What is typically not a concern for healthy birds regarding avian lice?

Healthy birds are generally capable of coping with avian lice without experiencing severe health issues. These lice are often a nuisance but not typically a direct threat to the overall health of a well-maintained and robust bird. Healthy birds can manage light infestations through their natural grooming behaviors.

Grooming is a critical part of a bird's daily routine, allowing them to remove lice and maintain feather condition. Additionally, although avian lice might infest any bird, they are more commonly observed on those that are weakened or stressed, which could lead to infestations being more severe in those cases rather than healthy individuals.

The focus on healthy birds demonstrates their resilience against potential health threats posed by lice, as they do not generally cause significant harm. Thus, while treatments might be considered to prevent infestations or alleviate discomfort, the primary concern of severe health issues associated with lice is usually related to sick birds rather than healthy ones.
