Black-headed gulls are in the process of regaining their black (more chocolate-brown really) heads. These noisy and sociable gulls can be seen in almost every park and lake in the UK. Losing the dark colouring in winter, you can see all stages of their plumage-change at present, among different individuals. I was photographing these on Galley Hill, when a young man stopped his cycle-ride to ask what I was photographing.
He frightened the gulls away but never mind- he hadn’t realised they change over the seasons. He cycled off, then returned up-hill to ask if it was true of males and females- it is! Conditions: Heavy cloud, high winds and rain later. Temperature: Max 11- Min 7C.
