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
