Satin Bowerbirds - Yellow and Blue Objects

[Richard Lane <>]

Hello Jack and Geoff and others

I have photographs from two separate and geographically distinct performances (not just tidying up etc.), and they show males presenting both blue and yellow objects. 

For interest, I did a Google search for "male Satin Bowerbird performing" and then selected the "images" option. It revealed a remarkably high percentage of both blue and yellow objects when the image showed a male performing with something in its beak. Fascinating.

Hello Richard,  about 15 years ago I published on the Satin Bowerbird also liking yellow objects in addition to the traditional blue ones [see p90 of my article in CBN 28, pp87-95 (2003)].  While I have since seen further examples of this, I can’t recall them actually being used while the bowerbird was performing as opposed to decorations around the bower, often leaves or straws at the front, but also Sulphur-crested Cockatoo crest feathers (as in Geoffrey’s photo).  As I noted in my article how they manage to collect so many of these feathers is unclear.

Seeing this, I was reminded that all of the male Satin Bowerbirds that I have seen performing (which is not a statistically significant number but photographs illustrating this can be supplied upon request) have been carrying both a yellow object and a blue object with their beak. Why is their penchant for blue objects always noted in the literature, whilst I have not read anywhere about the yellow objects that they present to females ?
