Deer scream too. My first husband and I lived on an estate as caretakers, where deer came down from the forest to eat apples in the orchard and graze in the lawn. One nite we were awakend from a sound sleep by something screaming. I nearly scared us to death! He got a flashlight and his rifle and we went to check it out.We saw deer but nothing else. Went back the next day and only found deer tracks. We didn't think it could of been a deer. My husband had been raised in the woods in the mountains in a little canyon where no one else lived. We asked his dad about it and he said yes deer scream. Still not quite believing it we asked some relatives who lived on a ranch. The wife said she was outside hanging laundry and heard screaming and ran to the house to see if it was one of the kids. Kids Ok. She put them in the pickup and drove about and found a fawn trapped in a barb wire fence. The doe was screaming trying to help it out. Chris said she had lived on a ranch all of her life and had never heard a deer scream. So I guess it doesn't happen often.
