Two shots of Black-headed Gulls which I like for different reasons. The first shot has an intimacy, as if we have strayed into the bird's domain and the chocolate brown of the bird's head is nicely echoed in the background. The second image, I think, is made by the quality of the light, the halo effect on the bird's wing tips, the reflection in the water and the apparent concentration in the gull's eyes.
