Anna: There is something else. When the big man was killed, you must have wounded it. Its blood was on the leaves.

Dillon: [To Dutch.] Well, what are you gonna try next, cheese?

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.
