On Sunday June 10, 2012 Mike Robinson, the Lester Pearson College Ecoguardian at Race Rocks, reported in the Race Rocks log on Caspian Terns and provided this picture:
He comments:
” 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.”
