Word for cleaning feathers? preen

3 systems united in cloaca Digestive, reproduction, excretory

Brood patch is what? Bare skin to keep eggs warm

Name of bird/reptile found in Germany? Archopteryx lithographacus

Central portion of a feather (vein) rachis

How many chambers are in the heart? four

Pterodactyl means? Wing finger

Why was limestone in demand in the 1700’s printing

Special feature of respiratory system Air sacs

Cow birds and cuckoos have odd rearing practice Brood parasitism

Three functions of a feather Flight, mate, and insulate

Two major lobes of the brain? Optic and cerebellum

Why do birds change feathers and what is it called? Molt Mate migrate

2 skeletal features that aid in flight? Hollow, fused bones

How are birds classified? Anatomy, DNA, song

Protobird has reptile and bird features such as Teeth, feathers, fine boned skeleton, and scales

Why would birds have a broader range then reptiles? Endothermic and feather

Contrast precocial and altricial? Number of eggs Nests on ground Behavior at birth

Describe the two theories of bird origin Cousins of dinosaurs because of common ancestor OR descendent of dinosaurs

Factors that influence migration Food, season, mating

Resources that help in navigation Stars, magnets in head, visuals cues

List organs in the digestive system Mouth, esophagus, crop, proventriculus, gizzard, intestine

Compare and contrast birds and reptiles Type of egg shell Ecto vs. endothermic Feathers scales incubation of eggs in nest or not
