During the last 10 days I've being having a colour-ring reading extravaganza at Shawell. I've made about 80 readings and for once I'm seeing the birds close. Norwegian Lesser Black-backed Gulls (Larus fuscus) made up a significant percentage of the colour-ringed gulls recorded; including the first juvenile. Caspian (Larus cachinnans) and Yellow-legged Gulls (Larus michahellis) are giving themselves up a little easier at present, as they are already carrying out there post-juvenile moult, whereas most Herring (Larus argentatus) and Lesser Black-backed Gulls still in juvenile plumage. Some of the latter two, however, are moulting a few scapulars, so care has to be taken.

The gull below gets me going every time, as I think I have a Yellow-legged Gull with a colour-ring. However, A+G is a hybrid (parents LBBG and LBBG x HG). Ringed in Gloucester as a chick in 2014.
