What are wing worms and how do they affect the health of birds?

Wing worms are parasitic insects that infest the wings of birds, causing irritation, inflammation, and potential infection. They can affect the health of birds by weakening their ability to fly, leading to reduced mobility and difficulty in foraging for food. Additionally, wing worms can cause stress and discomfort for the birds, impacting their overall well-being and potentially leading to further health complications.
