Head and beaks of 6 birds.
These models were used to show how birds evolved different shapes of beaks, each adapted to a specific feeding habit.
The short, wide and robust beak of the Hawfinch (Coccothraustes coccothraustes) helps him crack open fruit pits and other seeds.
The long beak of the eurasian curlew (Numenius arquata) helps him probe mud in shallow water to find worms, insects, molluscs, and other invertebrates.
The european bee-eater (Merops apiaster) has a typical insect feeding beak. They catch their prey in flight.
The Common buzzard (buteo buteo) has a powerfull curved beak typical of birds of prey. They feed on a large range of small vertebrates.
The sharp and hydrodynamic beak of the common kingfisher (Alcedo atthis) helps him hunt fishes, diving on them from above.
The Anna's humming bird (Calypte anna) has a specialized beak to feed on flower nectar.
