Mike Robinson, the Lester Pearson College Ecoguardian at Race Rocks Ecological Reserve, reported in the Race Rocks log on Caspian Terns and provided this picture.
This is the first image taken of this species at Race Rocks June 10, 2012.

Mike  commented :” I have noticed several (2-6) Caspian Terns (Hydroprogne caspia) in the area for a month or so. They have proven very challenging to photograph but I got a couple good shots this afternoon. It is the world’s largest tern with a length of 48–56 cm, a wingspan of 127–140 cm. The global population is about 50,000 pairs. They have a distinguishing croak that sounds a bit like a Great Blue Heron.”
