#Huge owls need huge treesa study spearheaded by the Wildlife Conservation Society and the University of Minnesota has shown that the world's largest owl
--and one of the rarest--is also a key indicator of the health of some of the last great primary forests of Russia's Far east.
The study found that Blakiston's fish owl relies on old-growth forests along streams for both breeding
and nesting characteristics of Blakiston's fish owl in Primorye Russia where they looked at nesting habitat over 20213 square kilometers (7804 square miles).
because they are central to the owls'nesting and foraging behavior. Moreover conservation of Primorye's forests and rivers sustains habitat for many other species:
some of the 12 other owl species found in Primorye; and mammals like the endangered Amur (or Siberian) tiger Asiatic black bear and wild boar.
Listed as Endangered by IUCN Blakiston's fish owl is restricted to riparian areas in Russia China Japan and possibly North korea.
Blakiston's fish owl is a clear indicator of the health of the forests rivers

#Genomes of peregrine and saker falcons throw lights on evolution of a predatory lifestylein a collaborative study published online in Nature Genetics researchers from Cardiff University BGI International Wildlife Consultants Ltd
. and Abu dhabi Falcon Hospital have completed the genome sequencing and analysis of two iconic falcons the peregrine (Falco peregrinus) and saker (Falco cherrug).
The work provides an invaluable resource for the deep understanding of the adaptive evolution in raptors and the genetic basis of their wide distribution.
Peregrine and saker falcons are widespread and their unique morphological physiological and behavioral adaptations make them successful hunters.
The peregrine is renowned as the world's fastest animal and the falcon is the national emblem of United Arab Emirate.
In recent decades peregrine and saker falcons have been listed as endangered due to rapid population declines caused by a wide range of factors including environmental change overharvesting for falconry habitat loss and bioaccumulation of pesticides (e g.
DDT PCBS. In this study researchers focused on the evolutionary basis of predatory adaptations underlying peregrine and saker.
They conducted whole genome sequencing and assembled the high quality 1. 2 Gb reference genomes for each falcon species. Phylogenic analysis suggested that the two falcon species might diverged 2. 1 million years ago.
Comparing with chicken and zebra finch researchers found the transposable element composition of falcons was most similar to that of zebra finch.
Large segmental duplications in falcons are less frequent than that in chicken and zebra finch and comprise less than 1%of both falcon genomes.
They also found that a gene expansion in the olfactory receptor Î-c clade in chicken
and zebra finch is not present in falcons possibly reflecting their reliance on vision for locating prey.
Observing genome-wide rapid evolution for both falcons chicken zebra finch and turkey researchers found that the nervous system olfaction
and sodium ion transport have evolved rapidly in falcons and also the evolutionary novelties in beak development related genes of falcons and saker-unique arid-adaptation related genes.
Shengkai Pan bioinformatics expert from BGI said The two falcon genomes are the first predatory bird genome published.
The data presented in this study will advance our understanding of the adaptive evolution of raptors as well as aid the conservation of endangered falcon species. Story Source:

#Vultures foraging far and wide face a poisonous futurea first ever study of the range and habits of white-backed vultures across southern Africa shows that they often shun national parks preferring to forage further afield on private farmland.
This behaviour and their tendency to scavenge in groups means that vultures risk encountering dead cattle that have been administered veterinary drugs that are poisonous to them
or even poisoned carcasses intended to control other carnivores such as jackals. The research using Global Positioning System (GPS) satellite transmitters to track the movements of adolescent vultures is published in the journal PLOS ONE.
The white-backed vulture is a widespread but declining species in Africa and it is listed now as endangered.
In India several vulture species are on the verge of extinction due to accidental poisoning from cattle carcasses that contain anti-inflammatory drugs administered by farmers.
These drugs are nonlethal to cattle yet fatal to vultures. There is a concern that these drugs could become more widely used in Africa.
Vultures prefer to feed in savannah grassland habitats and away from other competing carnivores such as lions and the new study shows that the birds will go to considerable lengths to find food crossing multiple state boundaries with each bird on average ranging across an area twice the size of England.
Co-lead author Dr Stephen Willis School of Biological and Biomedical sciences Durham University said: We found that young vultures travel much further than we ever imagined to find food sometimes moving more than 220 kilometres a day.
Individuals moved through up to five countries over a period of 200 days emphasising the need for conservation collaboration among countries to protect this species. In South africa the vultures avoided the national parks that have been established to conserve wildlife.
As a result these parks are unlikely to protect such a wide-ranging species against threats in the wider landscape.
The vultures may actively avoid parks with numerous large mammal predators due to competition for food
We found evidence that individual birds were attracted to'vulture restaurants'where carrion is regularly put out as an extra source of food for vultures
Such'restaurants'could be used in future to attract vultures to areas away from sites where they are at high risk of poisoning.
The team tracked six immature African white-backed vultures (Gyps africanus: five for 200 days and one for 101 days) across southern Africa using GPS tracking units
Modern farming practices mean that vultures face an increasing risk of fatal poisoning. The provision of an uncontaminated supply of food research into veterinary practices and education for farmers could all be part of a future solution
if vulture numbers continue to plummet. Story Source: The above story is provided based on materials by Durham University.

