Habitat
They can be found in a variety of habitats such as deciduous, mixed woodlands, tidal marshes, arctic grasslands, desert scrub, pinyon pine forests, aspen parklands, prairie shelterbelts, Pacific rain forest, chaparral, agricultural fields, overgrown pastures, freshwater marsh and lake edges, forest edges, and suburbs. They build their nests in grasses or weeds where they are hidden, and the nests are usually near water. The nests are built out of grasses, weeds, and bark and then lined with grass, roots, or animal hair.
They eat mostly fruit and seeds such as buckwheat, ragweed, clover, sunflower, wheat, rice, blackberries, blueberries, strawberries, raspberries, mulberries, and wild cherries. They also eat some insects such as weevils, leaf beetles, ground beetles, caterpillars, dragonflies, grasshoppers, midges, craneflies, spiders, snails, and earthworms. Their dietary sustenance varies greatly with what’s available to them.
