Hello Chris,
If you read Lee's email he mentions that they were watching bowerbirds
around a housing estate. It sounds like suburbia.
Also, I think you are stretching it a bit if you say that an increased
availability of blue objects is causing a surge in bowerbird bower
development! And even if it is- does it matter? The natural ecology of
many areas in suburbia is way out of whack already- trying to maintain
some sort of artificial approximation of what used to be natural is
impossible. Let the bowerbirds enjoy their new and brighter bowers! In
my opinion, it is great that the Satin Bowerbird is surviving so well in
suburbia. Let's just enjoy their presence and crazy behaviour.
Its a really minor conservation concern- there's a lot worse things
going on out there that are worth worrying about.
Cheers
Mick

Hi Michael and others,
The Bunya Mountains are hardly an urban situation. The location Lee
describes is either within the boundaries of the Bunya Mountains
National Park, or right on the edge, depending on exactly where he set
his blue objects down. Either way, perhaps not the most appropriate
behaviour in a National Park environment.
Personally, all the best bowerbird bowers I've seen have had all
natural objects around them. I have often wondered if we are changing
the breeding ecology of Satin Bowerbirds with the overabundance of
blue objects, and with feeding. I've definitely read that there is a
much higher than "normal" density of bowers around O'reillys and Binna
Burra in Lamington National Park. It would be an interesting if
difficult area to conduct a study into.
