New Jersey State Bird
Eastern Goldfinch (common name)  Carduelis tristis (scientific name) Overview The brightly colored eastern goldfinch is a popular sight at backyard feeders. The male is vibrant yellow in the summer and turns an olive green color during the winter. The female is yellow-brown in color, turning duller during the winter. Both sexes have a beak that is pink for most of the year and turns orange in the spring. The eastern goldfinch was declared the official state bird of Iowa in 1933 and New Jersey in 1935. It forages in groups for seeds in shrubs and on the ground and will occasionally also eat insects. The bird’s small, conical beak allows the extraction of seeds from thistles, sunflowers, and other seed-bearing plants. The song is a combination of high-pitched twitters, warbling songs, and distinctive call notes. Goldfinches mate for life and raise one or two broods per year. The goldfinch feeds insects to its young.
