E).
Primary moult score: P8-P10 still old and P6
just over P5 (hence P6 classified fully grown in our scores).
The inner greater coverts (#5-#9) are growing,
exposing the secondaries, with their white tips. As can be found in most birds,
the two mouilt waves in the greater coverts meet at about #8. One moult wave was
initiated in the outer-wing, and one moult wave started at greater covert #1,
the innermost feather.
