Near-adult Slaty-backed Gull (right)
with larger Great Blacked Gull viewed from the Control Gates at
Chippawa above Niagara Falls on 30 December 2012. It was on the rocky island in the
River, which is in Canada. It had a paler mantle than Great
Black-backed. Note wide tertial crescent and wide trailing edge
(skirt) to the secondaries, wider than on Great Black-backed or
Lesser Black-backed. Eyes were pale with dark feathering around the
eye. Legs were bright pink. The bill has a black mark near the tip,
which suggests a young adult. When it raised its wings several times
and flew it showed the diagnostic string of pearls. |
