Feather loss or damage in a raptor may indicate the presence of which type of parasites?

Feather loss or damage in raptors is commonly associated with external parasites. These parasites, which include mites, lice, and fleas, can invade the skin and feather follicles, leading to irritation and subsequent feather loss or degradation. The presence of these pests can cause discomfort to the bird, prompting behaviors such as feather plucking or excessive preening.

In contrast, internal parasites generally do not have a direct impact on the feathers, as they inhabit different areas of the body and often affect the bird's overall health rather than its external appearance. Coccidiosis, which affects the intestinal tract, and frounce, a respiratory condition caused by a specific parasite (Trichomonas), are also unrelated to feather condition, further highlighting that external parasites are the primary candidates when it comes to feather issues. Understanding the impact of external parasites is essential for maintaining the health and well-being of raptors in care.
