Question

He peers at you from one of the higher perches. voice change

Answer 1

You are being peered by him from one of the higher perches.
Our subject is He
Our object is at you
"from one of the higher perches" is just to make the given sentence lengthy
You have to keep the subject and object interlaced. And change the verb accordingly...

Answer 2

The given sentence is active 

Here he is subject 

We have to make high percehes the subject to make it passive (vvoice change)

So the sentence would look like

From one of the higher perches , he peers at you

Or you are being peered by him from one of the higher perches

If we make you the subject

Both are correct
