BigDaddyData.Com: Iowa Eastern Goldfinch

    The Iowa Legislature designated the Eastern Goldfinch as the official state bird in 1933. It was chosen as the state bird because it is commonly found in Iowa and often stays through the winter

    Seeds from dandelions, sunflowers, ragweed, and evening primrose are the main source of food for the Eastern Goldfinch. In late July or early August they build their nests from plant materials and line them with thistledown. The pale blue-white eggs of the Eastern Goldfinch incubate for two weeks and the young birds leave the nest when they are two to three weeks old.

    The top of the male's head is topped with black. The bright yellow body has black wings and tail. The female has a dull olive-yellow body with a brown tail and wings. The male goldfinch acquires the same dull plumage in the winter months.
