How to Identify

A bit larger than the small birds, about the size of a Red-winged Blackbird. I look at the colour of the tail to distinguish this bird from a close relative the Hermit Thrush. The Swainson's Thrush's olive color of the back is uniform and extends to the tail wings.

Where When to Spot

I saw this bird during spring migration in Tadoussac, May 2018, in large numbers feeding within bushes and trees along the coast.
