The American goldfinch male is well known, with its bright yellow body contrasting with black wings and a black cap. It is one of the common songbirds found in dunes. They are one of the latest nesting birds, typically nesting in July and August. Goldfinches feed primarily on seeds but feed insects to their young. They will often be seen feeding on newly ripened thistle heads, or in winter may be seen feeding on seeds in weedy areas. The goldfinch is one of the most common birds at winter feeding stations in Michigan.
