Hello guys, let me explain how I managed to achieve the 'Power Line Birds' achievement since it's the most complicated one.
You'll need 3 light poles (in my case, I've placed them overlapping one on top of the other). I've marked them with a black arrow and a 3. Try to align these poles with the ground of the wall (I mean the orange circle I've placed below the light pole, as you can see, it's aligned with the ground of the house) and not on the sidewalk (the sidewalk is where I've placed the orange X).
We need that wooden roof.
And finally, we need to put the wires where the birds would be. This step is the most troublesome one. I've marked on the wall where I've spawned them with a red dot, and the achievement popped for me. You can also try it on the sides and on the roof, but as I mentioned earlier, the achievement popped for me when I placed it where I marked the red dot.
