Birds that are carnivorous, piscivorous, nectivorous, insectivorous, and filter feeders may have specialized beaks adapted for their specific diets. For example, carnivorous birds may have sharp, hooked beaks for tearing flesh, while piscivorous birds may have long, pointed beaks for catching fish. Nectivorous birds may have long, slender beaks for reaching into flowers for nectar, insectivorous birds may have narrow, pointed beaks for capturing insects, and filter feeders may have wide, flat beaks for straining food from water.
