[cobirds] Re: Caspian Tern, Cottonwood Marsh, Boulder Co

The terns are still present and fairly active, although I believe the Forster's Tern to actually be a juvenile Caspian. In flight, both birds have the blackish wingtip undersides. Really embarrassingly bad digiscope pics available for anyone interested.
