Enormous whales, belugas and seals are found in the St. Lawrence River. These marine mammals are drawn by the abundant food found in these waters, as are the hundreds of thousands birds living in the area. Fish and shellfish are caught as food by humans, though quotas are established to prevent overfishing. Did you know that laws exist to protect endangered animals, plants and habitats? And there are many fun facts to learn about the river!


The St. Lawrence is home to thousands of interesting plants and animals living in perfect harmony. But the slightest upset to this environment can have devastating consequences. For over 20 years, scientists have been studying the flora and fauna of the St. Lawrence in order for us to gain a better understanding of life in and around the river. Sometimes, they found it necessary to sound the alarm. Learn more about the seaway, a thriving habitat.

In early October, eagles, vultures and other birds of prey or eaters of carrion are seen gliding over the sand dunes near Tadoussac in large numbers. These birds have come from the boreal forest and seem to gather in Tadoussac before beginning their long trip south. But why do they stop here? Because the river becomes narrow at this spot, while it is very wide elsewhere along the North Shore. Evidence suggests these birds go their separate ways shortly after leaving Tadoussac and crossing the river to continue their trip south.

Every year, naturalists and biologists set up temporary blinds. They catch a few animals, tag them, then release them into the colourful autumn sky.
