Panting or Trouble Breathing


First, call and make an appointment with an avian vet. Parakeets are prone to respiratory infections and your pet will need the medical attention of a certified veterinarian. Next, cover two or three sides of the bird cage and place a heat lamp over your bird. Keep the temperature between 80F and 86F (27C – 30C). If you only have a lamp be sure the bulb is no greater than 25 watts.

Droppings


If you notice a drastic change in your bird’s droppings such as a change in color, it becomes watery, or appears looser than usual. Also make note of any seeds in the droppings. Sometimes a change in droppings may be caused by a change in diet or brand of food.

Appetite


Another common sign of a sick parakeet is a change in appetite. If you bird stops eating or you ntice a change in his eating habits, then you be on the lookout to see if your bird begins to suddenly lose weight. This is often a telltale sign that your bird is sick, and you should contact a vet immediately.

Feathers


If your parakeet’s feathers are ruffled or puffed up for long periods of time, then something is wrong. If you find your bird’s feathers are discolored, you should also be aware of danger.

Discharge

A very serious symptom that you must look out for is discharge from your parakeet’s eyes and nostrils. This is often accompanied by sneezing or swelling around the eyes. These are very serious conditions that should be attended to by a vet.

Biting


Your parakeet didn’t learn biting in one day, and you’ll have to use positive reinforcement in order to stop it from biting over the course of several days. In order to successfully do this, I suggest you watch the videos available here.
