and the head of a pigeon-racing club, who described a recent competition where some of the unfortunate competitors were eaten by predators

A century ago, vast flocks of passenger pigeons covered the North american skies. Hundreds of millions, even billions, stretched across the horizon in every direction.

the last known passenger pigeon, died in Cincinnati Zoo. But if Church has his way, this majestic sight could one day return to our skies.

he and other scientists are dreaming up ambitious plans to resurrect long-dead animals from pigeons to Tasmanian tigers and wooly mammoths.

 The same technologies could also prevent endangered species from going the way of the dodo oe or the passenger pigeon.

though he does not underestimate the effort required to bring the passenger pigeon back to the skies.

Armed with this code, they then need to find a way of engineering a regular pigeon's stem cells into behaving like a passenger pigeon's stem cells by mutating the genome.

Church says the complete genome of the passenger pigeon from museum specimens will soon be published and researchers are beginning to alter the genetic make-up of a more familiar bird oe the chicken oe to practice their techniques."

"What you can do for chicken you should be able to do for pigeon, and that can include creating DNA that you haven't seen alive for a 100 years,

But even if Church has the passenger pigeon's full genetic code, which he expects to recreate within a decade,

However, he admits that creating a passenger pigeon from the stem cells of an ordinary pigeon would involve a massive scale up of the same technologies.

"If there's enough people enthusiastic about bringing an extinct species like a mammoth or passenger pigeon,

His recovery was dragging until he made friends with this pigeon, and now the two are rarely apart.

and close to death until it became best friends with a pigeon. The macaque is thriving and the pair are inseparable.

Looks like I just dove into the red sea!..Rule of thumb! To be considered an expert, it helps to look grumpy!..

So how long will it be before we see a revived version of the passenger pigeon (extinct in 1914), the Tasmanian tiger (extinct in 1936),

If the technique proves successful (such as with the passenger pigeon), it might be applied to the many other extinct species that have left their#oeancient DNA#in museum specimens

chickens ducks quail geese pigeons and partridges. They sequenced the virus's genomes and the results are published Thursday (Aug 22) in the journal Nature.

The passenger pigeon the dodo and the woolly mammoth are just a few of the species wiped off the Earth by changing environments and human activities.

Reviving the passenger pigeon The passenger pigeon filled the skies of North america in flocks of millions during the 19th century.

The world's last passenger pigeon Martha died in 1914 at the Cincinnati Zoo in Ohio.

Working with Harvard biologist George Church they figured out a possible way to revive passenger pigeons.

You can't simply clone a passenger pigeon museum specimen because they no longer have fully intact genomes.

Using fragments of the passenger pigeon DNA scientists could synthesize the genes for certain traits and splice the genes together into the genome of a rock pigeon.

The cells containing the passenger pigeon DNA could be transformed into cells that produce eggs and sperm

which could be injected into rock pigeon eggs. The pigeons that hatched would be rock pigeons but their offspring would resemble passenger pigeons.

Scientists could then breed these birds and select for specific traits as a dog breeder might.

Eventually the resulting offspring would appear very much like the passenger pigeon. But that's not the only extinct animal scientists have their sights on reviving.

Woolly mammoths next? Other scientists dream of bringing back a beast that roamed the Earth hundreds of thousands of years ago:

Even if researchers succeed in creating a mammoth passenger pigeon or other extinct creature it has to survive in the wild.

For example the passenger pigeon was a very social bird known to form flocks of millions. When their numbers dwindled to a few thousand the birds stopped breeding Ehrenfeld told Livescience.

What's more the pigeons that raised them would be a different species with differing mothering techniques.

Resurrecting a creature like the passenger pigeon or woolly mammoth has a strong appeal to the public's imagination Temple said.

Ten of the positive samples were from chickens three from pigeons and seven from the surrounding environment.

For instance pigeons have also been found to be infected with the virus Huang said. To control the outbreak Chinese health officials need a way to eliminate the infected bird population

Ten years later a group of researchers and conservationists gathered in Washington D c. today (March 15) for a forum called TEDXDEEXTINCTION hosted by the National geographic Society to talk about how to revive extinct animals from the Tasmanian tiger and the saber-toothed cat to the woolly mammoth and the North american passenger pigeon.

For instance a team that includes Harvard genetics expert George Church is trying to bring back the passenger pigeon a bird that once filled eastern North america's skies.

They hope to incorporate those genes responsible for certain traits into the genome of a common rock pigeon to bring back the passenger pigeon

#A Centenary for the Last Passenger pigeon (Op-Ed) Steve Zack is coordinator of Bird Conservation for the Wildlife Conservation Society (WCS.

Monday is the centenary of the extinction of the passenger pigeon. That timing is precise because we know that the very last bird (Martha after Martha Washington) died in the Cincinnati Zoo on September 1 1914.

and stirred wonder and awe in the immensity of its flocks as did the passenger pigeon.

The passenger pigeon was likely the most abundant bird on earth in the 18th century numbering three to five billion individuals.

A ravenous wanderer Ectopistes migratorius. The wanderer that migrates. The passenger pigeon was a bird of eastern North america that moved in search of mast.

Mast is a botanical term for the hard nut fruits produced by trees like beeches and acorns.

