#Fishermenâ##s Hackles Become Latest Fashion Trend Hackles#the long, skinny rooster feathers fishermen use to make lures are the latest trend in hair extensions.

Jim Bernstein, a flly shop manager, was warned that hair stylists would come banging on his door.

and made a beeline toward a display of hackles#the long, skinny rooster feathers fishermen use to make lures.

Feather extensions. Supplies at stores from the coasts of Maine to landlocked Idaho are running out

and some feathers sold online are fetching hundreds of dollars more than the usual prices. Im looking around the shop thinking hmmm,

It takes years and years and years to develop these chickens to grow these feathers.

And now, instead of ending up on a fly, its going into womens hair, #said Matt Brower, a guide and assistant manager at Idaho Angler in Boise.

The feathers are not easy to come by in the first place. They come from roosters that are bred genetically

and raised for their plumage. In most cases the birds do not survive the plucking.

At Whiting Farms, Inc.,in western Colorado, one of the worlds largest producers of fly tying feathers, the roosters live about a year

while their saddle feathers#the ones on the birds backside and the most popular for hair extensions#grow as long as possible.

As hair extensions, the feathers can be brushed, blow dried, straightened and curled once they are snapped into place.

Most salons sell the feather strands for $5 to $10 a piece. The trend has become so popular a company online even sells feather extensions for dogs.

The craze has also left hairstylists scrambling to find rooster saddle feathers as fly shops hold onto a select few for their regular customers.

He told me to stay out of his feathers, #she said. Whiting Farms is harvesting about 1,

500 birds a week for their feathers and still cant keep up with its current orders,

The company was the one that told Bernstein in Maine several months ago that rooster saddle feathers had somehow become the latest coveted hair accessory.

#Bernsteins inventory of rooster saddle feathers has long been depleted. About three weeks ago, he dusted off a rooster neck with feathers that had been set aside for fly tying classes at the shop.

Its not uncommon to find a package of rooster saddle feathers that would have cost around $60 at a fly shop now priced from $200 to $400.

At the Boise salon, Ambroz has stowed away enough feathers to last about six months. On a recent Tuesday evening, Emilee Rivers, 16, sifted through a pile of rooster saddle feathers looking for the perfect strands to frame her face.

She picked out four and handed them to the stylist, who bonded them together with hot glue before clipping them into Rivers blond hair.

This was really the first time scientists have been under a volcanic plume at sea and could really look at the immediate effects of the ash falling into the ocean Achterberg said.

Beneath the plume the scientists found that peak dissolved iron levels were up to about 20 to 45 times higher after the plume than they had been before the ash came along.

However the team estimated that the plume from Eyjafjallajã kull only triggered a 10 to 20 percent rise in carbon dioxide uptake by phytoplankton in the Iceland Basin compared to other years.

#Puzzling Plumage: Fractals Reveal Birds'Health For birds fractals are a turn on. A new study found that the complexity of fractal patterns on a bird's chest communicates the animal's fitness to potential mates.

Scientists studied male and female red-legged partridges (Alectoris rufa) which both display complicated black-and-white patterns of plumage on their chests.

and apparently the plumage of red-legged partridges. 5 Seriously Mind-boggling Math Facts In a new study scientists found that the healthier a bird is the more fractal-like its plumage becomes.

We have shown that fractal geometry can reveal biologically meaningful information encoded in a complex plumage trait:

The scientists found that fractal dimension predicted immune responsiveness meaning that partridges with more complex fractals on their plumage tended to have stronger immune systems.

After losing weight the same birds would grow in plumage with a lower fractal dimension than they had before while the birds

which serves as an anchor point for a big fan of tail feathers. Modern-day birds use pygostyles to help them fly

but oviraptors were not flying animals they had feathers but they didn't have big broad wings Persons said.

Past research has suggested that dinosaurs may have evolved first feathers for show not flight. Persons and his colleagues found that at least four known oviraptor species separated by 45 million years had pygostyles.

