A native green and bronze wood pigeon with a taste for fermented fruit has been named the 2018 bird of the year in New Zealand.
The kererū is endemic to the country and can be found in both the North and South islands, living in cities as well as rural areas. Although quiet and reclusive by nature, kererū have earned a reputation as the drunkest bird in New Zealand, and been known to fall from trees after consuming rotting fruit left lying on the ground. During the summer when fruit is in abundance drunk kererū are sometimes taken to wildlife centres to sober up.
Described by conservation group Forest and Bird as “clumsy, drunk, gluttonous and glamorous,” the Kererū population is not endangered, but is vulnerable to attacks by predators such as feral cats and stoats, and also competes with possums for food.
Kererū play a vital role in dispersing the seeds of native New Zealand species such as karaka, miro, tawa and taraire across large areas, because they are one of the few birds large enough to swallow the fruit whole.
It was the clear leader in the poll, with 5,833 votes. The kākāpō came second with 3,772 and the Kakī or black stilt, an extremely rare bird that is raised by hand, coming third with 2,995 votes.

The competition, organised by Forest and Bird, is in its 14th year, and pits the country’s rare and endangered birds against one another. No bird has won twice, and this year saw the highest voter turnout on record, despite 2,000 votes being discarded after they were found to be fraudulent and originating from Australia.
More than 48,000 votes were cast this year, up from 41,000 in 2017.
Overseas celebrity endorsements from Stephen Fry for the kākāpō, and comedian Bill Bailey for the takahē upped the stakes in this year’s competition, with bird of the year also featuring on Tinder for the first time, with Shelly the kakī, or black stilt, attracting 500 matches across the country.
Although she voted for the black petrel (tāiko), prime minister Jacinda Ardern quickly offered the kererū her congratulations.
“The kererū is one of our most recognisable birds, it is often heard before it is seen,” Forest & Bird’s Megan Hubscher told Radio NZ. “It is one of our few birds that is doing OK. Only one in five of New Zealand’s native birds are increasing in number or stable, 80% are decreasing. But the kererū is doing pretty well.”
Hubscher said there were some regions of the country where kererū was not doing well – including Northland – and this was largely down to poor predator control.
However in other parts of the country where populations are thriving – such as the capital city of Wellington – road signs warn motorists to be careful because of flying kererū, which can cause serious damage because of their size and weight.
Kererū used to be hunted for their meat and feathers, but they are now protected and it is illegal to hunt them.
Some Māori tribes are given permission by the department of conservation to use the bones and feathers of kererū for cultural reasons, and reports ofthe birds being eaten for special occasions arise occasionally.
There are 168 bird species in New Zealand and about a third are threatened with extinction, with dozens more on the endangered list. Some species have dwindled to a few hundred individuals tucked away in isolated pockets of the country.

Alarm bells were sounding in the United Kingdom in October. Nope, it wasn’t another economic crisis, but a bout of the so-called “zombie pigeon” disease.#
Pigeons were making odd movements and behaving strangely. They were twisted their necks to unnatural angles, were unable to eat, wandered aimlessly around in circles… Something was happening.
Experts pointed towards the cause: paramyxovirus. The disease, while not fatal to humans, is lethal to aviary animals that contract it.
A number of pigeons had to be euthanised on the Channel island of Jersey. As of October there were no recorded cases of paramyxovirus on the British mainland.
The birds, in addition to the twisted neck, lost weight due to the physical impossibility of eating and walked in circles with clear neurological signs of the brain, as confirmed by the veterinary analyses.

What is paramyxovirus?
The British government last updated their disease guidance for paramyxovirus back in 2018. It states that the disease does not usually affect humans though does affect pigeons, as the images suggest.
Signs of paramyxovirus infection in pigeons may include:
nervous signs, including trembling wings and heads, and twisting of the neck
partial paralysis of wings and legs (birds may fall over on landing and be unable to feed)
They also became thin from not being able to eat and not being able to sit still while they produce green feces.
How can the disease spread?
The disease is spread by direct contact between pigeons and through:
pigeon transporters that have not been adequately cleaned and disinfected
drinking water in lofts and transporters
pigeon fanciers carrying infection on their clothes, hands and feet
JSPCA Animal Shelter told the Mirror that the illness has no treatment “and many birds die within a few days”.
“Any that do survive will continue to shed the virus and be a risk to other birds,” a spokesperson added. “At the JSPCA, affected birds are humanely euthanased.”
This disease cannot affect humans, but it can cause conjunctivitis in those who handle sick birds.

