What ectoparasite may result from the removal of pigeons or house sparrows?

The correct response indicates that mites are the ectoparasites that may arise from the removal of pigeons or house sparrows. This is significant because both pigeons and house sparrows often host various species of mites, which can then become problematic for humans and other animals in the vicinity once the bird population is reduced or removed.

When these birds are taken away, the mites that were previously feeding on them may seek alternative hosts, leading to an increased chance of infestation in nearby living environments. Mites, particularly bird mites, can survive for some time without their avian hosts, which allows them to potentially invade homes or other structures where people or pets may be present.

Understanding this relationship highlights the importance of managing not just the bird population but also being aware of the ectoparasites that may proliferate as a consequence. This knowledge aids in implementing appropriate pest control measures to address potential infestations effectively.