hen harrier conservation on UK moorlandsas another grouse shooting season begins research out today in The british Ecological Society's Journal of Applied Ecology shows ecology could help break the decades-long deadlock
and conservationists seeking to protect hen harriers on UK moorlands. Led by Professor Steve Redpath of the University of Aberdeen the study involved grouse managers and conservationists as well as ecologists.
The model showed that at certain population densities harriers can coexist with profitable grouse shooting.
The model suggested that across the grouse moors of England there was room for 70 pairs of hen harriers at relatively low cost for grouse shooting.
when harriers breed at levels that have a significant economic impact on grouse shoots the excess chicks would be removed from the grouse moors reared in captivity
Similar schemes are used in continental Europe where harriers breeding in crops are threatened by harvesting. The next step is for grouse managers
and conservationists to use the results of the model to agree on an acceptable number of harriers
The standoff between grouse managers and hen harrier conservationists is one of the UK's most bitter and contentious wildlife conflicts.
and see any predation by hen harriers as a threat. Hen harriers eat grouse and are killed illegally so
despite being protected legally the birds have disappeared all but on moorland managed for intensive grouse shooting. There were no breeding harriers in England in 2013.
Grouse moor management has benefits for biodiversity and for communities. The question however remains as to how the illegal killing can be stopped without losing these benefits.
and three raptor species commonly found in sagebrush ecosystems: Red-tailed hawks Swainson's Hawks and Ferruginous Hawks.
Using the data from their field research and reviewing historical data from other studies the scientists developed models to predict nesting probabilities for each species. Overall the analysis showed that transmission towers

and 87.1 percent more likely to be that of a raven than that of a Swainson's Hawk Red-tailed hawk and Ferruginous Hawk respectively.
whereas some species of raptors like the Ferruginous Hawk have been impacted and limited in nesting areas said study lead author Peter Coates an ecologist with the USGS Western Ecological Research center.
Why the difference in nest selection between ravens and large hawks? The answer may be linked to the availability of preferred prey.
Conversely hawks tend to be strongly territorial intolerant of human disturbance and prefer prey like jackrabbits that occupy similar habitats said coauthor
Since ravens are important predators of young birds and eggs and hawks are predominantly predators of adults these landscape changes could shift ecosystem dynamics.
Predation risk would now likely be greater for sage-grouse eggs and young and correspondingly lower for adult sage-grouse and other prey species. This adds new insights for ecosystem managers who seek to understand the complex relationships between ravens hawks sage-grouse populations and habitat changes.

#Tests confirm that beloved hawk succumbed to multiple rat poisonsa red-tailed hawk named Ruby captured the imagination of many Massachusetts residents who watched Ruby
and that we hope will protect future generations of raptors from dying needlessly from rodenticide poisoning.
The study examined four species of birds (red-tailed hawks barred owls eastern screech owls and great horned owls) and found that of those that tested positive 99 percent had residues of the SGAR brodifacoum.
Second-generation anticoagulant rodenticides are more potent than their first-generation cousins. Rodents and other species need a much smaller amount of the poisons to suffer their effects.
For example a red-tailed hawk that repeatedly feeds on prey containing sublethal amounts of the second-generation poison is at risk for accumulating a lethal amount over time.

#Drought and drowning equal vulture supermarketafrican vultures are famous for quickly finding carcasses; so much so that they are considered clairvoyants in parts of Africa.
But just how do vultures know where to find food across vast regions in the first place? In a paper appearing in the January 8th edition of the journal PLOS ONE Dr. Corinne Kendall of Columbia University
and African Vulture Technical Advisor with the Wildlife Conservation Society (WCS) and colleagues have discovered that vultures rather than aggregating where animals are most abundant as previously thought
For decades scientists have assumed that vultures would follow the largest food source available. In the case of the Mara-Serengeti ecosystem this would be the migratory wildebeest herds
Instead this study found that two of the three species of vultures studied preferentially selected areas of low rainfall
Data were collected from GSM-GPS telemetry devices attached to three species of vultures in Mara-Serengeti ecosystem of East Africa.
The data revealed that vultures focused on the immense wildebeest herds only during the dry season
Our study shows that vultures seek out areas not where wildlife are most abundant but where they are most likely to die said lead author Corinne Kendall.
This shows that for vultures prey mortality is more important than prey abundance. The researchers found that for the rest of the year vultures travel enormous distances in search of food.
Kendall said: What has surprised really us is what the vultures do the rest of the year.
From November to June the vultures travel all over Kenya and Northern Tanzania with some individuals using an area of more than 200000 square kilometers (77000 square miles)--that's a region larger than New jersey
and New york state combined or roughly the size of the entire United kingdom. As one of the only obligate scavengers in the animal kingdom vultures are adapted specially to feed on dead animals or carcasses.
Keith Bildstein Director of Conservation Science at Hawk Mountain Sanctuary and a study co-author said:
We knew that vultures use efficient soaring flight keen eyesight and even used information from each other to find food
but we had a poor sense of how they decide where to search on a landscape scale.
White-backed vultures and Ruppell's vultures two of the species studied have been listed up to Endangered status by the IUCN due to dramatic declines seen throughout the African continent.
Munir Virani Director of Africa programs for the Peregrine Fund and co-author of the study said:
Because the vultures spend so much time outside of protected areas they are extremely susceptible to poisoning
and other diseases is now the focus of a new effort by the Wildlife Conservation Society the Peregrine Fund and Hawk Mountain Sanctuary.
and others in shaping a conservation effort to revive vulture populations while eliminating the poisoning said:
This information is critical to understanding the scale of effort needed to protect vulture species in East Africa.
This work was done in collaboration with Dr. Virani of The Peregrine Fund Dr. Hopcraft of Frankfurt Zoological Society Dr. Bildstein of Hawk Mountain Sanctuary and Dr. Rubenstein of Princeton university.
