Volume 3, Book 29, Number 54 :Narrated by Hafsa

Allah's Apostle said, "It is not sinful (of a Muhrim) to kill five kinds of animals, namely: the crow, the kite, the mouse, the scorpion and the rabid dog."

Is this true

According to Islam, any animal which is not harmful and even if it is harmful but not going to harm you, then there is no reason to them kill them. Yes if it’s around ones living area and there is a possibility that it can harm, then one can kill otherwise no reason to kill them.

But about the crow, mouse and kite etc there is no reason to kill them, it’s beyond our understanding.
