Should NoisyNature be split?

I was re-reading Noisy Nature, and it seems to me that it's really two different (albeit related) tropes. On the one hand, it offers examples of animals being noisy when they ought to be quiet - crows cawing at night, rats always squeaking, predators growling when they should be sneaking up on prey, etc - which would be related to tropes like Roar Before Beating and With Catlike Tread, and contrasted with various stealth tropes. On the other hand, it also shoehorns in cases where an animal's Real Life sound is replaced with something inappropriate, whether out of Critical Research Failure, Rule of Cool or just convenience. That's more about Stock Sound Effects, and relates to tropes like Jungles Sound Like Kookaburras and The Coconut Effect, while having nothing whatsoever to do with whether the animal should be making a racket or not. Really, the two concepts are serving different purposes: the former audibly establishes that the animal is present a la Rule of Perception, whereas the latter is done more for atmosphere - spooky, environment-establishing, campy, whatever - than anything else.

If it's split into different tropes, Silly Animal Sound would be a subtrope of one of them.
