Mont-Saint-Hilaire Migratory Bird Sanctuary

The Mount Saint-Hilaire Migratory Bird Sanctuary is located east of Montreal island, in Québec. It preserves quality habitat for many song birds and birds of prey, which live here year round.

Importance of the sanctuary: migratory birds and other wildlife

The Mount Saint-Hilaire Migratory Bird Sanctuary, located in Montérégie, near the city of Mont-Saint-Hilaire, Quebec, was established in 1960 to protect the many birds that nest in this area.

Approximately 80 species of birds are thought to nest within the sanctuary’s boundaries, many of which likely spend the winter there as well. Among the wealth of species to be spotted are the belted kingfisher, eastern wood-pewee, least flycatcher, eastern phoebe, great crested flycatcher, eastern kingbird, house wren, winter wren, eastern bluebird, cedar waxwing and a variety of vireos, warblers and sparrows. Breeding raptors can also be observed in the Mont Saint-Hilaire region including:

Canada geese and several other species of waterfowl also put in an appearance and are known to gather by the hundreds at Hertel Lake during the fall migration.

Did you know?

The eastern kingbird owes its name to its aggressive nature. Durant nesting periods, it adopts an aggressive approach, even towards much bigger birds. It sometimes manages to land on the back of an intruder in order to more easily strike them in the head with its beak.


Mont Saint-Hilaire, rising up to 400 metres above the Richelieu River, is an imposing feature in the landscape of this 985-hectare sanctuary. Part of this sanctuary’s charm is due to the remnants of old growth forests (completely untouched by humans) that are still standing tall today. This, combined with the 540 varieties of higher plant species, some of which are found nowhere else in the vicinity, and the great diversity of animal species make this site unique in the area.

While most of the sanctuary is covered in trees, the species to be found vary by location and the wetness of the soil. The summits and steep slopes are dominated by sugar maples, oak trees and pine thickets while in the lower, wetter areas the trees are mostly sugar maple, American beech, yellow birch and American basswood. Along the streams that run through the sanctuary as well as around Hertel Lake the trees are mostly ash, red maple, yellow birch and eastern hemlock. Other softwood trees, including red pine, eastern white cedar and, occasionally, white spruce, can sometimes be spotted mixed in with deciduous species throughout the sanctuary.
