Birds often shake for various reasons, some normal and others indicating an underlying issue. Understanding these contexts is important for bird owners and enthusiasts, helping to distinguish typical actions from signs that may warrant concern.
Normal Behaviors
Birds commonly shake as part of their healthy functioning. One reason is to manage body temperature. Birds shiver to generate heat when cold, warming themselves through muscle contractions. Shivering can indicate the environment is cooler than their comfort range, typically 65° to 80° F (18° to 27° C).
Shaking also plays a significant role in feather maintenance. Birds frequently shake to resettle feathers after preening, bathing, or ruffling them. This action, called a “rouse,” helps align feathers for efficient flight and removes dust, dander, or excess water. After a bath, birds shake to shed water and dry themselves.
Excitement or anticipation can also cause shaking. Birds may exhibit a slight tremor when highly stimulated. This can occur before feeding, during playtime, or when greeting a familiar person. This type of shaking indicates engagement and happiness in a given situation.
Indicators of Trouble
While some shaking is normal, certain types indicate distress or health problems. Birds may shake in response to fear or stress from perceived threats. Loud noises, new environments, unfamiliar people, or handling can trigger this trembling. This shaking typically accompanies other signs of unease, such as retreating or appearing tense.
Shaking can also be a symptom of illness or weakness. If a bird is experiencing pain or a systemic health issue, trembling may occur. This kind of shaking often comes with additional signs like lethargy, ruffled or puffed feathers, changes in appetite, or altered droppings. These combined symptoms suggest the bird’s body is struggling.
Neurological issues can also manifest as shaking. Conditions affecting the brain or nervous system, injuries, or toxin exposure can cause tremors. For instance, lead poisoning or certain viral infections can lead to shaking, along with other neurological signs like loss of balance, seizures, or disorientation.
Recognizing Serious Concerns
Assessing the severity of shaking involves observing the bird’s overall condition and behavior. Pay attention to contextual clues, such as posture, activity level, and eating habits. Determine if the shaking is an isolated incident or accompanied by other concerning symptoms.
The duration and intensity of shaking also provide important clues. Persistent, severe, or unexplained shaking that does not resolve quickly warrants attention. Continuous trembling without a clear normal cause indicates a need for further investigation.
Contacting an avian veterinarian is advisable in specific scenarios. This includes when shaking is accompanied by lethargy, loss of balance, difficulty breathing, or significant changes in droppings. A vet visit is also appropriate if shaking is severe, continuous, or if you suspect toxic exposure or injury.
