Catharus ustulatus, commonly known as the Swainson's Thrush, is a medium-sized songbird with a brownish-olive upper body, pale buffy underparts, and a white eye-ring. It has a long, slightly curved bill and a long tail. It is found in deciduous and coniferous forests, as well as in shrublands and grasslands. Its lifespan is typically 2-3 years, and its current population is estimated to be between 6 and 7 million individuals.
Name Origin: The scientific name of the Catharus ustulatus, also known as the Swainson's Thrush, is derived from the Greek word "katharos" meaning "pure" and the Latin word "ustulatus" meaning "burnt". This is likely a reference to the bird's distinctive plumage, which is a mix of dark brown and pale gray.
