Argentatus vs michahellis part. 2, 19.10.07

Publié le par Stéphane Aubry (

The ad. Herring Gull is still present. After 2 weeks, its appearrance has changed. It lost its P9 and P10 and its growing P8 is longer (1). It lost some outer secondaries and rectrices.

In the water it is now shorter winged than michahellis (2) and in flight its wings look "incomplete" with the missing secondaries (unlike michahellis).

All the pictures of this bird are visible here (and following ones).