Researchers led by members of Oxford University’s Department of Biology have found rare colonies of the wild ancestors of common domestic and feral pigeons.
Already extinct in England and Wales, the wild Rock Dove (Columba livia) has been found on secluded Scottish and Irish islands, providing insights into how the domestic pigeon came to be.
“Feral” pigeons originate from escaped domestic birds and can be seen in towns and cities all over the world. These domestic pigeons are descended from wild Rock Doves, who nest in sea caves and mountainous areas.
Despite the success of feral pigeons, the Rock Dove has been declining throughout its global range—which once encompassed vast areas of Africa, Asia and Europe. University of Oxford DPhil student and lead author Will Smith says that “studying the decline of the Rock Dove has been challenging for researchers because of such extensive interbreeding and replacement with feral pigeons.”
Rock Doves now persist in only small, relict populations where feral pigeons have not yet been able to colonize. In fact, due to the interbreeding of feral pigeons and Rock Doves, and their resulting hybrids, many ornithologists believe that there are no truly wild Rock Doves left. However, there are potential colonies in certain places, including, in Europe, the Faroe Islands, parts of the Mediterranean and parts of Scotland and Ireland.
The researchers studied populations of birds thought to be Rock Doves in Scotland and Ireland by analyzing DNA to determine whether the birds were truly wild, and to estimate how much genetic influence from feral pigeons different wild populations had experienced.
Through a combination of expeditions and collaboration with British Trust for Ornithology bird ringers, the research team caught both feral pigeons and putative Rock Doves in places like North Uist (Uibhist a Tuath) in the Outer Hebrides, Orkney, and Cape Clear Island.
The team took feather samples from the birds for DNA analysis. By sequencing the pigeons’ DNA, they were able to show the differences between feral pigeons and Rock Doves, and also measure the degree of interbreeding between the two forms of the species.
The results confirmed that the Rock Doves of the UK and Ireland descended from the undomesticated lineage from which all feral and domestic pigeons originate, with varying degrees of interbreeding. Rock Doves in Orkney have experienced extensive interbreeding with feral pigeons and are at risk of getting hybridized to the point of their extinction as a distinct lineage. In contrast, Rock Doves in the Outer Hebrides remain almost free of feral pigeon influence.
“We identified feral pigeon ancestry in most of the Scottish and Irish Rock Dove populations we sampled, and there have been feral pigeons in Europe for hundreds of years. It was therefore really surprising to discover that the Outer Hebridean Rock Doves showed negligible signs of hybridization,” explained Will Smith.
However, feral pigeons have been reported on these islands with increasing frequency, so it might be that the distribution of wild Rock Doves in the UK continues to shrink as a result.
Recording their distribution and genetic status will help to monitor the remaining Rock Dove populations, and encourage efforts to understand potential relict populations elsewhere.
In the wider context of conservation, increasing understanding of “extinction by hybridization” will help efforts to prevent many other plants and animals, such as the Scottish wildcat, from undergoing the same fate as the Rock Dove.

