Do birds have teeth? 5 species with tooth-like features

While modern birds lack enamel teeth, some species exhibit tooth-like features. Geese use serrated ridges called tomia to tear grass, while penguins possess backward-facing papillae to secure slippery fish. Tooth-billed bowerbirds have serrated beaks for shearing leaves, and toucans sport saw-like serrations on their large bills. These adaptations echo their dinosaur ancestors, showcasing nature’s ingenuity in adapting feeding mechanisms.
