Q

What is pinioning?

A

The permanent removal of part of the wing when the bird is 3-4 days old when the wing is cartilaginous. If the bird is older, surgery is required (by a vet!). Anaesthesia is always required and pinioning is only for the bird’s best interest.

48
Why should we provide supplements to birds?
Calcium and Phosphorous (Ca, P) are important minerals in the diet and need to be taken into the body through the diet at the correct ratios. The body needs phosphorus to absorb calcium through the intestines. If there is more phosphorus than calcium then phosphorus starts to take calcium from the animal’s bones resulting in metabolic bone disease.
49
What ratio of Ca:P should a bird have
2:1
50
Timed feeders:

82
Define homologous
When we have similar structure in different organisms
83
How do a bird’s phalanges differ to a human’s?
Only 3 phalanges as opposed to 5
84
The two main muscles associated with flight are:
Pectoralis: pulls the wing down, extremely large, powerful muscle Supracoracoideus: lifts the wing up, smaller than the pectoralis
85
How does the Supracoracoideus muscle lift the bird’s wing?
The muscle is below the sternum, looping through the clavicle and shoulder and attaching to the humerus, acting as a pulley.
86
What are down feathers for?
Insulation
87
What are contour feathers for?
Protection from the elements, adds shape to the bird, aerodynamics
88
What are the semi plumes for?
Help fill in cavities, keeping the aerodynamic shape, insulation
89
What is a pneumatic bone?
A hollow bone. Helps with shock absorption
90
Sternum/Keel:
The keel part of a bird’s breastbone extends outward from the top of the bone and down the breast area. It acts as an anchor for a bird’s strong wing muscles. It is a feature of strong flying or swimming birds.
91
Fused thoracic vertebrae:
Fairly rigid and helps the bird resist strong forces when flying.
92
Avian Ribs:
Provide leverage for the attached muscles. Prevents the birds chest from collapsing when the large pectoral muscles are contracted. Also helps to expand and contract the chest when breathing.
93
Avian skull:
Aerodynamic when flying
94
Wings:
Strong/durable for flight but no ability to grasp
95
Avian neck:
Elongated. Used as a counter balance. Very flexible in order to reach around the body.
96
Avian legs:
Shock absorbing for landing.
97
Avian tail:
The rudder and break in flight, important for balance.
98
What are the parts of the human digestive system? (In order)
1. Mouth 2. Oesophagus 3. Stomach 4. Duodenum a. Pancreas b. gallbladder c. liver 5. Small intestine 6. Large intestine a. caecum b. colon c. rectum d. anus
99
Crop:
A pouch in the oesophagus - this allows the bird to eat lots of food at once and then digest it slowly later. The bird can throw up this food to take off quicker if a predator is near.
100
Proventriculus:
This is the first ‘stomach’. This is where acid is added to the food.
101
Gizzard (ventriculus):
Very muscular stomach with thick walls: this mechanical organ grinds the food before it enters the small intestine.
102
Cloaca:
Birds only have one exit for the digestive system, urinary system, and reproductive system. This is knows as the cloaca or vent.
103
What are the 4 parts of the excretory system? What are their functions?
1. Kidneys - remove waste and excess fluid 2. Ureters - transports urine to bladder 3. Bladder - holds urine 4. Urethra - excretes urine
104
Birds have kidneys and ureters the same as mammals but lack a ________ and _______. The ureters lead directly to the _______. Ostriches are the exception. Unlike mammals, they excrete ______ _____ instead of urine. ________ is converted to uric acid in the ________. This is then mixed with _______ from the digestive system and exits the body from the ______. This system reduces the amount of _____ that is lost from the body.
Birds have kidneys and ureters the same as mammals but lack a (bladder) and (urethra). The ureters lead directly to the (cloaca). Ostriches are the exception. Unlike mammals, they excrete (uric acid) instead of urine. (Nitrogen) is converted to uric acid in the (kidneys). This is then mixed with (waste) from the digestive system and exits the body from the (cloaca). This system reduces the amount of (water) that is lost from the body.
105
How do birds mate?
After courtship, the male will tread the female whereby their cloacas are rubbed and sperm is transferred. Some species have a phallus-like organ that transmit sperm, these mainly include waterfowl and ratites.
106
Parts of the oviduct: Funnel
The released mature ova enters here
107
Parts of the oviduct: ova
(Basically the yolk). A cluster of ova at various stages of maturity.
108
Parts of the oviduct: magnum
Layers of albumen added here (3 hours)
109
Parts of the oviduct: Isthmus
Protective membranes added here (1 hour)
110
Parts of the oviduct: shell gland/uterus
Shell and bloom added here (20 hours).
111
Parts of the oviduct: Vent
Egg emerges here (1 hour or less)
112
How is an egg formed?
1. Nutrients carried to the ovary from the body 2. Ovary - follicles full with yolk and grow - largest follicle will release the yolk of the egg the hen will lay tomorrow 3. Yolk travels down the infundibulum- fertilisation will occur here 4. Magnum - the yolk is covered in albumin (egg white) 5. Isthmus - shell membrane is formed here 6. Shell gland - water moves into egg to create “egg shape”. The shell is created 7. Vagina - egg turns around (oviposition) 8. Egg comes out of cloaca
113
Breeding triggers:
• length of day • temperature • humidity • food availability • vocalisations • presence of opposite sex • breeding colony • sexual maturity • circadian rhythm cycles • follicle stimulating hormones produced in the pituitary gland stimulate reproductive systems
