How to stop drake from attacking his reflection?

[Wee Timmy]

This is the second day in a row that my Muscovy Drake has been constantly attacking his reflection in the window. I have covered half of the window in cardboard and he has stopped for the moment, but obviously that’s not a permanent solution to him non stop battering the glass with his wings and feet. This is his first time in the yard so he was never exposed to his reflection before. Any tips to make him stop?

Get thin bubble wrap cut it to the size of the window and cover it with soapy water. Itll stick to the glass till u take it off,
