1.Describe the difference between warm-blooded and coldblooded animals.
Endothermic: “warm-blooded” animal regulates its body temperature internally
Ectothermic: “cold-blooded” the environment regulates the animal’s body temperature
2. Know general characteristics of birds.
Have feathers
Have wings
Lay eggs
Warm-blooded
Vertebrates
4-chambered heart
3. List the functions of each type of beak and talon of a bird.
Beak type and talon type are associated with where the animal lives and how it gathers its food.
Waterbirds: Large bill for scooping food from water, webbed feet for movement through water Example: Duck
Birds of Prey: Sharp bill to rip flesh; sharp talons to grab prey and rip flesh Example: Hawk
Nut-eaters: Stout beak for extra leverage to break nuts; talons good for gripping branches Example: Bluejay
4. Know the characteristics that make flight possible for birds.
Light weight bodies
Light weight bones—crisscrossed for strength
Shape of wings aerodynamic and provide opportunities for lift
Blood circulation allows muscles continual supply of oxygen
5. Know the general characteristics of mammals.
Warm-blooded; Four chambered heart, hair on body, produce milk for young, most give birth to live young, vertebrates

6. Be able to list the three major groups of mammals, provide characteristics of each group, and give examples of each.
Marcupials: immature young, mature in mother’s pouch Ex: kangaroo, opossum
Monotremes: young hatch from eggs; milk lapped from skin
Ex: duckbilled platypus
Placentals: young mature inside mother’s uterus; attached to placenta by umbilical cord; Ex: cat, dog, people
7. Know the types and functions of the teeth of mammals.
Canines: tear
Incisors: bite
Pre-molars: grind
Molars: grind
8. Vocabulary: Bird,
Contour Feather: Flight; Coloration
Down Feather: Insulation
Insulator: Helps body retain heat
Crop: Organ of bird’s digestive system: Stores food for bird
Gizzard: Organ of bird’s digestive system: Grinds food
Lift: Upward push caused by air pressure differences; aids in flight
Mammal: warm-blooded vertebrate that has hair and produces milk for young
Premolar: grinds food
Diaphragm: muscle below the ribcage that aids the lungs in expelling and filling
Incisors: teeth for biting and cutting
Molars: teeth for grinding
Mammary Gland: produces milk
Canines: teeth used for tearing
Monotreme: group of mammals that lay eggs
Marsupial: group of mammal with a pouch
Gestation Period: period of time between fertilization and birth
Placental Mammal: group of mammals that young develops inside the mother attached to placenta
Placenta: nutrient rich layer within the uterus; attached to developing young with umbilical cord
