Lonely duck makes unknown whistling noise

You can provide him with a mirror till he recovers. Then he won't feel so alone..
Best wishes..

Funny story, our duck is rather weird. When I hold him and look in a mirror he's fine, but once I placed a smaller mirror in front of him standing on the floor he started peeping like crazy, flapping his wings trying to get away from it. I don't understand what he's so afraid about, he saw his brother last 4 days ago.
