Check out the article "Singing Stairs" in the January 16, 1999, issue
of Science News. It summarizes a paper given by David Lubman at the
October, 1998, Acoustical Society of America meeting. (I was at that
meeting, but unfortunately missed this talk).
Lubman notes that the *decreasing frequency* of the chirp is reminiscent
of the call of the quetzal bird; thus his theory that the Mayan's
constructed the stairs deliberately to mimic the bird's call.
This theory is somewhat in dispute.
