Caspian Gull (Larus cachinnans), 1cy, 12.9.2010, Norsminde Fjord

This 1cy Caspian Gull (Larus cachinnans) represents the first record in Norsminde Fjord.

At this age and at this time of year Caspian Gull is rather easy to recognize, especially individuals with characteristic proportions and plumage as this one. The head has turned almost white, contrasting with the boa of streaks in the lower neck. Also note the long, thin black bill, flat forehead, long neck, long wings, and dark tertials with broad white tips. The tail bar is broad, underwings are rather unmarked and white, upperwing has distinct secondary bar in contrast to coverts and restricted primary window.
