There is also a fascinating Sefer Hachinuch mitzva 187, who explains that we don’t cover the blood of a behama because it went on the mizbeach as an atonement whereas most birds were not sacrificed with wild animals, so there blood did not go on the mizbeach being considered life which was put out, must be covered like being burried to show our dismay for death.
