The birds feed almost exclusively on the dome-like coverings, referred to as 'bell lerps', of certain psyllid bugs that feed on eucalyptus sap from the leaves.

This was adopted by early researchers [127] including C.E.G. Bailey who demonstrated its use for studying bird song in 1950. [128] The use of spectrograms to visualize bird song was then adopted by Donald J. Borror [129] and developed further by others including W. H. Thorpe. [130] [131] These visual representations are also called sonograms or ...
