Mockingbirds can place your face

Mockingbirds can quickly recognise individual humans who seem to be a threat to their nest. After only a short time, the birds recognise someone who has bothered them and make big efforts to drive them away. But they ignore other passers-by or nearby strangers.

This research took place at the University of Florida, where Professor Doug Levey, a zoologist, is reported as saying:

Mockingbirds can quickly learn to recognise individuals

“We don’t know whether it’s unique to mockingbirds, but it does suggest these birds are a heck of a lot more intelligent than people have ever given them credit for. People have known for a long time that crows and parrots for example have a lot of intelligence. But these birds are fairly small. … It’ll change the way people view the intelligence of birds like this.”
The mockingbirds live in what is considered to be a natural environment, and researchers say their scientific paper will be the first published research to show that “wild animals living in their natural settings recognize individuals of other species.”

These clever birds show us yet again that we need to respect animals’ abilities when human actions affect their lives.

Clever Karta: Orang-utan with a mission

Karta, a 27-year old orang-utan, escaped from her zoo enclosure by twisting the wires in the electric fence with a stick, making them short-circuit.

According to Sky News, clever Karta then “piled up debris to help her climb over a concrete and glass wall.”

Karta took herself back to the enclosure after an hour. The zoo curator says that Karta is ”ingenious”, and that she watches the day to day activities of zoo staff with interest – probably to see what she can learn!

Many animals, including great apes, pigs and elephants, have developed intelligence to obtain a living from their complex environments. Orang-utans in nature live in the Indonesian rainforest, one of the most biodiverse environments in the world.

Lives of Animals.org has some concerns with the comment in this clip that Karta’s enclosure will be “pruned.” While increased security may be wanted, restricting Karta’s environment is unlikely to be the best outcome for her. While the zoo has clearly attempted to provide an interesting enclosure for Karta, perhaps her escape attempt tells us that all is not well with her world. We have to ask to what extent is it possible to provide for the needs of complex, wide-ranging animals in captivity?

Never underestimate an orang-utan
There’s a anecdote often told about great apes and if you know its origins, please let us know.

Don't underestimate us

Don't underestimate us

If you give a screwdriver to a gorilla, he will look at it briefly and then discard it.
If you give the screwdriver to a chimp, he’ll think of a hundred uses for it.
If you give the screwdriver to an orang-utan, he’ll pretend to ignore it until you’ve gone, when he will let himself of the cage with it…

Cockatoon!

Snowball, a cockatoo who lives at a bird rescue centre, seems to love to dance. This clip shows us that Snowball can keep time as well as many humans!

Scientists looked at YouTube videos to see which animals could do this. Alex the African Grey parrot was famous for his abilities to count and to distinguish between colours and shapes – and he could also keep the beat. In fact, the video search found that 14 different species of parrot who kept time to music.


The scientists said: “Our analyses showed that these birds’ movements were more lined up with the musical beat than we’d expect by chance. … We found strong evidence that they were synchronizing with the beat, something that has not been seen before in other species.”


They suggest that the parts of the brain used for copying sounds are also involved in this ability to keep in time with the beat.

Better conditions for pigs

It is well known that pigs are intelligent and curious.  In nature, sows make a secure nest for their piglets and there are strong bonds between mother and young.

Recent research with pigs found that they have “episodic-like memory” – a particular kind of memory which indicates highly developed mental abilities.

Despite our knowledge of their sentience, the majority of the world’s pigs are kept in factory farms. And if the animal welfare reasons are not enough to end factory farming, swine flu may give us another reason. Cramped, stressed animals in filthy conditions provide the ideal breeding ground for bugs. (The link takes you to a short clip on CNN News with disease expert Dr Michael Greger).

High welfare, free range or preferably organic systems can provide a much better life for pigs. Let’s give them space, fresh air and a life worth living.
