Another update for Herring Gulls: 18 flying 2CY birds to show moult scores for early July. Most common pattern P5/P8, next P4/P7, so most birds now 5 or 4 fully grown inner primaries and still with P8-P10 juvenile or P7-P10 juvenile. Below, an image that represent the slightly advanced birds, which have shed tail feathers. See:

Other plumages and birds from June to follow soon... Hope you'll enjoy!
