Just posted this on another forum:

"Will" for expressing generic qualities is found in many texts.

"In a very good year when there is plenty of food, two chicks may survive. When food is scarce, the biggest chick will kill and eat the smaller ones."

(Then, now and always. General time.)

Here, it is not generic "will", it is future prediction:

"About 160 adult wolves will kill and eat approximately 1,800 big game animals a year, Bangs predicted. That is an increase of 50 percent. "
