Ornithology (Birds) Part 2 Flashcards
What is included in a physical exam?
- History
- Weight
CHECK: - Eyes and ears
- Cere and Nares
- Skin and feathers
- Vent/cloaca
- Joints
- HR: 100-300+ bpm
- Respiration: 20-60+ bpm
Temperature: 38-42.5 C
What to look out for when weighing birds?
- Hide illness and weight loss
May not necessarily appear thin
Will fluff its feathers in order to keep warm - Will pretend to be healthy if conscious of being observed by predator (human)
How to weigh birds?
- Feel the keel (sternum): Normally well padded by pectoral muscles
- Use a digital scale - “tare” the towel or box
What to consider when trimming a beak?
- Overgrowth prevents birds from eating properly
- Hook should be trimmed with guillotine nail clippers
- Dremel = great for shaping; also cauterizes
- Hemorrhage; hemostatic compound should be readily available
- Mouth should close comfortably
What tools are needed for nail clipping?
- Dremel
- Scissor trimmer
- File
How to deal with hemorrhage from a nail clipping?
- Hemostatic compound should be readily available
- Apply pressure proximal to the nail to serve as a temporary tourniquet (device to stop the flow of blood)
Why are overgrown nails a problem to caged birds?
- Make it difficult to grasp the perch properly
- Long claws can catch and cause a bird to panic, thus injuring itself
Why can’t you use sandpaper on perches?
- Irritates the feet and predisposes them to infection
-Bumble foot (pododermatitis)
Things to consider during wing clipping.
- Prevents the bird from flying (safety and training)
- Clip the primary feathers but leave the two outermost primaries uncut - can be very irritating
- CAUTION: Watch for blood feathers
- Birds may become withdrawn temporarily
What is a blood feather?
- New feather protected by a sheath of keratin
- It is nourished from its follicle by a blood vessel
- Will hemorrhage if cut
How do you pull a blood feather?
- Use pliers or hemostats
- Grasp at base closest to skin
- Pull quickly
- Apply pressure/coagulant powder
- Clean with hydrogen peroxide
- Let bird rest in a dark, warm, quiet area
When do blood feathers come in?
When bird is young
How do you remove tight bands from a bird?
- Snip plastic bands with scissors or scissor style nail clippers
- Open metal bands that are pinched together
- Use a pin cutter on other metal bands
- CAUTION: Avoid twisting the bird’s leg in the process
Do you remove a wild bird’s band?
DO NOT remove!
- Report bird and band number to MNR
When should a band never be put on a bird?
- When they are still growing (some birds can reach maturity in 3-4 weeks)
How do you care for a sick bird?
- Isolation - A quiet, warm area
- 25-30 C range to prevent hypothermia
- Fresh food and water
- Hydration - Honey water, sugar water, or orange juice may provide a boost for birds that are sick
- Proper housing and hygiene
- Monitor number of birds - Too many will increase stress levels and suppress the bird’s immune system
What to consider for a critically ill bird?
- Stabilization of the bird is essential
- Evaluate the hydration status and condition
- Fluid therapy and/or nutritional support may be necessary before other Tx or Dx
In fluid therapy, what are the water requirements?
50 mL/kg/day
Water increases in what diseases?
- Kidney disease
- Respiratory disease
- GI infections
- Ulcerative skin lesions
All fluids must be warmer to what temperature?
25-30 C
What percentage of body weight can be given SQ?
5-10% of BWT
Are fluids better tolerated SQ or IV?
Subcutaneous
