THE CROWS’ FEAT
Birds put to work clearing up rubbish at theme park
The historical theme park Hungry bird lands on a bin Villiers added the birds “like to communicate with humans and establish a relationship through play”.
The popular attraction, Puy du Fou, in Les Epesses in the Pays de la Loire region of western France, is reckoned to be the country’s second most popular theme park after Disneyland Paris.
Scientists say crows are surprisingly intelligent and are capable of using tools, solving complex problems and remembering human faces.
Naturalist and broadcaster Chris Packham described a crow’s brain power as “remarkable” during his TV series Inside the Animal Mind.
After the bird completed a tricky eight-part test, Chris said he had “never seen anything like it”. He added: “I have observed a lot of bird behaviour and I can hardly believe it.”
Evidence like this has led to experiments to see if crows can be trained to do work, such as picking up litter, and now it seems they can. Some crows have been seen in the wild using sticks in their beaks like spades to extract insects from logs.
Crows in the US have devised a way of getting into hard-shelled nuts by dropping them on busy crossroads where they are cracked by passing cars. Crow locates some litter The birds then grab the cracked nuts when motors are stopped at red lights.
These aren’t the only feathered creatures who have amazed experts.
Australian magpies can understand what other types of birds are saying. Research this year found the animals have learned the meanings of different calls by the noisy miner and eavesdrop on them to find out which predators are near.
Macaws use ropes to fetch items that would normally be difficult to reach, and some herons use bait to catch fish.
