Rhinocryptidae, or tapaculos, are small, ground-dwelling birds found primarily in South America. They are known for their secretive nature and preference for dense undergrowth, making them difficult to observe. Their plumage is typically subdued, often in shades of brown and gray, providing camouflage in their forest habitats. Tapaculos are primarily insectivorous, foraging for insects and other small invertebrates on the ground. They are known for their explosive songs and calls, often used for territorial defense.