Although feathers on dinosaur forearms might have served as stabilizers that helped them steer that may not have been the case for any tail plumes.

Flightless birds such as ostriches and emus don't have big tail-feather fans and birds that do have big tail-feather fans such as peacocks

#Birds of a Feather: Whooping cranes Need Parents More Like Them Whooping cranes have made an astonishing comeback in North america thanks in part to some bizarre conservation methods.

'Long Tail Feathers The largest four-winged dinosaur known has been found and this predator has the longest feathers yet outside of birds researchers say.

This new finding yields insights on how dinosaurs may have flown the scientists added. The 125-million-year-old feathered dinosaur named Changyuraptor yangi sported feathers over its body including its arms and legs

which made it look as if it had two pairs of wings. Its fossil was unearthed in 2012 in Liaoning province in northeastern China

The fossil revealed Changyuraptor had extraordinarily long tail feathers. The tail is really the crown jewel of the specimen Chiappe said.

At about 12 inches (0. 3 m) long Changyuraptor had the longest feathers seen outside of birds.

Until now the longest known microraptorine tail feathers were only about 7 inches (0. 18 m) long Chiappe said.

The long feathers seen on both the arms and legs of four-winged dinosaurs suggest they were capable of flying.

But the scientists'aerodynamic calculations suggest Changyuraptor's long tail feathers helped slow its fall assuring safe landings.

Food Turns Feathers Pink Flamingos are large birds that are identifiable by their long necks sticklike legs and pink or reddish feathers.

The pink and reddish colors of a flamingo's feathers come from eating pigments found in algae and invertebrates.

If a flamingo were to stop eating food containing carotenoids its new feathers would begin growing in with a much paler shade

and its reddish feathers would eventually molt away. Molted feathers lose their pinkish hue. What a flamingo eats depends on

what type of beak it has. Lesser James'and Andean flamingos have what is called a deep-keeled bill.

and probably wore feathers. Anzu wylieli lived at the same time as Tyrannosaurus rex but was more lithe and graceful said study researcher Emma Schachner.

A parrot chick is born with only a thin layer of thin wispy feathers called down.

At three weeks they start to grow their adult feathers. The chick will not be matured fully for one to four years depending on its species. According to the Integrated Taxonomic Information system (ITIS) the taxonomy of parrots is:

Cockatoos have a group of feathers on top of their heads that they can move. When on full display these feathers resemble a mohawk.

The cockatoo can also retract the feathers so they lay flat against their heads r

After flying over all those nests we've gotten pretty good at quickly gauging the age of eagle chicks by evaluating size and plumage.

Facing extremes Young chicks between 9 and 23 days old were particularly vulnerable to hypothermia as they were too young to have fully grown their waterproof plumage

They have to have waterproof feathers to survive study co-author Dee Boersma told Livescience. If chicks don't have waterproof plumage they are going to die as soon as they end up in the water.

The new volcano animation reveals the plume of ash and steam rising from Sarychev. The plume appears to be capped brown ash with a head of white steam a result of air rising quickly in a strong updraft before cooling and condensing.

The plume was so immense that it cast a large shadow on the island according to NASA Earth Observatory.

See the Sarychev Eruption Animation On the ground denser gray ash known as pyroclastic flows can be seen.

Nature Newsthe water plumes erupting from the south pole of Saturn's moon Enceladus could be caused by a liquid ocean lurking many kilometres underground rather than by geysers erupting from a salty ocean just beneath the moon

The absence of sodium in the plumes pouring out of vents at Enceladus's south pole rules out geysers from water just below the surface.

or molecular sodium both in the plumes and in one of Saturn's rings thought to be fed by these plumes, the E ring.

If geysers caused Enceladus's plumes, then they would throw up salt-rich jets giving out a strong sodium signal that could be spotted by ground-based telescopes.

These grains travel out into space in the plumes along with salt-poor ice grains that are formed like snowflakes from pure water vapour.

The absence of sodium in the plume does not contradict his theory because the small amounts of sodium he would expect to see would not be detectable using the Keck telescope.

