Unlike many other large gulls Belchers Gull lacks the presence of primary spots and mirrors.
Belchers Gull - Larus belcheri
Adults
This in flight shot of an adult Belchers Gull was taken during a pelagic out of Lima, Peru in June 2007. Note the sharpest of images due to gloomy conditions and rocking and rolling on the boat but it clearly demonstrates the white surrounded black tail-band and the broad white trailing edge to the secondaries.
