As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Rare Purple Swamp Hen brings flocks to RSPB Minsmere in Suffolk


Calamon Común.JPGIt normally resides in the swamps of Southern Europe and Africa but has decided the lagoons of Minsmere in Suffolk are more to its liking. A 'wild' Purple Swamp Hen has never been seen in the British Isles before but it's showing itself several times a day at the RSPB reserve.

More than a thousand birdwatchers have come from across the country to see the bird, which is about the size of a chicken and looks like a fancy coloured moorhen.

Scientists Discover New Virus That Cause Beak Deformities in Birds



Aug 01, 2016 07:06 AM EDT

Scientists have discovered a new virus responsible for causing mysterious deformities in birds.

Researchers from the California Academy of Sciences, University of California San Francisco (UCSF) and the U.S. Geological Survey (USGS) have found the new virus that has been linked to Avian Keratin Disorder (AKD), a disease that causes debilitating beak overgrowth.
The disease has affected populations of wild birds around the world, and the cause has remained elusive despite decades of research.

"Take one look at a bird suffering from Avian Keratin Disorder, and you'll understand the importance of stopping its spread," Jack Dumbacher, Academy curator of ornithology and mammalogy and co-author of the study, said in a press release.

"Birds must be able to feed themselves and preen their plumage by carefully spreading waterproofing oils on their feathers. When deformed beaks restrict them from these life-giving activities, birds become cold, hungry, and often die. We're trying to understand the causes, origins, and distribution of this disorder."

Avian Keratin Disorder is characterized by severe beak deformities such as elongation, crossing or curvature. The deformities affect birds' basic behaviors such as feeding and preening, which are crucial to their survival.

The mysterious condition was first documented among a population of black-capped chickadees in south-central Alaska in the 90s and spread into Canada and the Pacific Northwest.

Gamekeepers and RSPB clash over licence to cull buzzards on shooting estate

The RSPB stands accused of hypocrisy over its opposition to the granting of a licence by Natural England to control buzzards that threaten pheasant poults on a commercial shoot.

The accusation, in a blog written by the gamekeepers’ political advisor, Charles Nodder, is that the RSPB is itself happy to use lethal control in the name of conservation of certain species and it is hypercritical of the organisation and its conservation director, Martin Harper, to complain when someone uses the same rules to protect their own interests.

In his blog on the RSPB website, Mr Harper wrote: “The thorny issue of licenses for buzzard control reappeared when Natural England issued a licence permitting the control of up to 10 buzzards to “prevent serious damage to young pheasants”.

He goes on: “The killing of a recovering British bird of prey to protect an introduced gamebird for the benefit of commercial interest is wrong. The decision sets a worrying precedent. What will be next? Red kites, peregrines, hen harriers?”

But Mr Nodder, political adviser for the National Gamekeepers’ Organisation, says buzzards are thriving and asks, if it is okay for the RSPB to be granted licences to kill even rarer birds in the name of conservation, why it is wrong for shooting estates to also apply for licences to control buzzards?

He writes: “I was particularly interested in Martin’s reaction, because there is no risk to buzzard conservation arising from Natural England’s (NE) decision whatsoever.

In law, NE cannot issue a licence if, as a result of its being carried out, the conservation status of the licensed bird would be adversely effected.

Cuckoos count cost of shortcut home, say scientists

The sound of the first cuckoo in spring is a familiar one in the British countryside.

But the summer visitor is in decline and, according to a new study, its migratory habits may be to blame.

Scientists have tagged birds leaving the UK and believe they take two different routes on their journey to spend the winter in Africa.

Surprisingly, survival is lower on the shorter route via Spain, they report in the journal, Nature Communications.

And this suggests that migration - as well as other factors such as loss of farmland and insect food - may be to blame for the cuckoo's decline.

More than half of cuckoos in the UK have been lost over the past 20 years, according to the British Trust for Ornithology (BTO) in Norfolk, which led the research.

"That pattern of starting in the same place but taking two very different routes to get there has not been seen before in any birds, to the best of our knowledge," said lead researcher Dr Chris Hewson.

"We need to understand the full annual cycle of a migratory bird in order to understand its population decline."

Why one of the world’s best fossil sites is full of severed bird feet


By Brian Switek July 20

Prehistoric creatures aren’t exactly renowned for their table manners. Most dinosaurs, for example, were incapable of chewing and had to swallow their food whole. But some ancient eaters were messier than others. And in southwestern Germany, something especially sloppy left severed bird feet strewn about a dense fossil boneyard.

The Messel Pit is one of the greatest fossil sites in the world. Within stacks of 47-million-year-old oil shale is an unmatched record of life in and around an ancient lake. There are early mammals preserved down to their fur, pairs of turtles that somehow died in the middle of mating, dozens of plant species and more than 1,000 bird skeletons. It’s the closest paleontologists can get to actually walking through a humid Eocene forest.

Not all the Messel fossils are so dazzlingly complete, though. At least eight isolated bird feet have been pulled from the same stone. They were a curiosity, but mostly overlooked as experts focused on studying and describing birds that were more intact. But now Natural History Museum paleontologist Gerald Mayr has taken another look at the feet and come up with an explanation for how they became violently separated from the rest of the avians they once belonged to.

Six New Species of Birds Have Settled in Iceland



 July 31, 2016 12:52 Updated: August 02, 2016 08:30

Six new species of birds have settled in Iceland since the turn of the century. Being a settler is not a well-defined term, but when a bird returns for nesting for 10 years or so, it seems fairly safe to say that it settled.

The six bird species are: The barnacle goose (Branta leucopsis), the shelduck (Tadorna tadorna), the eurasian woodcock (Scolopax rusticola), the blackbird (Turdus merula), the goldcrest (Regulus regulus) and finally the red crossbil (Loxia curviriostra).

According to Yann Kolbeinsson, biologist and bird enthusiast, it is a big change for a bird to decide coming to Iceland, a far-away island. Winds can play a role, and birds on their way somewhere else may stop in Iceland and decide to settle. A warmer climate might also play a role.


Flesh-eating MICE threaten to wipe out rare birds on wildlife paradise island


DEADLY flesh-eating mice are threatening to wipe out some of the world’s rarest birds on a precious wildlife paradise run by Britain.


Plagues of hungry rodents are killing up to 600,000 birds a year on one of the UK’s 30 UNESCO World Heritage Sites.

Conservationists warned today that Gough Island in the South Atlantic is in danger of losing its prestigious status – a standing that puts it on par with the Great Barrier Reef, Yellowstone National Park and the Galapagos archipelago – unless the carnivorous mice are not wiped out.

Britain has 30 World Heritage Sites, including Stonehenge, the Giant’s Causeway and Blenheim Palace as well as four overseas, but there are mounting fears for the future of Gough Island’s status because of the mice infestation.

A new report timed to coincide with the 40th World Heritage Committee meeting is revealing how the mice are causing massive breeding failure in most of the seabird colonies, including the threatened Atlantic petrel and the critically endangered Tristan albatross, now down to its last 2,000 pairs.
