Mythology has attributed many supernatural features to ravens. Studies on the cognitive abilities of ravens have indeed revealed that they are exceptionally intelligent. Ravens live in complex social groups and they can gain power by building social bonds that function as alliances. Cognitive biologists of the University of Vienna now revealed that ravens use a ‘divide and rule’ strategy in dealing with the bonds of conspecifics: Socially well integrated ravens prevent others from building new alliances by breaking up their bonding attempts.

Thomas Bugnyar and his team have been studying the behavior of approximately 300 wild ravens in the Northern Austrian Alps for years. They observed that ravens slowly build alliances through affiliative interactions such as grooming and playing. However, they also observed that these affiliative interactions were…

Eurobirdwatch 2014 sees 2.5 million migrants in the air

By Elodie Cantaloube, Mon, 20/10/2014 – 08:18

On the weekend 4–5 October, over 23,000 people took part in the most exciting nature event of the autumn: the annual Eurobirdwatch. From Portugal to Kazakhstan, from Malta to Norway, BirdLife Partners invited people of all ages to discover and observe the fascinating migration of birds. The result of these two days of fun, exchange and learning was the observation of over 2.5 million birds as they migrated to southern countries in search of suitable wintering grounds.

In autumn, some species of birds, the so-called migratory birds, leave the north, where they breed in spring and summer and head to their wintering grounds in the south. The migration of several thousands of birds of different species is a unique spectacle; the BirdLife…

Big Garden Birdwatch 2014

More than half a million people are expected to be watching their garden birds the weekend (25-26 January), for the RSPB’s Big Garden Birdwatch.

It’s the biggest wildlife survey in the world and this year participants are being asked to log some of the other wildlife they see in their gardens too, including deer, squirrels, badgers, hedgehogs, frogs and toads.

Also new for 2014, is the RSPB’s LIVE bird counter, making it even easier to take part. The counter can be accessed from the RSPB website and doesn’t even need to be downloaded – simply take your laptop, tablet or smartphone to the window, enter the birds you see as you see them, while the clock counts down your hour.

Martin Harper, RSPB Conservation Director says: ”Winter has felt more like autumn for many of us and this could have a significant impact on the number of birds in our gardens.

“Birds come into gardens for food when they can’t find it in the wider countryside but if insects and berries continue to be available long into winter, numbers visiting gardens may be down. The Big Garden Birdwatch will be really interesting this year and will be a good indication of just how much the weather affects their behaviour.

“The key thing for the RSPB is that even if you feel you don’t have as many birds in your garden compared to normal, we still desperately need your results. We will be able to compare results to other mild winter years and compare regional trends, so if you don’t see many birds, we still need to know, it’s really useful information.

“The more people that take part, the greater our understanding of the threats and the solutions will be.”

Starlings hit an all time low in the 2013 Birdwatch with their numbers sinking by a further 16 per cent from 2012. Numbers of house sparrows, which are of high conservation concern, dropped by 17 percent in gardens compared to 2012, whilst numbers of bullfinches and dunnocks were down by 20 per cent and 13 per cent respectively.

The data gathered on the mammal and amphibian species will be shared with conservation partners so they can add it to their own records and will be used to help the RSPB tailor its advice on giving nature a home so people can help their wild visitors nest, feed and breed successfully.

To take part, people are asked to spend just one hour at any time of the Big Garden Birdwatch weekend noting the highest number of each bird species seen in their gardens or local outside space at anyone time. They then have three weeks to submit their results to the RSPB, either online or in the post.

Participants don’t have to actually count the other species like hedgehogs and frogs during the birdwatch hour; just tell the RSPB whether they have ever seen them in their gardens, at any time of year.

House sparrow numbers stabilise

Country Diary : Two male house sparrows

There was some good news last week when new figures from the BTO Garden BirdWatch survey revealed that the decline in house sparrow numbers appears to have levelled off.

Populations of house sparrows across the UK have fallen from about 12 million pairs in the 1970s to between 6 and 7 million pairs today, with a greater reduction in urban and rural areas than in suburban ones.

But the latest data from the British Trust for Ornithology’s (BTO) Garden BirdWatch, a citizen science survey in which birdwatchers and householders monitor gardens across the country throughout the year, suggests that the decline in gardens has stabilised since 2009.

Figures from the trust show that in 1995, the proportion of gardens reporting one or more house sparrows was about 80%. This fell steadily to 60% in 2009, and has remained at the same rate since.

“It’s too soon to say that they are increasing but the decline has definitely levelled off since 2009 and hopefully this means they’ll start to increase again,” said Clare Simm, BTO’s Garden BirdWatch development officer.

The house sparrow is a “red-listed”conservation species which has been in long-term decline, particularly in urban environments. Its populations across Britain have been hit by a loss of nesting sites and food sources, especially insects to feed their young.

In rural areas, changes in farming practices are thought to have affected house sparrows. But in urban and suburban areas the causes have been more complex, with everything from cats to air pollution and pesticides being blamed.

The BTO has recommended five simple measures for gardeners to encourage house sparrows:

• Let an area of your garden go wild to encourage insects.

