photo 6494: Yellow-legged
Gull michahellis adult, September 30 2001, Dannes, France
(50.44N,01.35E).
Note the very fine streaking on the crown in
the recently moulted head feathers. Primary P8 is fully grown. Compare the grey
tone with the Lesser Black-backed Gulls in the background. The moult gap in the
greater coverts is closed and the partial autumn moult has started in this
individual: the outer median coverts are replaced again. The new medians are
typically plain grey, lacking the bleached tone of the older adjacent feathers.
