Species Showcase Yellow warbler
Sweet-sweet-sweet-sweet-I’m-sosweet goes the yellow warbler’s crisp song. True to their name, these peppy birds are almost entirely sunny yellow. Males have soft chestnut streaks on their chests. Though common throughout Lake County, yellow warblers face pressure from brown-headed cowbirds. Cowbirds don’t build nests. Instead, they dodge parenting duties and lay their eggs in the nests of more than 200 other bird species. Surprisingly, most host birds don’t notice. They raise the oversized chicks as their own—but not yellow warblers. When a female spots an unfamiliar egg in her nest, she buries it under a fresh layer of material. Researchers have found some unlucky nests with as many as six layers built atop intruder eggs. 34
