Roughly the size and shape of an American robin, Swainson's thrushes have olive-brown to rust-brown colored upper-parts, and a cream-colored underside with pale brown spots that are clear on the chest and become smudgier further down on the belly. They also have a pale brown ring around the eye, dull pink legs, and a medium-length brown tail. Males and females have similar color patterns.
While it can be hard to tell apart from the hermit thrush and the veery, Swainson’s thrushes can be identified among its close cousins by the buff-colored ring around its eye.
Swainson's thrushes live in dense, thick forests with a mix of leafy trees and conifers. They prefer to be in areas with lots of undergrowth. While migrating, they are often spotted in forests, lake edges and suburban parks.
Their range extends across the United States during migration, stretching from Alaska and western Canada to the Atlantic Ocean, and down into the northern U.S. for the breeding season. Their wintering range extends from Mexico through Central and South America into northern Argentina. One subspecies can be found along the Pacific Coast from southern California to Alaska.
During the breeding season, males reach the nesting grounds a few days ahead of the females, establishing their territory by singing and repelling other males. After choosing a mate, the female will build a cup-shaped nest out of twigs, moss, leaves and grasses. Females lay clutches of 3-4 pale blue eggs colored with brown spots. Incubation lasts about two weeks, and both parents care for the nestlings after hatching. After a steady diet of insects caught by their parents, the young are ready to leave the nest after about two weeks. Swainson’s thrushes will often return to the same site to breed year-over-year.
- Be a smart consumer. Choose products made with sustainable ingredients, such as Smithsonian certified Bird Friendly coffees, which support farmers striving to limit their impact on wildlife and habitat.
- Practice ecotourism by being an advocate for the environment when you’re on vacation. During your travels, support, visit or volunteer with organizations that protect wildlife. Shop smart too! Avoid buying products made from animals, which could support poaching and the illegal wildlife trade.
- Be a responsible cat owner, and keep cats indoors or under restraint when outside. Never release animals that have been kept as pets into the wild.
- Conservation starts with you! Join a citizen science project, such as FrogWatch or Neighborhood Nestwatch, where you can help collect valuable data for scientists. Encourage your friends and family to get involved too.
- Plant native flowers in your garden to help feed resident and migrating pollinators. You'll make your lawn beautiful and help wildlife at the same time!
- Never release balloons. Animals often mistake them for food or become entangled in their strings. Looking for an alternative? Try blowing bubbles instead!
