Interesting, but not very surprising. A very small percentage of people come up with genuinely new ideas. A slightly larger percentage synthesize those ideas into other ideas. About half the remaining can learn those ideas, and the other half stares into the abyss of natural selection.

Interesting that the other parrot learnt by copying the first parrot, not buy independently coming up with the idea itself.

Thankfully the parrot was able to just copy and adapt without worrying abou IP laws :P
I'm imagining some magpie with a tie flying in, taking the stick and demanding a nut to give it back :D
Big evolutionary advantage in being able to transfer newfound skills through observation and copying.
