Zevachim 85 - These Must be Removed from the Altar
The wool on the heads of lambs and the hair on the beards of goats, as well as bones, sinews, horns, and hooves all have a special law: as long as they are attached to the burnt-offering they came with, they should be brought up on the Altar together with the offering, but if they are separate from it, they should not be brought.
Is a sodomized bird valid for the Altar? Since the relationship is not reciprocal and the bird cannot sodomize a human, then perhaps even if the bird was sodomized, it can still be brought as a sacrifice, or, after all, since a sin was committed with it, maybe it is invalid? The answer: since the sodomized bird is not mentioned in the list of disqualified offerings that may remain on the Altar because there are situation when they are permitted (bird cannot sodomize a human), then perforce a sodomized bird is never valid as a sacrifice.
