The Avian Health Exam

Pet owners are accustomed to taking the family dog or cat to the
veterinarian for an annual check-up. It is even more important for a pet bird to have
regular examinations, because birds tend to have very subtle symptoms of disease.
Quarantine
Isolation and quarantine of a new bird is the first and most important thing an owner
should do. In order to protect other birds on the premises, it is advised that all newly
acquired birds be maintained separately for a period of at least six weeks following
purchase. Because many air-borne viruses may be spread from room to room by central air
conditioning or heating systems, an off-premise location is preferred. Quarantine is
essential for all new birds, even those that are believed to be "healthy".
New Bird Examination
The second most valuable step for a new bird owner is to establish a relationship with
an avian veterinarian, preferably one who is a member of the Association Avian
Veterinarians.
An examination of a newly acquired bird within the first three days after purchase is
recommended in order to protect the investment of the owner, to uncover and prevent
possible diseases conditions, and to educate the owner about appropriate bird care.
Even if the new bird checks out "normal", results of diagnostic tests in the
initial patient record provide valuable references for subsequent examinations.
Components of the Exam
History
Your veterinarian is very interested in what you know about the background of your
bird; its age, sex, origin, length of time in the household, diet, and caging. Even if the
bird has been a household pet for a long time, the veterinarian should be advised of any
contact, direct or indirect, with other birds. Examples of indirect contact would be the
owner's buying of bulk seed from open bins in a pet shop that houses birds, or visiting
other aviaries, bird shows, or bird markets.
Physical Evaluation
From an initial, critical observation of the bird in the cage, the veterinarian can
determine general body conformation (obesity, tumors), posture, attitude, and character of
respiration. Although many internal problems may not be evident from a step-by-step,
hands-on examination, an experienced avian veterinarian will be able to note abnormalities
in the feathers, skin, beak, eyes, ears, cere, nares, oral cavity, bones, muscles, abdomen
and vent.
Weight
Once a bird has become an adult, the weight should remain relatively constant. Checking
the weight occasionally, especially at the annual examination, will give valuable
information about your bird's health. A bird's weight should be measured in grams, not
ounces, in order to detect small increments of change.
Testing Procedures
Depending on the bird's history, results of physical examination, species, age, and
general condition, your veterinarian may suggest some of the following diagnostic
techniques that will assist in evaluating your bird's health.
Appraisal of Droppings
The appearance of the droppings, volume, color, and composition, may help the
veterinarian generally assess the bird's health and consider certain disease conditions.
Most birds are nervous in the clinic, so their droppings may be abnormally loose there. A
fecal sample may be examined microscopically to determine the presence of internal
parasites.
Chlamyophila Test
Several screening tests are available for the detection of psittacosis or parrot fever.
This is important as part of the new bird exam or annual check-up because the causative
agent, Chlamyophila psittaci, may be transmitted from birds to humans.
Blood Tests
A blood sample might be taken to determine the amount and distribution of blood cells.
This information may suggest the possibility of certain diseases, and further tests may be
indicated for confirmation. A series of chemistry tests performed on the blood sample may
point to imbalances in biochemical functions and suggest the possibility of organ
dysfunction. Blood parasites may also be detected.
Microbiology
Your avian veterinarian may recommend a culture of the choana (throat), cloaca (vent),
crop, or some other tissue/fluid sample to determine abnormal growth of bacteria or yeast.
At the same time, antibiotic sensitivity discs may be used to determine an appropriate
antibiotic to be used if the bacterial growth requires therapy.
Radiographs
X-rays may be used to assess the internal condition of your bird. The presence of old
or new fractures, the size and relative relationship of internal organs, the presence of
foreign bodies or soft tissue masses such as tumors, and the condition of lungs and air
sacs are often evaluated with radiographs. The use of anesthesia may be necessary to
produce quality X-rays.
Cytology
With the use of special stains, a veterinarian skilled in this procedure can evaluate
smears of tissues or fluids to assist in making a diagnosis.
Virus Screening
Some new tests are currently becoming available to screen birds for certain viruses.
The detection of viruses is especially important for aviary birds. Some viral agents do
not express themselves as clinical disease until the bird is under stress, such as laying
eggs, feeding young, or at weaning.
Annual Check-Ups
Because owners are often unaware of obvious symptoms in the beginning stages of disease
in birds, annual check-ups are advised for early identification and management of
potential disorders. Also, new information of interest to the bird owner is continually
becoming available.
