Q

diets not reccomended for psittaciformes?

A

o All seed diet

o Animal products

o Minimize table food( depends on owner’s diet)

o Toxic items

21
Q

why should psittaciformed not be fed all seed?

A
  • High fat low nutrient diet
  • Lacks key nutrients such as vitamins (mainly A), minerals, proteins
  • Selective feeders
22
Q

toxic food items for psittaciformes

A
  • Avocado
  • Chocolate
  • Alcohol
  • (plants intoxication are rare in pet birds)
  • Foods containing mycotoxins (poor quality corn and nuts)
  • Salty food
23
Q

is it easy to convert a seed eater to a different diet? how can we try?

A
  • “Seed eaters” may be hard to convert
    o Alternatives to pellets that are healthier than all seed diets
    o Mix pellets with seeds, foraging…
24
Q

baby parrots: when are they weaned? how do we feed?

A

o Most small parrots are
weaned are 1-2 months
o Most medium-large parrots are weaned at 3-4 months
o Need neonate formula
- Fed frequently (6-10 times a day) large
volumes
- Body temperature
- Don’t microwave
- Don’t store prepared food

25
legal requirements for birds of prey?
o CITES permit (depends on source), falconry license, hunting license
26
where can someone source a bird of prey?
o Breeders o Trapped from the wild - Only red-tailed hawks, Cooper’s hawks, sharp-shinned hawks, and merlins - Only juveniles - Need to apply for authorization to MNRF first o Non-releasable birds (with MNRF permit) - Education centres
27
options for housing for birds of prey?
* Kept outside o Tethered (weathered) o In aviaries * Tropical species or migrating species o Inside in winter o With heated perches outside
28
tenets of aviary design for birds of prey?
o Predator proof o Easily cleanable (e.g. pea gravel) o Prevent parasite intermediate hosts (earthworms, cockroaches...) o Variety of perches (often covered with artificial turfs for falconry birds) o Large enough for short flights
29
Falconry equipment and vocabulary
o Mutes=feces o Casts=pellets o Tiercel=male
30
why are Falconers are demanding clients?
o Expect that you know a minimum about raptors and falconry practices o Training is based on conditioning and food motivation (some falconers may “lower” their bird too much) - Trade-off between food motivation and good muscle mass for flying o Keep a close eye on their birds and weight regularly, keep logs o Tendency to treat their birds themselves o Hard to build trust
31
diet for birds of prey
o Whole preys - Quails - Day-old chicks (high in cholesterol) - Rats/mice - Fish (need to add vit tabs) - Pigeons (carrier of several diseases) - Hunted preys for falconry birds (ducks, rabbits)
32
housing for columbiformes
* Kept as pets or in large “pigeon lofts” o “cells” with nesting boxes o Some lofts are open
33
Columbiformes aviary design
oPigeons are messy - Separation from feces and food debris (wire mesh floor) - Good ventilation - Cleaned on regular basis
34
big columbiformes industry and general practices in it
* Pigeon racing is a big industry o Pigeons are released far away (typically males) and return to their cell on their own o Many different types of races o Owners tend to use a variety of supplements and drugs o Seldom go to veterinarians
35
types of pigeons you would most likley see as a vet
* Most likely to see pet pigeons * Some pigeons are farmed for meat
36
Columbiformes diet
oStrict granivorous oSwallow seeds whole oNeed grit in their ventriculus to crush and digest seeds
37
how is the backyard chicken industry changing? how is it different from commercial?
* Rising trend oPets and eggs oDifferent breeds than in the poultry industry (“heritage” breeds)
38
backyard chicken housing
* Kept in a coop oNeeds to be heated and well ventilated oCleanable, changeable substrate oPredator-proof (especially raccoons) - Predator trauma is a common cause of presentation
39
issues with backyeard chickens
* Loaded with diseases o Not vaccinated o Bacterial and viral diseases very common o Impossible to avoid parasite transmission * Challenges with veterinary care o Owners eat eggs o Withdrawal times not determined for most drugs in eggs o Lack of authorization to use drugs on layers o Some drugs are not recommended for use - Chloramphenicol - Cephalosporins - Quinolones - Metronidazole
40
backyard chicken diet
oSpecific pelletized diet (layers, growers...) oEgg-laying chickens needs more nutritious diet and more calcium oOmnivorous, foraging outside
41
how are anseriformes usually kept, and why? what do they absolutely need?
* Pets or ornamental o Frequently “pinioned” * Need water access o Will develop problems without
42
Anseriformes diets, and important consideration
o Waterfowl pellets and plants o Be careful with chicks and high-protein diet
43
Passeriformes: common reasons they are kept
* Companionship or ornamental birds * Show oSinging canaries (males) oGeneral appearance
44
Passeriformes housing
* Typically kept in small cages or aviaries oSome fly in the house and go back to their cage
45
why is photoperiod important for passeriformes
oBreeding and singing
46
Passeriformes diet
oSeed mix oChopped-up vegetables oInsects (dusted with calcium) o“egg food”
47
Baby wild passerine birds are common to find in what human setting? what do they eat, and what issues do they have that we must be attentive to?
o Extremely common in wildlife centres o Most are insectivorous (or insectivorous when chicks) o Susceptible to metabolic bone disease o Need to be kept warm o Hand fed with (will typically beg, q30-60 min): - Moisten kitten pellets (with added calcium) - Dedicated songbird nestling handfeeding formula (e.g. Mazuri) - Home-made formula - Live insects
48
what principles can prevent many avian diseases?
Optimal captive husbandry and diet may prevent many diseases
