Overpreening

Overpreening is a behavioral response observed in animals, most commonly in birds, where they engage in excessive grooming of their feathers. This can manifest as repeated stroking, plucking, or manipulating of specific areas of their plumage. While preening is a normal and essential activity for maintaining feather health, waterproofing, and removing parasites, overpreening goes beyond these functional requirements.

The underlying causes of overpreening are varied and can include psychological distress, stress, anxiety, boredom, or frustration. Environmental factors such as inadequate cage space, lack of social interaction, or insufficient mental stimulation can contribute to this behavior. In some cases, overpreening can be a symptom of an underlying medical issue, such as skin irritation, infection, or parasitic infestation, which the animal is attempting to alleviate through grooming.

This excessive behavior can lead to feather damage, bald patches, and even skin lesions. In severe instances, it can significantly impact an animal's ability to regulate body temperature and can make them more vulnerable to environmental conditions and predators. Identifying and addressing the root cause is crucial for managing overpreening. This may involve environmental enrichment, behavioral modification techniques, and veterinary consultation to rule out or treat any medical conditions.
