Parrots imitate mob sounds

So I was goofing off in 1.14.1 to get myself used to the new items and such. I was around an empty pillager outpost, at that time spawning a few pillagers manually to pin down a duo of wandering traders who were passing by.

After the traders and their llamas had been exterminated, I decided to lighten up the mood by placing a few parrots on the rooftop by egg.

Lo and behold, the parrots began making their usual rumpus of squawks, shrieks and the like. But pillager sounds, high-pitched as a baby villager's might be, began playing along with the parrot sounds. There were a few pillagers on the ground, but the sounds were clearly coming from the parrots.

It's not serious, but I'd like it fixed soon.
