Health Exam for Birds
By The Association of Avian Veterinarians
Pet owners are accustomed to taking the family
dog or cat to the veterinarian for an annual checkup, but it is
even more important for a pet bird to have regular examinations,
because symptoms of disease in birds tend to be much more
subtle.
Quarantine
Isolation and quarantine of a new bird, even
those that are believed to be "healthy" are the first and most
important things an owner can do. In order to protect other birds
on the premises, it is advised that all newly acquired birds are
maintained separately for a period of at least four weeks, six
would be best, following purchase. Many airborne viruses can be
spread from room to room by central air conditioning or heating
systems, so an off-premises location is preferred.
New Bird Examination
The second most valuable step for a new bird
owner is to locate an avian veterinarian, preferably one who is a
member of the Association of Avian Veterinarians. Check with local
bird clubs, your closest veterinary school, or check out www.AAV.org. The AAV recommends a
veterinary examination of any newly purchased bird within three
days of purchase. If disease is present, the possibility of
diagnosis and appropriate treatment is enhanced by early detection.
Many serious diseases are not visually evident.
Even if the new bird checks out "normal," results
of diagnostic tests performed at the initial visit provide valuable
reference for subsequent examinations.
Components of the Exam
History- What you know about the
background of your bird such as its age, sex, origin, length of
time in the household, diet, and caging, can be very important
information in determining and maintaining its overall health. 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 if the
owner has: 1) purchased bird toys from a pet shop that houses
birds; 2) visited other aviaries, bird shows, or bird markets; 3)
boarded the bird with someone who also owns birds; or 4) had a
caretaker who owns birds come over to feed and water the
bird.
Physical Evaluation- Observation of the
bird in the cage may determine general body condition, obesity,
tumors, posture, attitude, and character of respiration. Actual
hands-on examination is essential for more accurate determination
of condition. Although many internal problems may not be evident
from physical examination, an experienced veterinarian is better
able to note an abnormalities in the feathers, skin, beak, eyes,
ears, nares, oral cavity, bones, muscles, abdomen, and vent.
Weight- Once a bird is an adult, its
weight should remain relatively constant. Checking the bird’s
weight, an important part of the annual examination, will give
valuable information about the bird’s health. Weight should be
measured in grams, not ounces, to detect small changes.
Occasionally weighing the bird at home will provide an idea of
comparative gain or loss. Small electronic gram-scales are suitable
for home weight comparisons. For a larger bird, be sure the scale
goes to the desired weight range.
Testing Procedures
Depending on the bird’s history, results of the
physical examination, species, age, and general condition, your
veterinarian may suggest some of the following diagnostic tests to
further evaluate the 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. A fecal sample can be
examined microscopically to determine the presence of
parasites.
Test for Chlamydophila- Several screening
tests are available for the detection of chlamydophila, which used
to be called psittacosis or "parrot fever." This is an important
part of the new-bird exam or annual checkup because the causative
agent, Chlamydophila psittaci, may be transmitted from birds
to humans.
Blood Test- A blood sample might be taken
to determine the amount and distribution of blood cells. This
information may reveal 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.
Virus Screening- Tests are constantly
being developed to screen birds for existing and emerging avian
viruses. The detection of viruses is especially important for
aviary birds or birds that have come from pet stores. Some viral
agents do not appear as clinical disease until the bird is under
stress, such as laying eggs, feeding young or weaning, or being
moved to a new home.
Microbiology- Your avian veterinarian may
recommend a culture of the choana (throat), cloaca (vent), crop
(esophagus), or some other tissue/fluid sample to determine
abnormal growth of bacteria or yeast. At the same time, antibiotic
sensitivity tests may be used to determine an appropriate
antibiotic if the bacterial growth requires therapy.
Radiographs- Bone fractures, size and
relative relationship of internal organs, presence of foreign
bodies or soft tissue masses such as tumors, and the condition of
lungs and air sacs are often evaluated with
radiographs.
Sex Determination- If you wish to know the
bird’s sex and it is not visually discernible; ask your avian
veterinarian. We offer DNA sexing which requires a small amount of
blood and results come in about one week.
Annual Checkups
Because birds mask symptoms of disease, signs of
the beginning stages of disease often go unnoticed. Annual checkups
are advised for early identification and management of potential
disorders. New information about birds is continually being
discovered. Occasionally consulting your veterinarian will keep you
up-to-date on recent advances. Ask your AAV veterinarian for the
latest information brochures and news releases from the Association
of Avian Veterinarians.
