Gallery: cachinnans 2cy january-june
Species: larus cachinnans

from the uncertain gallery: "can we asses such birds only from underside view to species? is this the pale extreme of michahellis? bill looks on the short and robust side and tail band reminds me more of YLG, tapering at the outer corners."
but it is 1. pale 2. has secondary bands on rectrices 3. very long p10 tongues for a 1st cycle - should be caspian.
