Some people clean, others dance! 

Chelyabinsk Zoo staff showed how they clean Moses the ostrich's enclosure. While the workers use shovels to clean the enclosure and remove old hay bedding, he flaps his wings and dances. 

— Moses is so fond of hard-working women who also feed and cherish him, that he can’t help but sabotage the whole process by showing his feelings! noted at the zoo. 

The women, judging by the video, don't mind such a cheerful company and dance along with Moses, getting into a good mood.
