Study: Ravens communicate better than most of animal kingdom
Wild ravens in the Austrian alps have been observed using their beaks and body language to direct another raven’s attention to a specific object, marking the first time such complex gesturing has been documented in an animal outside of humans and their primate cousins.

Can crows read?
Crows can recognise and ascribe numerical meaning to symbols, a new study shows, suggesting that the unusually intelligent birds may be able to “read” numbers and simple icons.

In Connecticut, A Return Of The Raven
n the nest were three baby ravens, born this spring practically within the shadow of Hartford skyscrapers, a figurative exclamation point to the dramatic resurgence of the common raven in Connecticut, a bird that was anything but common for the past two centuries.
Crows are one of the world’s smartest birds
This party has some uninvited guests - the ravens and the house crows. In the gathering, a Langa singer is singing a song, which talks about the wait for her lover addressed to the crows. The song says you can eat the rest of my body but leave my eyes, so that I can see my lover, when he returns.

Brainy Birds Live the High Life in Cities
The brainier a bird is, the better its chances are of thriving in a city, according to a new study that found many big-brained birds can succeed in urban environments.
Studying The Common Raven In Maine (audio)
An interest in ravens led John and Colleen Marzluff to a frozen cabin in western Maine to conduct the first extensive study on the common raven's winter ecology. What did they discover in the frozen north, surrounded by sled dogs and ravens? We'll find out today.
'Dog Days, Raven Nights': John and Colleen Marzluff chronicle the complicated world of ravens
John and Colleen Marzluff's new book, "Dog Days, Raven Nights," is a fascinating account of their four years spent trying to determine why ravens do what they do. The authors will discuss their book Tuesday at Town Hall Seattle.
US military planned using spy crows to find Osama bin Laden (video)
The United States military funded research into using networks of 'spy crows' to locate soldiers who are missing in action, and extended the work to see if the birds might be useful in helping them to find Osama bin Laden. The idea may seem far-fetched, but unlike some military research programs (such as the Stargate remote-viewing program) it is actually based on sound science.
Scots landowners call for licence to kill birds of prey
Every year up to 30 protected birds are found dead, including rare species such as Golden Eagles and Hen Harriers. Existing powers allow ministers to sign off on the killing of some birds of prey by sporting estates, but the powers have never been used. Now landowners want to be granted licenses that would allow the targeted cull of more common species such as Buzzards and Ravens.
Rats threatening Haida Gwaii targeted for eradication
Whenever rodents are targeted, other animals could also be poisoned, as was the case when the Canadian Wildlife Service took aim at Norway rats on Haida Gwaii’s Langara Island in 1995. Several ravens broke into the poisonous bait stations, while others died after consuming dead rats. Bald eagles were also affected. A 1997 study by Mr. Howald showed about 15 per cent of Langara’s bald eagle population was inadvertently exposed to rodenticide, likely as a result of eating ravens. However, none of the eagles died.
Farewell to Mice on the Farallon Islands? An Eradication Plan, to Save Storm-petrels
Similar rodent removal projects have taken place successfully at 320 islands worldwide. It wouldn’t affect the seabirds, and there aren’t any other mammals on the islands; but it could have an adverse effect on burrowing owls, crows, and ravens, which worries some. So the plan’s currently up for debate.

The researchers want to know why it is that, of the 700 or so species of crows, ravens, rooks, jays and magpies that make up the world’s generally clever panoply of corvids, the New Caledonian crow became such an outlier, an avian savant, a YouTube top of the line.
“It’s a big puzzle,” said Russell D. Gray, head of the Auckland lab. “Why them? Why is this species on a small island in the Pacific able to not just use but to manufacture a variety of tools, and in a flexible rather than a rote or programmatic way? Why are they able to do at least as well as chimpanzees on experiments of cognition that show an understanding of the physical properties of the world and an ability to generalize from one problem to the next?”

Knud Jønsson, now at the Natural History Museum of Denmark in Copenhagen, set out to unravel the history of crows for his doctoral dissertation. By building a family tree of the world's corvids based on comparisons of DNA sequences and anatomy, and their present geographic distribution, he traced their origins to New Guinea, several hundred kilometres north of Australia, about 30 million years ago.

Lead in ravens drops with copper bullets
Hunters who shot copper bullets instead of lead ones during hunts on the National Elk Refuge and in Grand Teton National Park likely helped reduce blood lead levels in Jackson Hole’s ravens, scientists say.

What do Van Gogh, Shakespeare, the Hopi and Kayukon People, Mark Twain, and the rock band The Counting Crows have in common? They all draw inspiration from some of our most common, but least understood birds: the crow and the raven. Dr. John Marzluff, Professor of Wildlife Science at the University of Washington, leads us on an investigation of the inspiration of ravens on people and our effects on these adaptable birds.
