Varied Thrush Ixoreus naevius
STANFORD LOCATIONS: Fairly rare to uncommon resident from fall through spring. Occurs in a number of areas on campus, usually in more heavily vegetated areas than those used by the similar American Robin, although it is often found in flocks of robins. A few can be found near the Mausoleum in winter.
