Remember he was wearing a tactical vest that hung below his belt line and an ammo belt. Makes it look a bit like his pants are black on that bridge scene but you're just seeing those two items.

1 sec before. Screenshot from one sec before. White pants visible.

I literally screenshot the vid 1 sec before that where he is wearing white pants.

Amazing shot.

Not great quality but vid of a Peregrine Falcon taking a break from hunting early in breeding season.
