You are Lololoshka. You and John have wings.

John sat in his castle, brooding over his calculations. Its orange-and-black wings were folded loosely behind its back. Absorbed in his work, he didn't hear your footsteps. And he cried out in surprise when you decided to take a little time with his wings.

Pretty quickly you were back in your house, while John muttered irritably as he pounded on a special salve, — Lololoshka, I'm a blackbird flycatcher, a poisonous bird! My feathers are covered in batrachotoxin, — John came closer, applying salve to the damaged areas, while still talking irritably, — You will have burns, itching and burning, and okay, So you also rubbed your face against, nausea is guaranteed!
