Meaning
A medium-sized North American migratory songbird of the thrush family, known for its olive-brown upperparts, spotted breast, and distinctive upward-spiraling, flute-like song.

Linguistics
Semantic Notes
The term is a proper noun (a species name) and is always capitalised ('Swainson's'). It refers exclusively to this one species and is not a general category like 'thrush'.
Dialectal Variation
British vs American Usage
Differences
In the UK, it is known only as a rare vagrant or a species from field guides, leading to higher recognition among dedicated birders. In North America (its native range), it is a well-known summer migrant.
Connotations
UK: An exotic rarity from field guides. US/Canada: A familiar, evocative sound of northern and western forests.
Frequency
The word is used frequently in North American birding contexts but is virtually absent from everyday British English conversation.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation like 'дрозд Свенсона'. Use the established transliteration 'дрозд Свенсона' (drozd Svensona) or the descriptive 'оливковый дрозд' (olivkovyy drozd).
- Do not treat 'Swainson's' as a regular possessive ('belonging to Swainson'); it's a fixed eponym.
Common Mistakes
- Misspelling as 'Swainsons' (missing apostrophe) or 'Swainson' (missing 's').
- Incorrect capitalisation (e.g., 'swainson's thrush').
- Confusing it with the very similar Gray-cheeked Thrush (Catharus minimus).

Frequently Asked Questions
The correct form is 'Swainson's Thrush' with an apostrophe + s, as it is named after William Swainson.
In North America, look in dense, moist coniferous or mixed forests during the summer breeding season. During migration, they can be found in woodlands and thickets.
It is pronounced 'SWAYN-suhn', with the stress on the first syllable.
A key difference is the song and the colour of the tail. The Swainson's thrush has an olive-brown tail and a song that spirals upward. The Hermit Thrush has a reddish tail and a song that begins with a clear, sustained introductory note.
