Yellow-legged Gull michahellis 2CY, October 05 2001, Brouwersdam, the Netherlands.

The average moult stage for 2CY October michahellis: Primary P10 is fully grown and all the secondaries and rectrices are second generation and complete. Hence, the complete moult has ended. After this complete moult, a partial moult has included some of the tertials and wing-coverts.
The inner three greater coverts are fresh, grey based with a brownish tip and dark arrow-headed markings. The outer median coverts and inner lesser coverts have been replaced recently as well with similar pattern as the inner greater coverts. Most of the scapulars are grey.
