Last Friday white egret Snehurka got a ball of ice and snow, stuck to his left wing, and he looked like ill. Libor caught him and removed the ball and Snehurka "recovered".
Yes, Snehurka turned out to be a male, not a female.
Today in the morning female mute swan Beta suddenly died for some unknown reason, probably bird flu. The pond will be dried and all the other birds moved to aviaries.
