The World Wildlife Fund's WildFinder is a nifty little tool to find out about species native to areas all over the earth, with several different ways to explore. It has 284 species for the Vancouver area. As you might expect, it's mostly birds and small mammals, with a couple amphibians and reptiles. I also learned that the scientific name for the American Beaver is Castor canadensis, which in yet another display of my massive geekery I find amusing.
