Mostly about my backyard chickens. (Boring, I know), but there are a lot of us out here. Mine are only kept as pampered pets. I could eat a neighbor's chicken, but not MINE. There may be a comment on current events only if I get riled up enough. And there will always be a cartoon or a joke to cheer us. I promise to try my very best to respond to comments. Now I have to figure out how this blogger thingy works....
Inspired by Japanese origami and powered by an electric motor, this drivable replica of a Lexus IS sedan is made from 1,700 sheets of laser-cut cardboard.
Lexus’ motto, Creating Amazing,
means ‘relentlessly pushing the boundaries of design, technology,
craftsmanship and customer care. An experience as amazing as the car
itself.” To illustrate that philosophy, Toyota’s luxury vehicle marque
has created a rather amazing automobile: an origami-inspired, full-size
rolling sculpture whose body and interior are composed of precision-cut
cardboard. The replica of a Lexus IS sedan is fully drivable as well,
though one had best check for rain in the forecast before taking it for a
spin.
A
whopping 1,700 individually-shaped pieces of cardboard went into the
replica Lexus IS sedan and although 3D-printing was NOT involved, plenty
of computer-aided design was required. Technicians scanned each
component’s details into a computer, which then calculated the precise
dimensions of each segment. Then it was off to a programmable laser
cutter where the sheets of cardboard were individually cut and made
ready for assembling together.
Not
every part of the replica Lexus is made of cardboard, mind you – a
robust steel and aluminum sub-frame hidden deep within the warren of
cardboard panels supports the electric motor required to motivate the
sculpture. Other functional non-cardboard components include door hinges
and headlights.
The
cardboard car was built for Lexus by London-based specialist
companies LaserCut WORKS and Scales and Models. Lexus provided a
three-dimensional digital model of their IS sedan, which company
technicians then divided into working sections. Each section was then
digitally rendered in slices just 10mm thick, resulting in a series of
two-dimensional profiles which were precisely laser-cut from cardboard
sheeting.
Organizing
the many similar yet distinctly different cardboard sheets was a
project in itself; each layer was given a unique reference number to
ensure there were no errors when it came to final assembly. At this
point, the computers yielded control to their human masters – actual
people worked hands-on using water-based wood glue to attach each
cardboard sheet to its neighbor. Since every application of the glue
required 10 minutes to set, the entire assembly process took three
months to reach the finish line!

Crows chasing that damn hawk:
Charlie had a fit! The hawk flew low over the pen. Charlie sounded a warning and the hens ran for the coop. He stayed and guarded the entrance to the pen for quite a while. He's all huffy and puffy here and I bet he would have attacked that hawk if it had tried to get one of his girls!
Bowerbirds/ˈbaʊərbɜːrd/ make up the bird familyPtilonorhynchidae.
They are renowned for their unique courtship behaviour, where males
build a structure and decorate it with sticks and brightly coloured
objects in an attempt to attract a mate.
The family has 20 species in eight genera. These are medium to large-sized passerines, ranging from the golden bowerbird at 22 centimetres (8.7 in) and 70 grams (2.5 oz) to the great bowerbird
at 40 centimetres (16 in) and 230 grams (8.1 oz). Their diet consists
mainly of fruit but may also include insects (especially for nestlings),
flowers, nectar and leaves in some species. The satin and spotted bowerbirds are sometimes considered agricultural pests
due to their habit of feeding on introduced fruit and vegetable crops
and have occasionally been killed by affected orchardists.
The bowerbirds have an Austro-Papuan distribution, with ten species endemic to New Guinea, eight endemic to Australia, and two found in both.
Although their distribution is centered on the tropical regions of New
Guinea and northern Australia, some species extend into central,
western, and southeastern Australia. They occupy a range of different
habitats, including rainforest, eucalyptus and acacia forest, and shrublands.
Behaviour and ecology
The Ailuroedus catbirds are monogamous, with males raising chicks with their partner, but all other bowerbirds are polygynous, with the female building the nest and raising the young alone. These latter species are commonly dimorphic,
with the female being more drab in color. Female bowerbirds build a
nest by laying soft materials, such as leaves, ferns, and vine tendrils,
on top of a loose foundation of sticks.
In courtship the male bowerbird will dance to the female in an attempt to attract her.
All Papuan bowerbirds lay one egg, while Australian species lay one to three with laying intervals of two days. Bowerbird eggs are around twice the weight of those of most passerines of similar size
– for instance eggs of the satin bowerbird weigh around 19 grams
(0.67 oz) as against a calculated 10 grams (0.35 oz) for a passerine
weighing 150 grams (5.3 oz). Eggs hatch after 19 to 24 days, depending on the species and are a plain cream color for catbirds and the tooth-billed bowerbird, but in other species possess brownish wavy lines similar to eggs of Australo-Papuan babblers. In accordance with their lengthy incubation periods, bowerbirds that lay more than one egg have asynchronous hatching, but siblicide has never been observed.
Bowerbirds as a group have the longest life expectancy of any passerine family with significant banding
studies. The two most studied species, the green catbird and satin
bowerbird, have life expectancies of around eight to ten years and one satin bowerbird has been known to live for twenty-six years. For comparison, the common raven, the heaviest passerine species with significant banding records, has not been known to live longer than 21 years.
