Possible rabbit sound?

Question
My wife and I have sited three rabbits in our backyard this spring.  This isn't uncommon as we have all kinds of critters running around back there.  Yesterday on our return home from errands, I noticed a rabbit dead (I assume, I have not been out yet today to check if it is still there) on the side of the road, obviously hit by a car.  I thought nothing of it at the time.

However, twice last night, around 1 am and again around 2:30 am, I heard this very bizarre noise outside, along with rustling in the underbrush and tall grasses near where the dead rabbit was.  It was a piercing sound, and at first I thought someone was screaming in our driveway.  The noise repeated several times during each occurrence, during which I ruled out a person or a dog.
My guess is that the rabbit's mate discovered the body, and was screaming, but after some research the recordings I've heard are of a slightly higher pitch than the sound I heard.  The noise projected very, very far and I could hear it echoing throughout our suburb, and it was also bone-chilling to say the least.
Would this behavior be typical of wild rabbits?  Could the noise be a distress call from a mate indicating alarm/stress or something?

Hello Adam!

Rabbits produce that screaming sound usually only when they are in pain, so if it was possible that the rabbit was unconscious at first and then regained consciousness with several broken bones and hurt insides, that would be one, very painful, reason you heard the screaming sound. Of course, in that kind of pain the scream will be very bone-chilling.

Of course there are other explanations. It could also be from the mate, because some rabbits bond forever and become very depressed after the loss. Or the group of rabbits could feel threatened somehow because they can become very cautious when they witness one being killed. It could be from another rabbit who was with that one (They like to play with friends! Not alone.) and just had a part of it run over that was extremely injured but able to limp to a bush.

I wouldn't say it is typical, but it isn't unusual. Something to check is if they are wild rabbits or if they look like domesticated rabbits released by a neglectful owner, because they don't survive well in the wild. It can stop by itself, but if you are worried about another hurt bunny, look around, probably close by, and if you find it, take it to the vet.
