Identification and Whereabouts

Slightly larger than smaller birds, approximately the size of a Red-winged Blackbird. Observe the tail colour to differentiate this bird from its close relative, the Hermit Thrush. The Swainson's Thrush has a uniform olive colour on its back that extends to the tail feathers.

During the spring migration, Swainson's Thrushes can be observed in Tadoussac, particularly in May. They are often seen in large numbers, feeding within the bushes and trees along the coast.
