3. Power of Flight “ birds occupy a greater range of habitats than any other class of organism, plant or animal”

4. The Power of Flight Birds-- “The most successful terrestrial vertebrates on earth”

5. Birds AKA-The Great Flying Machines

6. Adaptations for Flying Skeletal system (hollow bones, thin skull) Integument -- Feathers Respiratory System -- Air sacs “supercharged” lungs Excretory System -- no urinary bladder Reproduction -- no live young Digestive System -- gizzard eliminates the need for jaws

7. Skeletal System Hollow bones-light but strong! Thin skull

8. Skeletal System

9. Feathers Contour feathers -- used for flight –“networked design” Down feathers--used for warmth

10. Respiratory Systems Air sacs provide air movement through lungs

11. Air Sacs

13. Circulatory System 4 Chambered Heart Large heart size compared to body size (40 to 100% larger than mammals the same size) Rapid heartbeat-- hummingbirds = 1000 beats/ minute

14. Hummingbirds 15-80 wing flaps in 1 second Courtship wind flaps go up to 200/ second (depending on species) 2,500-12,000 times per minute

15. 4 Chambered Heart

16. Bird Blood Circulation

17. Digestive System Gizzard removes the need for jaw bones Rapid digestive system for extremely high energy needs

18. Reproductive System No live young Do not store eggs

19. Excretory System No urinary bladder

20. Adaptations for Flying Summary Skeletal system (hollow bones, thin skull) Integument -- Feathers Respiratory System -- Air sacs “supercharged” lungs Excretory System -- no urinary bladder Reproduction -- no live young Digestive System -- gizzard eliminates the need for jaws Circulatory system – large heart, rapid beat..
