Dendrocolaptinae is a subfamily of birds within the family Furnariidae, commonly known as woodcreepers. These birds are primarily found in the forests of Central and South America. They are characterized by their long, slender bodies, strong legs, and curved bills, which help them forage for insects and other invertebrates on tree trunks and branches. Woodcreepers are known for their unique climbing abilities, using their stiff tail feathers for support as they move vertically up trees. They have a distinctive vocalization, often producing melodious calls that can be heard in their forest habitats. Their ecological role includes controlling insect populations and contributing to forest dynamics.
