My pigeons have this condition: See photos? Wondering if it's contagious? I'm starting to experience some similar physical ailments! What would you label this abnormality as?

Hello, Today we rescued a pigeon for the first time and we don't have much experience in handling the same. The birdy is not well, and their are warts/lesions on her beak/eye area. I have attached a close up photo of her face. Can you please help identify the problem and how to help the bird...
