Continuity mistake: While the team are hearing the music on the chopper, the pushed buttons on the recorder change - the third one, then the fourth, then none.
Continuity mistake: Before the team finds the crashed chopper Dutch has just a bit of camouflage on his face but after that he has more.
Continuity mistake: At the beginning while Dutch meets with Dillon the cigar in his hands disappears and reappears between shots.
Continuity mistake: The bullet riddled tree that Poncho is hiding behind changes. It goes from severely riddled to not as much damage.
Answer: In the shots where we can see what the Predator sees, sometimes when he is focusing on someone or something, we hear a kind of flash noise as he zooms in on the object. When we see the Predator's eyes flashing/glowing, that is when he is zooming in on what he's looking at.
