- Size: Length 20–22 cm, weight 53–79 g.
- Nest: In trees at a height of 0–12 m (most commonly 1–2 m). Bowl-shaped, made of twigs, moss, lichen and dry leaves, lined smoothly with splinters of decaying wood glued together with saliva.
- Breeding: Lays 2–6 eggs in April-May. Only females incubate, for 10–18 days. Fledglings remain in nest for 12–16 days.
- Distribution: Nests in all kinds of forest throughout Finland, but population becomes progressively sparser further north. Finnish breeding population estimated at 800,000–1,400,000 pairs.
- Migration: Nocturnal. Leaves Finland September–October, returning April–May. Winters in Mediterranean countries.

Song Thrushes look like smaller Mistle Thrushes. Their backs are a uniform olive brown, and their paler underparts are dotted with dark arrowhead-shaped speckles. When sitting, their posture is more hunched than that of the longer-necked Mistle Thrush. Song Thrushes can be distinguished from the similar-sized Redwing by the lack of a visible white eye stripe and the yellowish brown colouring visible on their flanks, instead of red. Their legs are pinkish. Their beaks are dark brown, with a yellowish base to the lower mandible. Their irises are dark brown.
