The American Goldfinch is a small songbird native to North America, known for its vibrant yellow plumage in males during the breeding season. They have a distinctive black cap on their heads and white wing bars. Females are more subdued in color, typically displaying a brownish-yellow hue. These birds are often found in open fields, gardens, and along roadsides. American Goldfinches primarily feed on seeds, particularly those from sunflowers and thistles. They are social birds, often seen in flocks, and are known for their cheerful, twittering songs. Their nesting season occurs later in the summer, allowing them to take advantage of abundant seed supplies.
