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)

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.

You can find Evening Grosbeaks in forests and mountain regions. During the winter, they’re often attracted to bird feeders in backyards, most often because it’s an easy food supply.
Evening Grosbeaks naturally feed on flower buds during spring; insect larvae from treetops during the summer; and in the winter, they flock to backyard feeders or feast on seeds, berries, and small fruit.
Evening Grosbeak Song:
Nests of Evening Grosbeaks are usually found up to 100 feet above ground in pine trees. The nests are loosely made, composed of twigs, rootlets, grass, moss, and pine needles. There are usually up to five eggs laid by the female, and she incubates them for two weeks until they hatch.
