4 birds from Rutland Water (1 Viewer)

Hi guys. I think i have here a juvenile black headed gull, It has some dark tail feathers so not a Mediterranean. A tufted duck with young. Some young swans, as although I have never seen them that developed the shape and grey colour must be a swan ? The other duck I think s a female Gadwall although a Mallard is possible. Not sure on the difference on the eye stripe and colouring ?

Thanks for any help.

photos please Mike Tom
