In our world,
Yours, maybe, not mine. :-)
Mother Nature has returned
She was away ?
and is pleased with the spread of one of the most ubiquitous birds, the Peregrine Falcon and has granted them the intelligence capacity of a human from now on.
Where did Mother Nature put all this intelligence ?
While it's not agreed that there is a clear relationship between individual human brain size and human intelligence, it's almost certain that they'd need a brain of roughly comparable size (and function) to have comparable intelligence.
If you pack a larger brain into their existing frame (expanding the skull as needed) you're going to create a creature which is completely unbalanced. It will cease to be able to fly, probably would be barely able to move.
Where's the body to support the brain - by which I mean not just the mechanical support, but to supply it oxygen and other chemicals ? I'd be surprised if a falcon heart could pump enough blood to maintain a human sized brain or the lungs were capable of oxygenating blood quickly enough to cope with the flow required.
It's completely unrealistic.
There is now a bird that can read and can operate a computer or a kindle or whatever, can learn a rough way to communicate in bird-speak.
Operating a computer, just in mechanical terms, requires quite a lot of learning. I do not think a falcon can operate a complex device like this, and by operate I mean just not break it more often than not.
"Communicate in bird speak". With what ? It takes years to train a human to speak at all (and it's mostly nonsense even after that :-)) and humans come with the a physical mechanism designed for complex verbal communication. A falcon lacks this. I see no way for them to speak or communicate in a complex way with any kind of speech.
In one generation of the birds, with our assistance, what would be the result of this experiment?
A dying species of immobile falcon, requiring life support to just stay alive.
I'd be astonished if they could procreate because I doubt they'd live that long. So forget about generation two.
