LARGE GROUPS OF SWANS


I have been told about large numbers of swans in the fields in the Mablethorpe and Huttoft areas. These birds are Whooper swans that have come down from Iceland. The key difference in identity between our Mute swans and the winter visitor Whooper swans is the colour of the beak. Adult Mutes are orange whilst adult Whooper swans are yellow. The two species are about the same size as the photograph that I took at Mistley walls in Essex a few years ago shows. There are Canada geese and Black-headed gulls in the background. R W

  1. How do you tell a black-headed gull when it hasn't got a black head?
    It still has a black spot behind its eyes.
