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.
According to their analysis domestic ducks and chickens played distinct roles in the genesis of the H7n9 virus infecting humans today.
Within ducks and later within chickens various strains of avian H7n9 H7n7 and H9n2 influenza exchanged genes with one another in different combinations.
Environmental samples from poultry cages water at two local poultry markets and swans from the residential area were tested also.

and to connect a breeding population of Asian great bustards to their wintering grounds. The research also offers insight into conservation challenges.
Mimi Kessler a doctoral candidate in biology at the School of Life sciences has spent more than two years on Eurasian grasslands studying habitat use population genetics causes of mortality and migration routes of the Asian great bustards.
Great bustards are large birds found in grasslands from Spain to Mongolia. Males of the Asian subspecies can weigh up to 35 pounds
The significant size difference between males and females makes bustards the most sexually dimorphic avian species On earth.
and wariness toward humans Asian bustards are seen rarely with the naked eye. Kessler and her colleagues use spotting-scopes on hillsides to scan valleys in Mongolia
Members of our team often dream about capturing a bustard. And when it does finally happen it's a real adrenaline rush.
Kessler says great bustards across Eurasia exhibit a range of migratory behavior corresponding to the severity of winter weather.
Great bustards found in Spain may travel only about 10 miles annually whereas those in western Russia travel about 600 miles one way to warmer wintering regions.
The Asian subspecies however is the marathon runner of the great bustard family. In Mongolia winter temperatures can drop 30 to 50 degrees below zero Kessler says.
We found that the Asian great bustards travel for an average of two months covering 1200 miles to reach wintering grounds in Shaanxi province in central China.
since research regarding Asian great bustards is scarce but also offer an insight into the challenges the Asian bustard subspecies and conservationists face.
Asian great bustards are threatened a species in Mongolia Kessler says. They face several dangers including poaching for sport or sale of meat to exotic food markets in China.
The birds have a low reproductive rate; adults raise just one or two chicks to maturity every 10 years making hunting unsustainable.
Bustards are also less maneuverable due to their large size which makes collisions with power lines and overhead cables a serious threat.
Pesticides kill protein-rich insects that bustard chicks rely on for rapid growth to be able to migrate come fall.
We want our work to lead to a brighter future for local communities and these unique populations of great bustards.
These unique grasslands are home to many threatened birds including by far the largest remaining population of the critically endangered Bengal florican--the world's rarest bustard.
Other birds under threat in this area include sarus cranes storks ibises and eagles. Rural communities have been left vulnerable to land-grabbing and privatisation of-communal grasslands.

#Captive whooping cranes released into the wildfour whooping crane chicks raised in captivity began their integration into the wild Saturday as part of the continuing effort to increase the wild population of this endangered species. The cranes hatched
The parent-reared whooping crane chicks were hatched and raised by captive adult whooping cranes. This method relies entirely on the expertise of captive parents who care for exercise
and feed the chicks. These chicks will join a flock of about 95 cranes that inhabit wetlands on the refuge and elsewhere in central Wisconsin during the spring and summer.
in order to establish a migratory flock of whooping cranes in the eastern United states. The Eastern Migratory Flock flies south to wetlands in the Southeast United states for the winter.
Over the past 13 years USGS biologists--dressed in costumes to avoid having the birds imprint on people--have raised between five and 20 whooping crane chicks annually that have been released into the Eastern Migratory Flock said John French leader of the USGS whooping crane
and whooping cranes in Florida this is only the second year it has been attempted with a migratory population.

while they acclimated to their new surroundings near other free-ranging whooping cranes. The pens are located in the vicinity of pairs of adult whooping cranes without chicks of their own.
Such pairs have a tendency to adopt other chicks and when adopted will lead them south during migration
In addition to the four parent-reared chicks released at Necedah NWR seven costumed-reared whooping crane chicks will join the eastern migratory flock this year as well.
All of the releases of whooping cranes in Wisconsin add to the Eastern Migratory Flock a reintroduction project undertaken by a broad coalition of Federal state

#Colonization of Brazil by the cattle egretin recent years the cattle egret (Bubulcus ibis) has colonized American continent.
A new study of the colonization patterns of the cattle egret in Brazil published in the open access journal Neobiota offers a new take on the study of alien species. The cattle egret primarily inhabits grassland habitats and forages in close
The populations of cattle egret in Brazil are alien to the region but unlike a number of bird species that have been introduced to nonnative areas through human intervention the cattle egret is known to have established
and expanded to The americas without such intervention. The first sightings in the New world were reported for Suriname between 1877 and 1882 in the North of South america followed by sightings in British guiana and Colombia and subsequent expansion throughout The americas.
In Brazil the cattle egret was recorded first in the northern region of the country in 1964 feeding along with buffalos on Marajo Island in the state of Para.
While the cattle egret is not currently a threat to native fauna in Brazil throughout most of its geographic distribution it has the potential to produce adverse effects as evidenced by its occupation of island environments.
For example in the Fernando de Noronha archipelago the cattle egret drives adult native seabirds away from their nests in breeding colonies
Understanding how the cattle egret colonized Brazil is crucial for the better understanding of dispersal patterns of bird populations
and their interaction with the local species. Explaining the colonization of The americas by the cattle egret is a challenging task due to the lack of sufficient information and reports on entrance time locality and number of events.
