Power of Flight “ birds occupy a greater range of habitats than
any other class of organism, plant or animal”
The Power of Flight
• Birds-- “The most successful terrestrial vertebrates on earth”
Birds AKA-The Great Flying Machines
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
Skeletal System
• Hollow bones-light but strong!
• Thin skull
Skeletal System
Feathers
• Contour feathers --used for flight– “networked design”
• Down feathers--used for warmth
Respiratory Systems
• Air sacs provide air movement through lungs
Air Sacs
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
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
4 Chambered Heart
Bird Blood Circulation
Digestive System
• Gizzard removes the need for jaw bones
• Rapid digestive system for extremely high energy needs
Reproductive System
• No live young• Do not store eggs
Excretory System
• No urinary bladder
Adaptations for FlyingSummary
• 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..
Classification • Only members of the bird class have feathers
