A
male bowerbird builds large huts from sticks and decorates them, sometimes even using berry juice as wall paint.
In 2012 ecologists Laura Kelley and John A. Endler, both then at Deakin University in Australia, confirmed that among the
great bowerbirds in Queensland, how well a male generates these illusions can predict his mating success.
Bigger is better for a
female bowerbird in search of a mate, and males are prepared to manipulate perspective to convince them.
Endler is now making videos
of bowerbird flirtations to see if a greater gradient results in increased mating success.
From here, follow the Waterfall Way scenic drive an hour inland to reach the UNESCO - listed rainforest of Dorrigo National Park — it's brilliant for birdwatching, with
satin bowerbirds among the most prized sightings.
BIGGER is better for a female
bowerbird in search of a mate, and males are prepared to manipulate perspective to exploit this.
Male
bowerbirds build bowers — twig tunnels furnished with decorations — that are designed to entice females and act as a stage for courtship and copulation.
Differences in bower decoration within a single population of
spotted bowerbirds come about because of local traditions, a new study finds, demonstrating a type of social learning rarely seen outside of primates.
Real bowerbirds like to make things and plant flowers, all as part of an elaborate mating ritual.
Male
bowerbirds use forced perspective — and impressive building skills — to woo the females of the species.
For bowerbirds however, their bachelor pads — or bowers — are the selling point.
Endler is now using video cameras to test
whether bowerbirds that create the best visual illusion increase their mating success.
Poring over hundreds of hours of footage back in his lab at the University of Maryland in College Park, Borgia came across a male
streaked bowerbird belting out an extraordinary soundscape.
Since the EPUBs are distributed on CD, you could just add the files separately to the CD (
as bowerbird suggested).
What does it say
about bowerbird perception that the males observed in the experiment thought the robot was realistic enough to mate with?
Great
bowerbirds go one step further, creating optical illusions to intrigue the ladies and make them more likely to mate.
A male
bowerbird typically lives 30 years and begins collecting objects for his courtyard by age 5.
Endler then reversed 15
bowerbird courts, placing larger objects close to the opening of the tunnel, but their owners would have none of it.
Last September John Endler, an evolutionary ecologist at Deakin University in Australia, reported that
bowerbirds seem to use their trinkets to create a carefully plotted optical illusion.
Bowerbirds produce elegant bachelor pads (bowers) that would probably elicit favorable reviews from Manhattan art critics — as long as you auctioned them at Sotheby's and did not reveal that they were created by birdbrains.
Younger males, who don't have as much home - decorating game as the
older bowerbirds, will sneak in to other bowers and steal decorative items, like blue feathers, shells, bright berries, and colorful bits of plastic.
Patricelli and her research team spent a month and a half in a little shack in the middle of the rain forest trying to find ways to drape the skin of a real female
bowerbird over her metal creation.
Even before Kaplan and Miklósi introduced AIBO to Fido, a handful of animal researchers in Europe, the United States, and Japan were busy conducting experiments with their own animal robots, including a
flirtatious bowerbird and a furry white ratbot.
Borgia and Patricelli wanted to use a male robot as well, but male
bowerbird behaviors are too complex to reproduce with today's robot technology.
Patricelli's robot showed with its movements that female
bowerbirds control the intensity of male mating displays.
And I have no idea
who bowerbird is, but who ever it is, please, find someone else to pester — many of us grew so tired of your badgering of Bill McCoy on his blog at Adobe.

According to a team of British researchers
studying bowerbirds in Australia, the species» elaborate courtship ritual inadvertently led to the proliferation of flowers near their little constructions, called bowers.
The
satin bowerbird uses a wad of bark with which to apply the paint; the bower painting varies greatly among individual birds, regardless of their color or maturity (BR 37 - 9).
In nearly every species
of bowerbird, males impress females by building elaborate structures called bowers: long, twiggy corridors that open to a courtyard decorated with small objects.
Joah Madden of the University of Cambridge, U.K., and his colleagues examined bowers built by the
spotted bowerbird, Chlamydera maculatain Taunton National Park in Queensland, Australia, and found local preferences for particular bower ornaments.
She sat down with a mechanical engineer and watched videotapes of
real bowerbirds.
Showy birds» nests have attracted many fans across the ages, from
female bowerbirds to 19th - century young naturalists.
In your article on the optical illusion used by
male bowerbirds to get a mate, you write that researcher John...
Bowerbirds, a family of passerine birds which live in the rain forests of Australia and New Guinea, build bowers laid out so that the sun will not blind the bird while he dances in the presence of the female.
Male
bowerbirds, like the males of so many species, lure mates with displays of wealth.
The Courtyards Gray and white bones, shells, and pebbles festoon most great
bowerbirds» courtyards.
This, Endler believes, is
the bowerbird's tactic.
Male great
bowerbirds (Chlamydera nuchalis) build intricate bowers — tunnels built from interlaced twigs.
While it's unknown why
the bowerbirds place the objects as they have, he says, «it is reasonable to expect it will improve mating success».
Evolutionary ecologist John Endler of Deakin University in Australia discovered that among great
bowerbirds, pigeon - size birds native to northern Australia, females are dazzled by craftsmanship.
Endler believes this is
the bowerbird's tactic.
