Bird Characteristicsendothermic: warm blooded (maintain constant body
temperature by food and feathers)
feathers
air sacs
First 4 chamber heart (prevents mixing of O2 rich and O2 poor
blood)
eggs (hard shell)
“care for young” behavior (feed & protect until young able to fly)
internal fertilization

Adaptation for Flighthollow bones
wings
large chest muscles
feathers (2 types):
contour feathers- steering & flight
down feathers- trap heat & warmth
air sacs- connected to lungs to obtain more oxygen
_______________________________________________
Bird FlightBird’s upward curved wing causes faster moving air above wing (= lower pressure) and slower moving air below wing (= higher pressure). As the bird moves through the air, the high to low pressure results in an upward force called lift. Lift results in flight.

Obtaining FoodBills – tear, strainer
Crop - internal storage tank
Two part stomach:
Part 1: chemical breakdown
Part 2: gizzard- physical breakdown with stones (gastroliths)

Role of Birds in the EnvironmentMost diverse vertebrate group. Their role: pollinators disperse seeds pest predators
Origin of the Birds:Birds are believed to be descended from Archaeopteryx (a reptilian dinosaur with wings and feathers)
