How To Tell If A Budgie Is Stressed

Some stressors can be removed immediately, enabling your budgie to calm down. Unfortunately, stress can lead to sudden death in budgies due to adrenal failure or a heart attack.
Budgies can be upset by changes to their environment, new faces, and even different foods. However, stress can’t be treated dismissively as it can be so harmful in a short amount of time.
Unfortunately, the symptoms can be hard to spot, especially true for new owners, who may overlook repeated behaviors or strange vocalizations.
In some cases, these behaviors are blamed on problematic birds. Then, the budgie is ignored or rehomed, only making the situation worse in the future.
Behavioral changes, like aggression or repeated behaviors, often manifest before physical symptoms, like self-mutilation and stress bars.
