Which is cool, but sucks if their new technique is used to get _your_ food.
One year there was a group of kea who would effectively mug solo hikers who'd set up camp. They'd break into your tent and/or backpack by undoing the zips, and would use decoy kea to distract you while doing so (a group of parrots pulling out your tent pegs or removing your bootlaces is very distracting indeed.)
And at a popular photo stop [1], they have their routine for fleecing tourists down pat - a couple of kea will cavort charmingly to get your attention, and when you start taking photos, their accomplices will then try to access your bag, or even your car if you left the door open...

In humans at least we know that if an individual doesn't pick up a language as a child they will not be fully able to as an adult, and will have cognitive disabilities as a result. A modern example we had to read about in my neuroscience undergraduate program was Genie. When rescued from an abusive upbringing she was able to learn some nonverbal communication over the span of months, but missing that critical development period in childhood had lifelong impacts. https://en.wikipedia.org/wiki/Genie_(feral_child)
Similarly, if someone can “speak/think” in Lisp - they will be able to solve a lot of problems that someone who can only “speak/think” in Bash cannot.
