Red-rumps, Gould, and mistletoe

["Peter Cranston via Canberrabirds " <>]

Nice observation Geoffrey: with Gould, accuracy is always the best guess. The 'warped mistletoe berries' are indeed scale insects, Cryptes baccatus, known as wattle tick scales.

is a nice illustration, with attendant ants feeding on the secreted honeydew. Gould, or Richter, accurately shows the posterior dark spot, the anal area, from which the honeydew is excreted (the feeding mouthparts of the head end are embedded in the plant tissue).  Great naturalists both

There are certainly a lot of Red-rumped Parrots around at the moment.  I'm seeing groups of up to 40 or so feeding on various urban grassy patches.  Coincidentally, while on an online excursion reminding myself about the remarkable publishing feats of John Gould, I came across an example of an uncoloured Red-rump print held in South Australia (first link below).  The detail is remarkable. Look at the shadows of the mistletoe leaves on the back of the male.  Someone, possibly Richter under Gould’s supervision, took the trouble to draw those slight shapes on a stone tablet. I was also keeping an eye out for scale insects.  There is an ambiguous clump on a twig here.  However I take this to be an intended, if unrealistic,  cluster of mistletoe fruits that Gould wanted to include as an added touch of a remembered Australia.  Second link is about how lithographs were made,  third one about mistletoe.
