Birds of the St. Lawrence:
seasonal status

Two thirds of the species recorded along the St. Lawrence breed in Quebec.

Seasonal status of the 399 species

In addition, two thirds of the St. Lawrence avifauna are migrants that pass through Quebec during migration. Most of these migratory species breed in Quebec; only 24 species, all aquatic birds, are strictly transients and only pass through Quebec to reach their breeding grounds.

Transient migratory species (n = 24): frequented biomes for breeding
and natural provinces where species were observed

Furthermore, 39 species, or a tenth of the St. Lawrence's avifauna, are year-round residents in Quebec, 16 of which are sedentary breeders (and move very little during their lifetime).

One fourth of species are classified as accidental, meaning that their presence along the St. Lawrence is unexpected, since the St. Lawrence does not make up part of their usual range.