The most notable characteristic of bowerbirds is their
extraordinarily complex courtship and mating behaviour, where males
build a bower to attract mates. There are two main types of bowers. One clade
of bowerbirds build so-called maypole bowers, which are constructed by
placing sticks around a sapling; in some species, these bowers have a
hut-like roof. The other major bowerbuilding clade
builds an avenue type-bower made of two walls of vertically placed
sticks. In and around the bower, the male places a variety of brightly
colored objects he has collected. These objects — usually different
among each species — may include hundreds of shells, leaves, flowers,
feathers, stones, berries, and even discarded plastic items, coins,
nails, rifle shells, or pieces of glass. The males spend hours arranging
this collection. Bowers within a species share a general form but do
show significant variation, and the collection of objects reflects the
biases of males of each species and its ability to procure items from
the habitat, often stealing them from neighboring bowers. Several
studies of different species have shown that colors of decorations males
use on their bowers match the preferences of females.
Uy and collaborators have shown that mate-searching females commonly visit multiple bowers,
often returning to the male several times, watching his elaborate
courtship displays and inspecting the quality of the bower and tasting
the paint the male has placed on the bower walls.
Many females end up selecting the same male, and many under-performing
males are left without copulations. Females mated with top-mating males
tend to return to the male the next year and search less.
Ernest Thomas Gilliard suggested the transfer effect,
in which he claimed that there is an inverse relationship between bower
complexity and the brightness of plumage. Gilliard suggests that there
is an evolutionary "transfer" of ornamentation in some species, from
their plumage to their bowers, in order to reduce the visibility of the
male and thereby its vulnerability to predation.
This hypothesis is not well supported because species with vastly
different bower types have similar plumage. Others have suggested that
the bower functioned initially as a device that benefits females by
protecting them from forced copulations and thus giving them enhanced
opportunity to choose males and benefits males by enhancing female
willingness to visit the bower.
Evidence supporting this hypothesis comes from observations of
Archbold's bowerbirds that have no true bower and have greatly modified
their courtship so that the male is limited in his ability to mount the
female without her cooperation. In toothbilled bowerbirds that have no
bowers, males may capture females out of the air and forcibly copulate
with them. Once this initial function was established, bowers were then
co-opted by females for other functions such as use in assessing males
based on the quality of bower construction. Recent studies with robot
female bowerbirds by Patricelli and collaborators have shown that males
react to female signals of discomfort during courtship by reducing the
intensity of their potentially threatening courtship. Coleman and colleagues
found that young females tend to be more easily threatened by intense
male courtship, and these females tend to choose males based on traits
not dependent on male courtship intensity.
The high degree of effort directed at mate choice by females and the
large skews in mating success directed at males with quality displays
suggests that females gain important benefits from mate choice. Since
males have no role in parental care and give nothing to females except
sperm, it is suggested that females gain genetic benefits from their
mate choice. However this has not been established, in part because of
the difficulty of following offspring performance since males take seven
years to reach sexual maturity. One hypothesis for the evolutionary
causation of the bowerbuilding display is Hamilton and Zuk's "bright bird" hypothesis, which states that sexual ornaments are indicators of general health and heritable disease resistance. Doucet and Montgomerie
determined that the male bowerbird's plumage reflectance indicates
internal parasitic infection, whereas the bower quality is a measure of
external parasitic infection. This would suggest that the bowerbird
mating display evolved due to parasite mediated sexual selection, though
there is some controversy surrounding this conclusion.
This complex mating behaviour, with its highly valued types and colors of decorations, has led some researchers
to regard the bowerbirds as among the most behaviorally complex species
of bird. It also provides some of the most compelling evidence that the
extended phenotype of a species can play a role in sexual selection and indeed act as a powerful mechanism to shape its evolution, as seems to be the case for humans. Inspired by their seemingly extreme courtship rituals, Charles Darwin discussed both bowerbirds and birds-of-paradise in his writings.
In addition, many species of bowerbird are superb vocal mimics. MacGregor's bowerbird,
for example, has been observed imitating pigs, waterfalls, and human
chatter. Satin bowerbirds commonly mimic other local species as part of
their courtship display.
Bowerbirds have also been observed creating optical illusions in their bowers to appeal to mates. They arrange objects in the bower's court area from smallest to largest, creating a forced perspective
which holds the attention of the female for longer. Males with objects
arranged in a way that have a strong optical illusion are likely to have
higher mating success.
Taxonomy and systematics

Though bowerbirds have traditionally been regarded as closely related to the birds of paradise, recent molecular studies suggest that while both families are part of the great corvid radiation that took place in or near Australia-New Guinea, the bowerbirds are more distant from the birds of paradise than was once thought. Charles Sibley's DNA-DNA hybridization studies placed them close to the lyrebirds; however, anatomical evidence appears to contradict this placement[citation needed], and the true relationship remains unclear.
Genus Ailuroedus
Note that the gray catbird (Dumetella carolinensis) and black catbird (Melanoptila glabrirostris) from the Americas and the Abyssinian catbird (Parophasma galinieri) from Africa are unrelated birds that belong to different families.
I put him near a pile of leaves so the gang wouldn't get him:
Had to put them back in the pen while we went to get extra gasoline. Our fat governor, Chrispy Cream, approved a 23 cent a gallon tax hike. It goes into effect today.
We paid $1.91 a gallon. THAT will be a fond memory....
It was a beautiful morning, but chilly.
This little stream is now full from all the rain we had last week:
Just a beautiful face, And oh my, those big eyes!
