The wolves in Yellowstone National Park are often the subject of debate as hunters say the predators are driving elk towards extinction and hurting livestock.

But National Park Service researchers say wolves have had a positive effect on Yellowstone's environment. They say they only kill elks and cows that are in failing health.

They also say more bald eagles and golden eagles are showing up to scavenge on wolf prey. The researchers are conducting a number of studies on the wolf population to better understand their behaviors.
