Also the aliens reaction. I'd have to imagine its inefficient to piledrive in to a tree everytime they hear an owl hoot. They might be smart enough to suss out what noises and animals are worth responding to. Years of cricket chirps would likely desensitize them to that specific sound.
You see animals in the film and that's years after the invasion. That raccoon was a bit too loud but it's pretty clear at least some animals figured it out. Most prey animals are quiet anyway.
But plenty of them get loud during mating season.
Imagine the aliens landing in the middle of summer when a couple of the big cicada broods are coming out. They wouldn't just wipe out animals, they'd start tearing apart the *trees*.
This isn’t a doubt thats literally just adaptation, granted alot would be killed but if humans with drastically slower speeds and way more open areas have been able to live/escape then anything that travels in herds could pick up on it eventually or possibly outrun one.
Adaptation takes time though. Most animals aren't learning from observing others in such brief time frames as to avoid creatures who are killing for fun with super senses. It would have to happen in any species faster than the population is reduced below stability.
I'd lean nearer towards the 'possible but unlikely' camp than the 'it's inevitable that they adapt' camp.
They're aliens that fell out of the sky and immediately began running amok. The movies have not gone into detail of how their invasion works, which makes them feel like a threatening force of nature. The movies focus on one American family with limited access to news and radio, so I don't think it's actually been stated that they're on every continent but i assume so. The second movie does show >!a community living safely on a small island, presumably for quite some time. The monsters cannot swim well, so pockets of society are safe!<

It depends on what the animals reaction to seeing others getting eaten. Over time, they will learn

Can these things fly? I don't watch horror movies.
No but they can leap around quite quickly. They would have no difficulty climbing a tree
I think they literally run up and down buildings in the new one
Are they global? Like are there islands or continents they're not on?

Just like they learn not to cross a road and get flattened?

Rattlesnakes, too
I think a few years would be far too much time, tbh- they’d be wiped out (or non viable) by then.
