Loss of Appetite
If a bird who normally has a healthy appetite suddenly begins to show less interest in eating, it can be an indicator of stress and/or health problems. A good rule to follow in this type of situation is to schedule an appointment with an avian vet to make sure that the bird is not sick or injured. If your feathered friend’s health checks out, you can then begin to try and decipher possible stressors in your home that may trigger appetite loss in your bird.
Some birds exhibit stereotypical behaviors when they are stressed. These could include pacing, toe-tapping, and head swinging. They exhibit these behaviors to stimulate themselves when extremely bored.
Birds who begin to exhibit destructive behavior are quite possibly very stressed, and the most likely culprit in this scenario is boredom. Being the extremely intelligent creatures that they are, pet birds in captivity often do not receive a healthy amount of mental stimulation, which can lead to frustration, stress, undesirable behaviors, and even health issues.
To prevent stress in your pet bird, pay attention to your bird’s cues and try to avoid sudden changes to its lifestyle. If a cage has been moved and the bird doesn’t like it, move it back to slowly acclimate it to a new position. If new pets or family members are upsetting, again, try to acclimate the bird to the new member and focus on positive reinforcement (and treats). Being aware of the bird’s general sensitivities before any changes are made will help prevent stress.
