Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah, may Allah bless him and grant him peace, said, "There are five kinds of animal which it is not wrong for some one in ihram to kill: crows, kites, scorpions, rats and mice, and wild dogs".
The Prophet Muhammad ﷺ also taught us about mercy and kindness towards all living things including animals. He said “Whoever is kind to the creatures of God is kind to himself” (Sahih Muslim). This hadith reminds us that even though it may be permissible to kill certain animals during Ihram for a specific purpose, we should still show mercy towards them by not killing them unnecessarily or out of malice or cruelty.