• Plants like hawthorn and ivy provide thick vegetation for sparrows to hide in.

• Provide them with a home, using either a house sparrow terrace or nest boxes near the eaves of your property.

• Feed them with a suitable seed mix that includes large grains.

• Regularly clean your feeding stations to prevent disease.

UK’s endangered turtle doves given Hope!

Turtle dove

Turtle doves are one of the most endangered birds in the UK, but the population here has been given a boost by the creativity of a 6-year-old girl from Sheffield.

Operation Turtle Dove, a partnership project to save this bird on the brink of extinction, launched the competition to find names for their two logo birds. And thanks to Alice Stavert-Dobson, they are now christened as Heart and Hope.

Alice (pictured below with her sister) said: “I chose ‘Heart’ to represent love and ‘Hope’ because I hope turtle doves will still be here in the future. I was really pleased to win the competition and I can’t wait to go and see the turtle doves this summer in Pensthorpe Nature Reserve.”

Turtle doves are currently embarking on a long journey back to the UK after spending the winter in Sub-Sarahan Africa and should  arrive back in the UK around the middle of April. The threat to this iconic bird is real. Changes in modern day agricultural practices have been attributed to the loss of arable plants in farmland, which produce the early seed source turtle doves need on their return to the UK.

Alison Gardner from the RSPB said: “It is distressing to learn that we have lost nearly 60 per cent of our turtle doves in the five years to 2010.  If this decline continues we could be down to fewer than 1000 pairs by 2020, with complete UK extinction a real possibility.

“The fantastic work of Operation Turtle Dove aims to make a real difference. Project partners are working with farmers to implement a bespoke seed rich mix which will be available to turtle doves on their return in Spring. Our new turtle dove logo names reflect these birds so beautifully and we want to secure their future so children like Alice and her sister Thea will be able to enjoy their gentle ‘purring’ way into their adulthood and beyond.”

Struggle to save stricken seabirds continues

The mystery substance found on hundreds of seabirds washed up on the south coast is a “mixture of refined mineral oils”, says the Environment Agency.

Wildlife experts have warned many more birds could be affected by the waxy substance. Hundreds of birds were found on beaches from Sussex to Cornwall on Thursday. Environment Minister Richard Benyon said: “Every effort is being made to identify the cause of this problem. I’d like to thank everyone involved in helping the seabirds affected and it’s thanks to their efforts that many have been cleaned up and now have a chance of survival.”

The total rescue count so far is 162 alive and rescued, but 200 are dead, including a juvenile puffin, a fulmar and 3 razorbills. It is thought the substance may have been dumped into the English Channel by a ship. Most birds have been found in Dorset but others are appearing in Sussex, Hampshire, Devon and Cornwall.

Mistle thrushes missing from our gardens

Mistle thrushes are disappearing from UK gardens says the RSPB. The charity’s annual Big Garden Birdwatch survey – back this weekend – shows that mistle thrushes are now seen in fewer than half the number of gardens they were seen in ten years ago.

People are being urged to take part in the 34th annual Big Garden Birdwatch, on 26-27 January, to keep vital information about these, and other garden birds, coming. RSPB Conservation Director, Martin Harper, says: “Everyone that has ever taken part in Big Garden Birdwatch has helped to make us aware of huge changes in the populations of birds like house sparrows, starlings and song thrushes, leading us to do more work on the decline of these familiar birds.

“Mistle thrushes are already on the amber-list of conservation concern and are closely related to the threatened song thrush.  The rate of decline we’ve seen throughout Big Garden Birdwatch suggests these species are in need of help.”

Almost 600,000 people across the UK, including 90,000 pupils and teachers at schools, took part in the Birdwatch last year counting more than 9 million birds between them.  Everyone can join in by spending just one hour at any time over Big Garden Birdwatch weekend noting the highest number of each bird species seen in their gardens or local park at any one time then submitting the results to the RSPB.

Major seabird recovery project gets green light

manx_sr_tcm9-93537

A new 25-year partnership project that aims to protect internationally important seabird populations on the Isles of Scilly has been given the green light.

The islands are home to breeding populations of 14 species and about 20,000 birds, including storm petrels, Manx shearwaters and puffins. The local seabird population has declined by almost 25% in the past 30 years, mainly because eggs and chicks have been preyed upon by rats.

Up until now, rodent control work has been confined to Scilly’s uninhabited islands and has left them rat-free, although work is regularly required to maintain this status. The  project, which involves the RSPB, Natural England and the Duchy of Cornwall together with the islands’ Area of Outstanding  Natural Beauty partnership, Wildlife Trust and Bird Group, aims to make two of Scilly’s inhabited islands rat-free over the next 25 years.

Most of the scheme’s £900,000 financial backing is coming from the Heritage Lottery Fund and, because of Scilly’s Special Protected Area status, from the European Union’s LIFE budget too.

Paul St Pierre, RSPB Conservation Officer, said: “As well as seeking to bolster the population of seabirds, we want  to involve more people in the celebration, enjoyment and protection of the islands’ seabird heritage. We want  to help these islands make more of their seabird heritage and to strengthen  its image as a seabird-friendly destination for an ever wider audience.”
