Gift Of The Crow

We have been feeding a small family of four ravens (paired pair and their two year old chicks) for years.
They left these gifts, ears of corn coiled on pine boughs, two days in a row last week. It's not just generous, it's creative, it's art. My mind is blown. pic.twitter.com/tT5ORZ3AHL Stuart Dahlquist fed a family of American crows in his backyard for more than four years before the crows gave him anything in return.
At least according to him. On a recent March morning, Dahlquist walked out of his northeast Seattle home and noticed a short pine branch with a soda slab on the end. It was placed right next to his back door, exactly where he leaves the dry cat food every day.

The next day he found a second branch identical to the first in the same place. He and his wife toured the area, but found no other explanation for the strange objects. The crows, they reasoned, must have wrapped the notes in the pine tree and left them for their human benefactors to find.

Dahlquist, a musician and handyman who runs a pet door installation business, shared a photo of the twigs on Twitter. "It's not just generous, it's creative, it's art," he wrote. It went viral with over 9,000 retweets and 33,000 likes. But is it really possible that the crows created these objects and left them with Dahlquist on purpose?
It was definitely not behavior I'd ever seen before," says Kaeli Swift, an animal behaviorist who studies corvids at the University of Washington. "But I wouldn't necessarily be surprised if she makes a crow." Crows, as members of the corvid family, are highly intelligent creatures that make tools, recognize individuals, and learn from each other.
Wild crows are not known to make or display art. But sometimes they leave items like keys, lost earrings, bones, or stones for the people who feed them, which John Marzluff, a conservation ecologist and Swift's colleague at the University of Washington, calls a "gift."
“Cawfee” Mug
Marzluff first learned of the gift in the early 2000s, when he was collecting stories for a new book on raven intelligence. A man who for years fed crows in his backyard told Marzluff that one day he found a candy heart on his bird feeder.
Though skeptical at first, Marzluff could find no reasonable explanation for the heart's appearance other than that the crow had left it there. Not everyone who feeds crows gets strange items, but there's enough anecdotal evidence that Marzluff has no doubt it happens. The behavior hasn't been studied extensively, but limited evidence suggests that corvids behave differently among the humans they know.

For example, a 2014 study by the Konrad Lorenz Institute in Austria found that ravens and ravens were more motivated to trade items with human experimenters they knew rather than those they didn't. But scientists don't know why birds leave these items behind. "There's always this tipping point in animal behavior -- intention -- because we can't ask them about it," says Jennifer Campbell-Smith, a behavioral ecologist who earned her PhD from Binghamton University studying crows.
People quickly assume that crows leave items in gratitude. After all, people often find "gifts" in which they feed corvids, indicating some kind of reciprocity. But when we take on gratitude, we project human emotion onto animals, Swift says. Rather, the gift-giving behavior can easily turn into an accident, she says.

Curious crows often fly off with an object, then lose interest and leave it behind. If the crow accidentally leaves an object that people put food into, people might get excited and hand out more food. The raven learns that leaving random items behind means a bigger meal, and can teach the rest of the raven family to do the same.
If you've ever trained a dog, you know that food is a wonderful motivator for reinforcing behavior," says Swift. If they could create a "gift" by intentionally tying metal cans to branches, this behavior would go a step beyond what these scientists had previously experienced.
But Marzluff and Campbell-Smith would not rule out that Dahlquist's crows produced the soda-eared twigs. "I'm very skeptical of random internet sources, but knowing these birds and how intelligent they are, I wouldn't be shocked," says Campbell-Smith. We may not know why crows do what they do, but that doesn't make these creatures any less fascinating, Swift says.

“It's still an amazing example of how crows are really watching us and watching and extracting data in their own way to best manipulate us,” she says. Dahlquist, for his part, plans to continue feeding the crows and is considering getting a pine bough tattoo.

Great stories about raven behavior and how it compares to our behavior. I've left out some rough details about corvid brain structures. Baca menjaan lengkap This was quite disappointing. Quite a few anecdotes, none of them surprising if you've read the news about crows. Very little has been written about the study of the intelligence of ravens.
