Tourist Diane Meilleur on a canoe trip in La Mauricie national park. Every summer, thousands of visitors flock to the lakes in La Mauricie national park to go kayaking, canoeing and fishing, bringing them into contact with the breeding loons (Gavia immer). The presence of the common loon on the lakes makes canoe trips more enjoyable. la Mauricie national park. Quebec. Canada

Juvenile common loon (Gavia immer) taking off. Juvenile loons are on their own after about 12 weeks. The parents head off on migration in the fall, leaving juveniles to gather into flocks on northern lakes and make their own journey south a few weeks later. Once the juveniles reach coastal waters on the ocean, they stay there for the next two years. In the third year, young loons return north, although they may not breed for several more years (on average they are six years old when they start breeding). La Mauricie national park. Quebec. Canada

Common loon (Gavia immer) feeding a three-month-old chick with a small fish. Adults are powerful divers that catch small fish in fast underwater chases. Biologists estimate that loon parents and their 2 chicks can eat about a half-ton of fish over a 15-week period. La Mauricie national park. Quebec. Canada

Common loon (Gavia immer) catching a small fish to feed a chick. Adults are powerful divers that catch small fish in fast underwater chases. They mainly feed on fish, but will also take crayfish, shrimp, and other crustaceans; frogs; insect larvae; mollusks; and aquatic plants. Loons usually swallow their prey underwater, but will bring larger food items to the surface to feed the chicks. La Mauricie national park. Quebec. Canada

A common loon is released after biologists have taken blood samples for mercury analysis and have banded the bird. The banding of loons provides a reliable field method to re-observe individuals over many years and to track whether or not they are returning to their breeding lakes each summer. Additionally, banded loons are occasionally encountered alive or deceased on their non-breeding areas. A recovered banded loon provides important information on that individual’s or possibly, an entire breeding population’s wintering range. La Mauricie national park. Quebec. Canada

A few years ago, I and wildlife biologist Denis Masse, today retired, went on one of the 150 lakes of La Mauricie national park. Mr Masse worked for the park's conservation service and wanted to verify whether a pair of common loons has used one of the nesting rafts built here. These rafts are never submerged by water and they allow the loons to carry out the incubation of the eggs even if the water level rises on the lake during heavy rains.
