Attract American Robins to your backyard with sunflower seeds, suet and peanut hearts, fruit, and mealworms. Platform feeders are best or food scattered on the ground. Also, try planting some native plants that produce berries, such as juniper, sumac, hawthorn, and dogwood.

2. Song Sparrow

Song Sparrows are frequently spotted in Oregon all year. They appear in 37% of summer and 41% of winter checklists.

California Towhees are only found in the coastal chaparral scrub areas of California, Oregon, and Baja California. They will also visit backyards, sit on fenceposts, and chase their reflections in car mirrors or windows.

California Towhees’ diets are mostly seeds from grasses and herbs, but they also eat berries such as elderberry, coffeeberry, and acorns.

Nests of California Towhees are pretty low down in shrubs or small trees and are made from twigs and grass woven together. The inside of the nest is lined with softer material, such as animal hair and soft fluffy seeds.

Attract Califonia Towhees to your yard with millet on-ground feeders and plant native berry plants.

Swamp Sparrows are located more in the east. They breed in Canada, northeastern US states, and North Central US states before migrating to eastern and southern US states and Mexico.

As the name would suggest, Swamp Sparrows are found in wetlands, swamps, bogs, and coastal marshes. They feed on seeds and fruit, especially in winter, and more insects in spring.

Nests of Swamp Sparrows are usually hidden in vegetation on or close to the ground and made from twigs, leaves, and cattails. The nest is lined with grass and other plant material.

Swamp Sparrows do not visit backyards except in migration to yards with lots of vegetation and water.

You can find American Tree Sparrows foraging in small flocks in weedy fields and under bird feeders.

Nests of American Tree Sparrows’ are usually on or near to the ground and are made of twigs, grass, and moss. They lay around five eggs, and these take just under two weeks to hatch and just over a week for the young to fledge.

Attract American Tree Sparrows to your backyard platform feeders with black oil sunflower seeds, nyjer, cracked corn, and millet. They also feed on seeds dropped on the ground from tube feeders.

30. Northern Waterthrush

Northern Waterthrushes are not often spotted in Oregon but there have been occasional sightings all year.

Northern Waterthrushes are large, thrush-like birds. Males and females both bear similar traits. They both have brown heads with thick, white eyebrows, dark brown backs, and white bellies with dark, heavy streaking from their throats all the way to their rumps.

Northern Waterthrushes breed in Canada, Alaska, and northeastern US states before migrating to Mexico, Central and South America, and the Caribbean. Some may remain all year in Central and South America.

You can find Northern Waterthrushes in dark, woody swamps, thickets, and bogs. If there is any still or sluggish water in the forests, you’ll probably find a Northern Waterthrush around it. In winter, in the tropics, you will usually find them among mangroves. 

The Northern Waterthrushes are aquatic and terrestrial foragers. With their long legs, they can walk on shallow water in search of water beetles, mosquitoes, slugs, crustaceans, snails, and sometimes, small fish. They also eat caterpillars, moths, and ants, which they find under leaves. 

Nests of Northern Waterthrushes are usually located in hollows or crevices near water. They can be in a moss-covered stump or under a jutting bank, but the nests are usually hidden among ferns.

31. Rose-breasted Grosbeak – Female

Rose-breasted Grosbeaks are considered a rare species in Oregon, but you might spot some during migration.

You can find Rose-breasted Grosbeaks in forests, parks, and backyards foraging for insects, berries, and seeds.

Nests of Rose-breasted Grosbeaks are placed in the branches of a low tree. They are made of loosely-formed twigs, grass, and plants. There are about five eggs that take two weeks to hatch. After that, both parents take turns incubating the eggs.
