A bird dander allergy is an allergic reaction to proteins found in the skin flakes, feathers, saliva, and droppings of birds. When a person with this allergy comes into contact with these allergens, their immune system overreacts, leading to symptoms such as sneezing, coughing, wheezing, itchy eyes, and skin rashes. Bird dander allergies can be triggered by both domestic and wild birds, making it important for individuals with this allergy to avoid exposure to birds and their environments. **
