also are said to decorate their bowers by 'painting with a mixture of
saliva and charcoal or saliva and green liverwort', using a stick as a
paintbrush (Vellenga, 1970). The Vellengas also did a lot of work on
SBBs according to Rowley. I wonder if that latter claim has ever been
confirmed?
Yes, it has. Here in the Blue Mountains you can often see the
dark-coloured paste which has been painted onto the inside walls of
the bowers. Once I watched a bird from close quarters painting its
bower using a piece of lichen or moss as a paintbrush - this was at
Leura very near where the Vellengas did their studies.
And on the topic of natural, or pre-European, bower decorations, the
following is from an account of a walk in the northern Blue Mountains
which I posted on Birding-Aus in November 2000:
"Near the end of the day I found a lavishly decorated Satin
Bowerbird's bower, on a ledge between boulders halfway up a steep
hillside. It was far enough from civilisation that the majority of
the decorations were natural. These included a large number of blue
Crimson Rosella feathers, blue Stypandra flowers, yellow wattle
flowers, pale greenish and brown leaves, a number of greenish
cocoons, a large huntsman spider (almost, but not quite, dead and
looking like it had been placed there by the bird) and, to our
surprise, two freshly-picked beautiful yellow flowers of Dendrobium
speciosum - the showiest of all the local orchid species. This of
course led us on a hopeful search for the plants nearby, but we
remained outdone by the orchid-finding skills of a bowerbird."