But other models exist to explain Enceladus's plumes apart from oceans or geysers. One of these suggests that reservoirs of clathrates gassy molecules locked up in the lattice of another molecule exist below the surface.

which carry up ice particles with them to form the icy plumes. These ice particles could carry up salt as well

Kieffer also says that the other gases present in the plume including methane, carbon dioxide and nitrogen can only be accounted for with the clathrate model.

Francis Nimmo, a planetary scientist at the University of California, Santa cruz, had suggested that the plumes came directly from the solid ice shell,

such as the absence of sodium in the plumes. There really ought to be some there, he says.

One reason for the difference between the EPA and the California DPR reports is that the EPA effectively assumed that no one would get hit by a'plume'of pesticide created by stagnant air pockets

Such plumes of other fumigants, she says, typically send a couple of dozen people in the United states to the emergency room every few years.

A NASA probe sent crashing into the Cabeus crater near the Moon's north pole on 9 october ploughed up a plume containing water, hydrocarbons and, unexpectedly, mercury,

it too generated subsurface oil plumes. That oil made its way around the Gulf, and at one point some beaches in Texas took an unexpected oil hit after it mixed with surface waters close to shore.

She also says that males do shed not feathers at random, and peacocks that manage to hold onto their plumes are likely to be the healthiest and fittest.

Still Petrie admits that traits such as the number of eyespots are only rough measures of tail quality,

#Evolution of plumage patterns in male and female birdsresearch published today looks at the evolutionary pathways to differences in bird plumage patterns between males

Both orders are famous not just for their flesh but also for their striking and elaborate plumages

Male and female mallards look so different that for many years they were thought to be different species. In other members of the same orders there is little apparent difference in the plumage of males and females.

and differences in plumage in almost 300 members of the Anseriformes and Galiformes orders --and focuses on patterning between male and female birds rather than colour.

The colour of plumage has attracted much research interest but the exquisite patterns of bird plumage such as the spots of the guinea fowl and the barred patterns of ducks and turkeys to just name a few have received much less attention.

Since the 1980s differences in the appearances of male and female birds have been seen through a prism of genetic correlation.

as a result of their mating patterns--they used their plumage to compete for and attract females. On the other hand female birds needed to blend into their surroundings

My research looked at the plumage patterns of male and female birds on a separate and equal basis

I reconstructed the evolutionary history of plumage pattern sexual dimorphism which allowed me to demonstrate that plumage patterns in females are not a result of genetic correlation.

Essentially what I found was that plumage patterning is remarkably labile--both male and female birds have the capacity to change between different types of patterns.

What's interesting is to consider what are the forces driving these changes in male and female plumage patterns

--whether they have an environmental basis and/or whether they have a signalling function between birds of different sexes or within the same sex.

As early as 1780 the Philosophical Transactions of the Royal Society of London published a paper by John Hunter proposing that plumage differences between the sexes were driven by sexual selection.

males of polygamous species (those with more than one mate) had developed spectacular plumage in order to attract a maximum number of females while monogamous species (those with one mate) retained similar plumage.

Gluckman said: Previous research has shown that the traditional argument that differences in plumage between the sexes stem from differences in breeding systems doesn't always hold up.

In many putatively monogamous species the plumage of the males is significantly different to that of females

and likewise males and females in many polygamous species have the same type of plumage.

This suggests that plumage is not exclusively an outcome of breeding habits --but is a matter of function in a highly complex way.

In her study of patterning Gluckman looked at the variations between the sexes of the same species and across species in order to build a picture of the pathways to similarity and differences between male and female bird plumage patterns.

She used a classification of four broad types of patterning: mottled scaled barred and spotted.

By emphasising similarities as well as differences in plumage patterns between male and female birds rather than

I found that sexual dimorphism in the plumage pattern of birds is nuanced highly and that there can be multiple types of sexual dimorphism.

In addition the plumage patterns of birds seem to transition easily between different types of dimorphism