A September expedition to Papua New Guinea confirmed via video the existence of the black-naped pheasant pigeon, a critically endangered species that has not been reported for 140 years.
“For much of the trip, it seemed like we had no chance of finding this bird,” said Jordan Boersma, co-leader of the expedition and a postdoctoral researcher at the Cornell Lab of Ornithology. “We were just two days away from the end of our time on Fergusson Island in Papua New Guinea when one of our remote cameras recorded the bird walking around and fanning its tail.”
The group captured the first-ever video and still photos of the bird, a large ground-dwelling species with a rust-colored back, a black head and body, and a bobbing pheasant-like tail. It may only exist far inland on Fergusson Island in hot, extremely rugged geothermal terrain laced with twisty rivers and dense with biting insects and leeches.
“After a month of searching, seeing those first photos of the pheasant pigeon felt like finding a unicorn,” said John C. Mittermeier, director of the Search for Lost Birds project at American Bird Conservancy and a core member of the expedition team. “It’s the kind of moment you dream about your entire life as a conservationist and birdwatcher.”
Almost nothing is known of the black-naped pheasant pigeon apart from two specimens collected in 1882. There are no recordings of its sounds. The researchers think it would likely sound similar to a different pheasant pigeon species on mainland Papua New Guinea—a sound locals compare to the despairing cry of a woman ostracized by her community.
Tapping into Indigenous knowledge was key to the expedition’s success. Doka Nason, a local bird expert, joined the search and advised the team on where to look. Nason set up the camera that eventually recorded the bird. “When I saw the photos, I was incredibly excited,” he said. “I was jumping around yelling, ‘We did it!'”
“It was an experience of a lifetime working with Fergusson Islanders to find the pheasant pigeon and giving talks at schools and villages about our search was a highlight,” said Jason Gregg, a co-leader of the expedition. “Kids were whispering the local name of the bird—Auwo—and everyone was talking about it. I’m so happy we know this species survives, and it opens opportunities to learn even more about the bird and its incredible home.”
But conservationists are concerned. The principal landowner where the bird was found told the search team he’d just signed a deal with a logging company—a move that could threaten the black-naped pheasant pigeon and its habitat. The team is pursuing funding so they can go back to Fergusson and try to find out how many of the species are left.
“The reason I care, why I think we should all care, is that this bird has meant something and continues to mean something to the local people,” Boersma said. “It’s part of their legends and culture. If we lose this species, then its cultural importance will be lost along with the role it plays in this fantastic ecosystem.”

Homing pigeons may share the human capacity to build on the knowledge of others, improving their navigational efficiency over time, a new Oxford University study has found.
The ability to gather, pass on and improve on knowledge over generations is known as cumulative culture. Until now humans and, arguably some other primates, were the only species thought to be capable of it.
Takao Sasaki and Dora Biro, Research Associates in the Department of Zoology at Oxford University, conducted a study testing whether homing pigeons can gradually improve their flight paths, over time. They removed and replaced individuals in pairs of birds that were given a specific navigational task. Ten chains of birds were released from the same site and generational succession was simulated with the continuous replacement of birds familiar with the route with inexperienced birds who had never flown the course before. The idea was that these individuals could then pass their experience of the route down to the next pair generation, and also enable the collective intelligence of the group to continuously improve the route’s efficiency.
The findings, published in Nature Communications, suggest that over time, the student does indeed become the teacher. The pairs’ homing performance improved consistently over generations — they streamlined their route to be more direct. Later generation groups eventually outperformed individuals that flew solo or in groups that never changed membership. Homing routes were also found to be more similar in consecutive generations of the same chain of pigeon pairs than across them, showing cross-generational knowledge transfer, or a “culture” of homing routes.
Takao Sasaki, co-author and Research Fellow in the Department of Zoology said: ‘At one stage scientists thought that only humans had the cognitive capacity to accumulate knowledge as a society. Our study shows that pigeons share these abilities with humans, at least to the extent that they are capable of improving on a behavioural solution progressively over time. Nonetheless, we do not claim that they achieve this through the same processes.’
When people share and pass knowledge down through generations, our culture tends to become more complex over time, There are many good examples of this from manufacturing and engineering. By contrast, when the process occurs between homing pigeons, the end result is an increase in the efficiency, (in this case navigational), but not necessarily the complexity, of the behaviour.
Takao Sasaki added: ‘Although they have different processes, our findings demonstrate that pigeons can accumulate knowledge and progressively improve their performance, satisfying the criteria for cumulative culture. Our results further suggest that cumulative culture does not require sophisticated cognitive abilities as previously thought.’
This study shows that collective intelligence, which typically focuses on one-time performance, can emerge from accumulation of knowledge over time.
Dora Biro, co-author and Associate Professor of Animal Behaviour concludes: ‘One key novelty, we think, is that the gradual improvement we see is not due to new ‘ideas’ about how to improve the route being introduced by individual birds. Instead, the necessary innovations in each generation come from a form of collective intelligence that arises through pairs of birds having to solve the problem together — in other words through ‘two heads being better than one’.’
Moving forward, the team intend to build on the study by investigating if a similar style of knowledge sharing and accumulation occurs in other multi-generational species’ social groups. Many animal groups have to solve the same problems repeatedly in the natural world, and if they use feedback from past outcomes of these tasks or events, this has the potential to influence, and potentially improve, the decisions the groups make in the future.
