Sunan an-Nasa'i, Volume 3, Book 24, Hadith 2831 (DarusSalam)

It was narrated from Ibn Umar that the Messenger of Allah said: "There are five (animals) for which there is no sin on the Muhrim if he kills them: Crows, kites, scorpions, mice and vicious dogs."

أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ خَمْسٌ لَيْسَ عَلَى الْمُحْرِمِ فِي قَتْلِهِنَّ جُنَاحٌ الْغُرَابُ وَالْحِدَأَةُ وَالْعَقْرَبُ وَالْفَأْرَةُ وَالْكَلْبُ الْعَقُورُ ‏.‏
