Thank you very much

Very interesting, especially with the bill colour. I was aware of the yellow bill during breeding, but not that it was the difference between the male and female during the summer or breeding as I say.

So this is a juvenile turning in to an adult winter plumage, FIRST WINTER and next spring the bill will be yellow or black depending on the sex

Thank you very much again
