This room was obviously not formed like the other niches in this cave. 
Unlike the others, sharp rocks poke out all over, making it look like a
death trap of sorts.  Entirely uninhabitable by bird or fugitive human, this
ledge also slopes sharply toward the center of the collection of chambers,
which leads to the floor far below.
