Macaws are intelligent and expressive parrots, but they instinctively hide illness until it is advanced. Early detection of health problems is crucial for their wellbeing because a subtle change in behavior or droppings can signal a serious issue. Our editorial team explains the key signs of illness in macaws, so you can act promptly and give your feathered companion the best chance at recovery.
Recognizing these signs requires knowing your macaw’s normal behavior, appetite, and droppings. Any deviation from the norm warrants a checkup with an avian veterinarian. This guide covers the most common indicators of illness in macaws, from physical symptoms to behavioral changes.
Changes in Droppings
Macaw droppings consist of three parts: a green or brown solid (feces), a white or cream urate, and a liquid urine. Healthy droppings are well formed and consistent. Illness can cause changes such as watery or discolored feces, blood, undigested seeds, or a foul odor. Polyuria (excess urine) may indicate kidney issues or diabetes, while green or yellow urates can signal liver disease. Any persistent change in color, consistency, or volume should prompt a vet visit. Collect a fresh sample for the avian vet if possible.
Behavioral and Activity Changes
Macaws are usually active, playful, and vocal. A sick macaw often becomes quiet, lethargic, or withdrawn. It may sit fluffed up on the bottom of the cage or sleep more than usual. Aggression or irritability can also signal pain or discomfort. Conversely, some macaws become unusually clingy or seek attention. Loss of interest in toys, foraging, or interaction is a red flag. Any sudden change in temperament warrants investigation.
Appetite and Weight Changes
Macaws have a high metabolism and need a balanced diet of pellets, fresh vegetables, fruits, and nuts. A sick macaw may refuse food or eat less than usual. Weight loss can be rapid and dangerous. Weigh your macaw weekly with a gram scale to detect trends. Conversely, increased thirst or appetite can also indicate illness, such as diabetes or parasites. Check the crop for delayed emptying, which may suggest infection or blockage.
Physical Signs of Illness
Look for nasal discharge, sneezing, or wheezing, which suggest respiratory infection. Macaws are prone to aspergillosis, a fungal disease. Check the eyes for swelling, discharge, or dullness. The beak and nails should be smooth; overgrowth or flaking can indicate malnutrition or liver disease. Feather condition is also telling: a sick macaw may have ruffled, dirty, or broken feathers, or may pluck due to stress or illness. Vomiting or regurgitation (not bonding behavior) is serious. Examine the vent area for staining or swelling.
Respiratory and Neurological Signs
Macaws can develop respiratory issues from drafts, poor air quality, or infections. Signs include tail bobbing, open-mouth breathing, clicking sounds, or a change in voice. Neurological signs such as head tremors, circling, seizures, or loss of balance may indicate heavy metal toxicity (common in macaws from chewing unsafe items), vitamin deficiency, or infection. Any of these symptoms require immediate veterinary attention. Macaws are sensitive to fumes from Teflon, candles, and cleaning products, which can cause sudden illness.
