True or False: Bird lice can kill a healthy raptor.

Bird lice are ectoparasites that primarily affect birds, including raptors, by feeding on their feathers and skin. While they can cause discomfort, irritation, and even stress in healthy birds, they are not typically lethal to an otherwise healthy raptor. Healthy raptors have robust immune systems that can usually manage low to moderate infestations of these parasites without significant impact on their overall health or survival.

However, in cases of severe infestations, or if a bird is already weakened by other health issues, the lice could contribute to deterioration in health. This highlights the importance of ensuring that raptors are well-cared for and maintaining their health to fend off infestations effectively. The statement in the question doesn't hold true in the context of a healthy raptor, which is why the answer is appropriately identified as false.
