Pitch Black: They’re all dead (HD CLIP)

What’s happening in this Pitch Black movie clip? While others try to rationalize, Fry doubts, and Riddick states baldly that the former occupants are all dead, and by the same creatures who killed Zeke (John Moore). All this while Ali (Firass Dirani from The Combination) is still in the nearly dark Coring room, which unfortunately has Alien birds nesting near its ceiling. Riddick had unknowingly uncovered the solar equipment at its roof and slowly an automatic shutter opens, leading sunlight in. As light falls on the nest, hundreds of bat-like Alien birds (apparently young, not fully grown ones) fly around screeching. Ali in panic runs into another dark room inside, as do the birds. Hearing his screams, the others come and break open the Coring room. When they open its inner room, the flock of flying creatures come out and quickly fly down into the coring shaft, apparently avoiding light in the room.
