Swainson’s Thrush Motus update

The Swainson’s Thrush (Catharus ustulatus) makes an excellent species for studying migration. Its impressive migration, matching pace with an extreme ultrarunner, takes it to South America and back annually. Where receiving stations are present, the Motus network (www.motus.org) maps the several thousand mile treks of these long-distance migrants. This report highlights the journeys of many Bitterroot birds over to the central flyway of the U.S. and as far south as Colombia, South America.
