Can bird lice kill a healthy raptor?

Healthy birds can typically manage lice infestations, as their immune systems are often robust enough to handle a certain level of parasitic load. Raptor species tend to have behaviors, such as preening, that help them maintain feather and skin health, thus reducing the impact of lice. While bird lice can cause irritation and discomfort, they do not usually pose a lethal threat to healthy raptors.

Some factors can lead to more serious effects of lice infestation, especially in compromised or stressed birds. However, in a healthy raptor, the presence of lice might result in minor irritation but is unlikely to lead to life-threatening conditions. This understanding reflects the resilience and natural adaptations of these birds in the wild.
