The Red-winged Blackbird male is unmistakable for most Michigan residents. The pure black bird with bright red shoulder patches edged in yellow is hard to miss. The female and juvenile are less obvious. They have heavily streaked under parts and mottled brown upperparts and can look like large sparrows.

During the breeding season, Red-winged Blackbirds eat mostly insects, including dragonflies, damselflies, beetles, butterflies and moths. They often use a feeding technique known as gaping. They expose insects that are hiding under sticks and stones or in the bases of leaves by forcibly spreading open their bills. If no bugs are available in early spring they may initially frequent your feeder. They enjoy suet, nuts, and sunflower seeds.
