The Yellow Warbler is a small, vibrant songbird known for its bright yellow plumage and cheerful melodies. These birds are commonly found in North America, especially near wetlands, rivers, and gardens. Their distinctive song, often described as a sweet "sweet-sweet-sweet, I'm so sweet," makes them a favorite among birdwatchers and nature lovers. During the breeding season, Yellow Warblers build cup-shaped nests in shrubs or trees, where they lay 3 to 5 eggs. They are also known for their unique behavior of feeding on insects and caterpillars, which helps control pest populations in their habitats. Their striking appearance and lively songs make them a delightful sight in the wild.
