The first video I think is simply fantastic, it's downright inspiring actually.
The second article is interesting, I don't know if it's the same parrot as one I have heard of before with similar abilities... I actually don't find it too suprising because parrots live a long time and so have time to develop the cognitive abilities.
I might be wrong about this but you hear about animals showing interspecies affection and such, and it seams to me that the longer an animal lives the bigger the ability to do that bond seams to be. there was a recent one with a tortoise and I think it was a baby hipo or something like that. there was the lioness who adopted gazelles completely against her nature.
But that said we keep pet pigs, even though it is our nature to eat pigs.
I think it is ludicrous to believe we are the only species that has the capability to adopt within species into our lives... after all cats and dogs adopt us.
As for communication, most animals appear to have words but not syntax... so a cat would say foood food food now food... not "Can i have some food please?", but it is becoming apparent that dolphins do have syntax and parrots if it does not exist naturally are able to learn it in english. (although rarely)
The thing that truely sets us apart from animals is not the oposible thumb or technology, which is what most people say, other species can manipulate things quite well, or are able to use tools to some degree or another.... what sets us apart is written language... which gives us the abilitty to hand down knowledge and experiences through generations unmodified.
