Habits and Reproduction:
- Mid May returns from wintering grounds in Central America and the north coast of South America.
- Nest on or near ground usually in a grass, fern, or weed clump or at the base of shrubs, such as alders.
- 4-5 eggs, one brood per year but will re-nest if eggs are lost.
- Nests in loose colonies of 2-6 pairs.
- Stops singing usually by mid June when it is feeding their young.
- Feeds on insects, such as caterpillars and spiders usually in tree tops with some feeding in lower shrubs.
- Early succession forest or shrub habitat, such as alder thickets.
- Brown-headed Cowbirds lay their eggs in golden-winged nests and the young cowbirds out compete the young warblers (brood parasitism).
- Cross breeding with Blue-winged Warblers.
- Loss of winter habitat.
- If you’re a coffee drinker, try to buy shade grown, preferably organic coffee. You’ll help protect over wintering habitat for many of our song birds.
