baby bird, often called a hatchling or chick, is typically small, delicate, and covered in soft, sparse down feathers, or sometimes completely featherless depending on the species. Its body is usually plump with a proportionally large head. Baby birds often have large, round eyes that may appear closed or only partially open if they are newly hatched.
Their beaks are soft and sometimes disproportionately large, with a bright-colored gape (the fleshy part at the base of the beak) that helps parents target the mouth during feeding. Their wings and legs may seem underdeveloped or fragile. Baby birds tend to make soft, high-pitched chirping sounds, especially when hungry or seeking attention from their parents.
