Parrot costs almost as much as copying some creature permanently, often with its superior stats, so sounds fine to me. Obviously, I voted for paying for the ability with Entropy quanta in same amount as the ability's other quanta.
Elite Parrot... I take it 1 Entropy makes you instantly target/execute the ability with no further cost? If yes, then it's fine, as it has one drawback - if you dispose of the original creature with the ability, Elite Parrot won't be mimicking it, while a Parrot will keep the copied one.
Flinches do seem costly, as Adapt can give you entirely random abilities with no possibility of choosing, and even if you get a good one it's for one turn, and you must have the quanta needed for cost, so Rainbow/EntropyLife only. I'd drop the cost a bit because of this.
