Musnad Abu Ya'la al-Mawsili 153:83

Amr narrated to us, Sufyan narrated to us, from al-Zuhri, from Salim, from his father, who said: The Prophet (peace be upon him) was asked: "What animals may the person in ihram kill?" He said: "Five animals, there is no blame upon the one who kills them in the Sacred Precinct (Haram) or outside of it (Hill): the crow, the mouse, the scorpion, the kite, and the vicious dog."
