29 Yellow Birds In Delaware:
1. American Goldfinch
American Goldfinches are spotted in Delaware all year, but their numbers increase during the breeding season. They are recorded in 40% of summer checklists and 20% of winter checklists submitted by bird watchers for the state.
American Goldfinches are popular birds, especially due to the males’ bright yellow and black coloring in spring. The females are duller brown, as are males in winter.
- Spinus tristis
- Length: 4.3-5.1 in (11-13 cm)
- Weight: 0.4-0.7 oz (11-20 g)
- Wingspan: 7.5-8.7 in (19-22 cm)
American Goldfinches can be found in most of North America and are usually resident all year. However, those that breed in Canada and the Midwest migrate to southern US States for winter.
You can find American Goldfinches in weedy fields and overgrown areas foraging for sunflower, thistle, and aster plants. They are also common in suburbs, parks, and backyards.
American Goldfinch Song:
Nests of American Goldfinches are usually in shrubs and are made from rootlets and plant material woven together and held firm to the branch with spiders’ webs. They lay up to seven eggs which take up to two weeks to hatch and two or two and a half weeks for the young to leave the nest.
Attract American Goldfinches to your backyard by planting thistles and milkweed. They will visit most bird feeders and prefer sunflower seed and nyjer seed.
Fun Fact: Cowbirds have no luck in getting the American Goldfinch to raise their young as their solely vegetarian diet is no good for cowbird chicks, and they die within a few days.
