What is the order for waterfowl?

What is included in the order galliformes?

What are the types of feathers?
tail (retrices)
flight
semiplume
filoplume
bristle
downy
How does an asymmetrical feather allow for flight?
smaller part of vane: smaller surface area —> leading edge
thicker part of vane: greater surface area —> trailing edge
Flight feathers act as an air foil, which means that air rushes faster over the top of the feather (leading edge) than the trailing edge which creates lift
What are the functions of feathers?
flight
thermoregulation
sexual dimorphism
protection
What is the microanatomy of a feather?
barb
barbules
hooklets
What are the flight feather types?
primaries
secondaries
alula
Where do primary feathers attach?
manus
Where do secondary feathers attach?
antebrachium and brachium (trailing edge)
What is the function of the alula?
prevent stalling in flight
Label 1-3
- alula
- primaries
- secondaries
Is this a right or left feather? What kind?
left

How many digits does a bird have on each manus?
3
What is the word for fused vertebrae in the avian?
notarium
What is the synsacrum?
fused hip bones and sacral vertebrae
What is the pygostyle?
fused caudal vertebrae
Label 1-4
- clavicle
- coracoid
- metatarsal
- pygostyle
What are the anatomical features of the avian skull?
fusion of skull bony structures
single occipital condyle
What accounts for the kinetic movement of the beak?

stapes
What bones is the triosseal canal made of in the avian?
scapula
coracoid
furcula
What passes through the triosseal canal?
tendon of the supracoracoideus muscle
Where does the supracoracoideus m. attach? Its function?
proximal tubercle of humerus
upstroke of the wing
The pectoralis m. of the avian is responsible for the ____ of the wing. Where does it attach?
downstroke
