Unlike birders, we fish lovers can seldom go to a lake or river and simply “see” a fish. To see one, we usually need to catch it. The question is: can occasional losses from catch-and-release fishing be safely ignored or are they a cause for concern?

Measuring loon productivity is also an excellent indicator of lake health. As top predators, loons are sensitive to damage at lower levels of the food chain. For example, processes that decrease the number of fish in a lake can cause food shortages, especially for young loons. Being a top predator also makes loons more vulnerable to pollutants, like acid rain and mercury.

Eastern kingbirds belong to a group of birds known as the tyrant flycatchers, and the Latin name of this species, Tyrannus tyrannus, reflects their pugnacious nature.

Break out the champagne, it’s time to celebrate! Minister Nixon has rescinded the government’s plan to delist 164 parks from Alberta’s park system. He could hardly have done otherwise.
