Beak Morphology
• Beaks tell us what the bird eats and where it lives.• This helps biologists identify, classify, and track birds• The scientific idea of Form vs. Function:
• Form vs. function: • That a shape and composition of a structure will tell us
what the organism eats, where it lives, and how it lives.
