Male bowerbirds prefer colorful human items to decorate bowers

Seems like the major difference with human objects is simply that they don't decompose. Colorful fruits and leaves will only last so long, but with glass and plastic, the bird can just keep adding to the collection.

Which raises the question, is this a true change in behavior, or is the only major change that the urban birds don't have to discard aging items?

I can't remember if it was Bowerbirds specifically, but I remember there was a big fuss about milk bottle rings being blue, because some birds were getting the rings around their necks and suffocating. Satin Bowerbirds, or something like that?
Yes. Satin Bowerbirds love bright blue things. We have a nest near our place on the South Coast of NSW.

Here’s a photo I took a while ago of a nest in Tathra NSW.

Which is why you should always cut any sort of plastic ring/circle that goes in recycling or garbage. Also rinse and flatten - the tops at least - of food cans. Lots of animals get their heads/snouts stuck in cans. Rinsing the food out helps prevent them from sticking it in to begin with. Loads of vids on YT showing cops and people helping out animals in this predicament....

Then the team removed all existing decorations from each bower and created a mixed slush pile of 10 randomly selected urban bowers and 10 randomly selected rural bowers [...] After recording the data, all the original decorations were returned to their bowers.
What a confusing experience this must've been for the poor birds. One day, all your shinies up and disappear, only to be replaced by a bunch of new stuff you've never seen before. Then, a couple days later, after you've gone through all the trouble of picking through this new stuff, all your old stuff suddenly reappears!

TIL Stephen Wright is a bowerbird.

As far as things researchers do to wildlife, this is pretty tame.

I've met folks like that, who fill up their digs with all kinds of tchotchkes, gimcracks, baubles, gewgaws and colorful gizmos, and then hope to attract a mate. Oddly enough, it often seems to work. Maybe we aren't all that far removed from our dinosaur and pack-rat ancestors.

I'd even suggest human society has come to artificially boost this behavior?

"Back then", in evolutionary terms, this kind of advertisement was probably a representation of a potential mate's individual creativity and skill at sourcing items in a direct competition between suitors.

Today, this individual skill at procurement has largely been replaced by the wealthiest members of society more often abusing a privileged upbringing to then just pay others for bringing them whatever item gets popularized by media influencers.
And then our entertainment machinery ensures that young kids grow up believing this is what they ought to value and aspire to.

Any of them collect the venomous octopus....?


Kidding of course, that would be silly.

What I like about articles like this is that they sometimes make me question what I think I know.

I was going to post that the UK Magpie is similarly attracted to shiny objects, but it turns out that's not actually true. In fact they apparently display neophobia where shiny objects are concerned and are more likely to interact with dull objects. Being corvids though they are still worryingly clever and curious about stuff.

I remember someone saying that if you befriend a crow, you befriend the entire flock (or murder). Similarly, if you anger or hurt one, the entire flock will seek revenge on you.

Someone (almost certainly anecdotal, but funny) once posted "Help! I accidentally killed a crow and now the rest won't leave me alone! What do I do?", and the answer he got was "Move house. Seriously. You're fucked."

I'm a little surprised about the colour preferences mentioned in the article, because I've seen a few bowers - and every bower I've seen featured blue items. I thought that blue was a universal characteristic of bowers. Apparently I was wrong about that.

The article talks about rural vs urban. But I wonder if there are significant differences correlated with country.

I believe this is a uniform experience across the natural world....
