Many people have problems with this trophy, "Flying Rats Begone!"** because when you attempt to scare away the pigeons, they always reset, making it impossible to clear them all at once. To fix that problem, Do This: First, go to **"Brink Terminal"** and grind on the top rail to access the other side. (little tip, press R2 to reach the upper rail on the ceiling)  Second, go to the top and see two pigeons on the right stairs.  Third, to scare them, go near them, and they will fly away. Do that. Four, once you scare the two pigeons from the stairs, **DON'T LOOK AWAY FOR A SECOND, KEEP THE CAMERA FOCUSED WHERE THE PIGEONS WERE AND GO DOWN THE STAIRS STILL LOOKING TOWARDS THE PLACE YOU SCARED THEM** Please look at the example in the image to get the idea.  Five, while still doing step Four, go down to the center and run Zig Zags to scare away all the pigeons(if it doesn't work, as some might come back, try and try again **while looking at the spot from step 2**  https://youtu.be/5--JTZr1Fu4?si=YL9u3wwP9h_XQuqE
