Barry Birkey has informed me that the figure showing sonagrams of
piping worker bees is, indeed, on the web site.  He wrote:

The link is from this sentence:

The other type of loud sound in the hive is heard when the hive is
disturbed.

and goes to this page:
http://www.beesource.com/pov/wenner/croak_bip.htm

    I checked it out and found that those figures show those sounds
quite nicely.  Sorry that I was unaware of that possibility.
