25
parts of a feather
shaft: central attachment part, attaches to skin calamus: proximal shaft, no vanes attached rachis: distal shaft, vanes attached vane: broad part of a feather, has barbules and hooklets keratin: substance feathers are made of pin feathers: visible when molting
26
pterylae
feather tracts: parts of skin that feathers attach to
27

34
pigment-based color
most common, from pigment molecules in feathers, either melanins (black/gray/brown) or carotenoids (yellow/pink, most from diet)
35
structural color
not based on pigment, color caused by microstructure of feathers, changes when hit by light
36
there are no ___ colored birds
blue (it's all structural coloring with reflecting blue light, no pgiment!)
37
order procellariiformes
pelagic species, come to land to breed, called tubenoses, contains albatrosses/petrels and shearwaters/storm petrels
38
"tubenoses" comes from
a tube on the beak, connecting nostrils to an efficient salt gland, allowing birds to drink salt water
39
procellariiformes threats

45
young birds often do not replace ____ during their first pre-basic molt
flight feathers
46
male duck molting
one molt in late summer, quick molt back to bright in late fall, molt all wing feathers together
47
breast muscles
pectorals: 15% weight supracoracoideus: variable, often 6%, up to 11.5% in hummers can add to 25% of weight
48
keel
protrusion on the breastbone that attaches supracoracoideus, a lack of this means the bird likely was not capable of flight
49

54
arboreal hypothesis
tree-living birds glided between trunks, consistent with thecodont origin
55
cursorial hypothesis
ground-living birds hopped and jumped after prey, consistent with theropod origin
56
wing-assisted incline running hypothesis
newest idea from a study in patridges, noticed young flapped wings while running, thought was to decrease weight but noticed that flapping made birds heavier, so new idea was more traction
57
why is archaeopteryx not valuable for information on the early evolution of flight?
it has asymmetrical vanes, showing it is already advanced
58
wing loading
ratio of body mass to wing area smaller number = gliding larger number = better for takeoff, no long distances

variation can occur in wing shape even within species, like with the ____
rufous hummingbird
60
wing slots
gaps between primaries
61
non-flying birds...
live where flying is dangerous, flight is not necessary, need wings for other purpose

accipitriformes and falconiformes conservation issues
used to be hunted as vermin, endangered species include snail kite and California condor, recovered species include peregrine falcon and bald eagle
79
factors affecting clutch size in variable species
time of season (earlier bigger), first clutches larger vs smaller replacement, older females bigger clutches, females in better condition have bigger clutches
80
indeterminate layers
lay enough eggs to get to a particular clutch size, even if some are lost
81
food limitation hypothesis
David Lack: average clutch size is the maximum number of nestings that parents can feed and nourish
82
