Lesser Black-backed Gull (graellsii & intermedius)

(last update: May 17 2015)

Lesser Black-backed Gull intermedius NOS 4196602 9CY, October 04 2002, Boulogne-sur-Mer / Le Portel, NW France.

An adult bird metal-ringed right 4196602, the code was read but the country name not. Match to a bird ringed as pullus in 1994 at Vest-Agder, Norway (thanks to Morten).

Primary moult stage: P5 fully grown and P8-P10 still present. A strong and more powerful intermedius (maybe a male) with an attenuated rear, long neck and long bill, somewhat cachinnans-like in general appearance.