The immense flocks of passenger pigeons were most abundant in these forests. They make waste whole forest in a short time and leave a famine behind them for most other creatures noted colonial historian Robert Beverly in 1722...

Images of Rare Passenger pigeon Museum Specimens That seems the essence of the passenger pigeon's ecology (consuming abundant mast)

and netted the passenger pigeons in great even astonishing numbers for consumption. As forests were felled

Although massive hunting events are the popular explanation for the passenger pigeon demise I side with Argentine scientist Enrique Bucher's interpretation of how the felling of the forests led to disruption of the copious masting phenomenon and the cascading decline of that once hyper-abundant bird.

Valley bottoms dominated by beeches the most important hard nut trees of the pigeons were cleared for farming.

Once abundant mast began to disappear the pigeons also lost the capacity to breed twice in a season across different masting locales.

Market hunting was eliminated by U s. Congressional legislation in the early 1900s too late for the passenger pigeon

when passenger pigeon abundance was in the many millions down from a few billions its fate was sealed.

and numerous other abundant highly social and mobile species destined to the same fate as the passenger pigeon?

The clouds that were once dense flocks of passenger pigeons remind us of the darker future for us all

Their first target is the passenger pigeon, which once was so abundant it darkened the skies of eastern North america.

If we act now we could stop yet another species going the way of the dodo.

One additional worry is that a weakening and eventual reversal in the field would disorient all those species that rely on geomagnetism for navigation including bees salmon turtles whales bacteria and pigeons.

If 1000 pigeons were bred together in a cage for 10000 years their number not being allowed to increase by chance killing then from mutual intercrossing no varieties would arise;

but if each pigeon were a self-fertilising hermaphrodite a multitude of varieties would arise.

Q. E d. If the number of 1000 pigeons were prevented increasing not by chance killing but by say all the shorter-beaked birds being killed then the whole body would come to have longer beaks.

Thirdly if 1000 pigeons were kept in a hot country and another 1000 in a cold country and fed on different food and confined in different-size aviary

I cannot even grapple with the idea even with races of dogs cattle pigeons or fowls;

Scientists at the Academy dove into their collections to discover 24 other new species that live in the world's oceans.

Working in three Chinese provinces researchers led by Yi Guan Ph d. of the University of Hong kong collected samples from the throats and digestive tracts of chickens ducks geese pigeons and quail.

Of these 20 positive samples 10 were isolated from chickens 3 from pigeons and 7 were from environmental samples.

The complete genome of three H7n9 isolates from a chicken pigeon and environmental sample was sequenced

The passenger pigeon once numbering in the billions is a strong reminder that even species considered common can become extinct without careful attention as it did Sept. 1 1914.

Bald eagles brown pelicans peregrine falcons--all species once headed the way of the passenger pigeon--are now abundant.

To prevent future extinctions like the passenger pigeon the report's authors point to science technology and knowledge as the foundation of proactive partner-driven conservation.

However similarity varied among preys in rabbits pigeons and gulls it was moderate; in squirrels and passerines it was lower

Pigeons were notably resistant to becoming infected. In additional experiments quail transmitted virus efficiently while pekin ducks and pigeons did not.

None of the poultry species became sick when infected with H7n9 making detection of the virus that much more difficult in the birds says Suarez.

Carla Dove using a comparison microscope to study feather structure in the Birds Division at the Museum of Natural history.

Dr. Carla Dove pulled out a stack of manila folders thicker than a phone book, filled with reports of bird strikes from around the world.

Dove said. The lab--the world only full-time department that studies bird strikes--was created in the 1960s, by Dove predecessor

Roxie Laybourne. Working for Laybourne, Dove was so enthusiastic about the field that she went to graduate school and studied environmental science and public policy,

with a focus on the microstructure of feathers. It didn t take her long to realize that the work performed in this little lab is a big help to the military, the aviation industry and of course, the birds.

Dove said, they can change the habitat. Not only can bird strikes threaten the safety of a flight,

The two groups have separate databases where Dove team logs each incident. Commercial airlines report strikes on a voluntary basis;

but Dove reports have included also bats, deer and â on overseas U s. military bases â animals including goats and pigs.

and mailed to Dove and her three colleagues. If we have a feather, we can take it out to the collection the 150-year-old Smithsonian bird collection,

Dove says. If it just blood or tissue, we send it to the DNA lab

Carla Dove, Nancy Rotzel and Marcy Heacker use the museum bird collection to identify birds that are involved in bird strikes.

Dove said. But that may not work at another airfield. You might have long grasses that attract mice and a bird that eats mice.

Dove and her team worked on the remains of the geese from the 2009 US AIRWAYS landing in the Hudson river.

Dove said. It like a detective story. With this incident the public became more aware of the danger that birds can pose to aviation safety.

I asked Dove, who goes birding in her spare time, what she thought about the Prospect Park geese.

typically four pounds, according to Dove. The 777 is certified for eight pounds, but only one bird, she said, not four.

but Dove isn't sure if that largely because more airfields are reporting, or because there are more strikes.

In her office, Dove has a comparison microscope, where she can put a known sample next to an unknown sample,

So what does Dove do when she boards a commercial jet? Naturally: We re always looking out the window for birds,
