✔✔environmental causes for feather picking - ✔✔dry air, allergens, new stimuli
✔✔medical feather picking - ✔✔lead/zinc poisoning, obesity, vitamin deficiency, skin
infection
✔✔self-inflicted vs. mate-inflicted feather picking - ✔✔self: feathers picked on chest and
body by head and neck are fine
feathers from head/neck are plucked
, ✔✔DNA sexing & its advantages and disadvantages - ✔✔a genetic analysis is
performed using a blood sample to detect the presence of a sex-specific gene
- advantages: non-invasive and cheap
- disadvantages: only the sex of the bird is determined, and no assessment of the actual
reproductive capability of the bird is made.
✔✔Laparoscopic Surgery Sexing and its advantages & disadvantages - ✔✔a small
incision is made so a laparoscope can be inserted into the body cavity on the left side of
the bird to determine if an ovary or testes is present.
- advantages: an assessment of the bird's reproductive maturity is made, anatomical
structural defects in the reproductive tract may be detected
- disadvantages: surgical method is costly, risky
✔✔world-wide distribution of raptors - ✔✔300 species throughout the world
✔✔how many species of raptors are extinct? - ✔✔2; Guadalupe Caracara and Reunion
Kestrel
✔✔raptor diversity in body size and prey consumed - ✔✔- California Condor having a
wingspan of nearly 10 feet and weighing over 20 pounds, while Sharp-shinned Hawk

- Prey on animals of various sizes, from coyotes to grasshoppers
✔✔reverse sexual dimorphism, and its importance in ensuring food for young -
✔✔Females are larger and therefore can hunt different prey, so the baby can get a
more diverse food supply. Reduces competition.
✔✔accipiter vs buteos - ✔✔accipiter: forest hawks, have short, rounded wings
convenient for dash and grab hunting style. Vary in size.
buteos: large, wide-winged, short-tailed hawks that prefer forests with open areas for
soaring
✔✔eagles are large ________. - ✔✔hawks
✔✔the importance of vultures in the ecosystem and preventing disease - ✔✔Because
vultures feed on dead animal carcases, they help prevent the spread of disease. they
specialize in eating bones and dead animals that may have been diseased. "Nature's
Garbage Man"
✔✔diclofenac & the Asian vulture crisis - ✔✔3 vulture species fell by more than 95
percent, became classified as critically endangered. decline due to secondary exposure
to diclofenac, an anti-inflammatory drug given to cattle, a main source of food for
vultures.
Because vultures died: carrion increased, rats an dog populations increased --> rabies
outbreak
