50% of wolves diet is mature bulls in March
See the study results from YNP. No wonder hunting opps. decline. Do we have relearn this in OR? I guess the answer is yes, and we will be sorry, IMO. When they say old and weak, they mean mature bulls guys, especially when they lose their antlers for defense.
Yellowstone wolves again eating older elk
April 30, 2007
BILLINGS, Mont. (AP) — Wolves in Yellowstone National Park have returned to killing older bull elk for food after an early winter preference for young elk.
Doug Smith, the park’s lead wolf biologist, said the wolves’ out-of-the-ordinary emphasis on elk calves in November and December was followed by a more typical diet of large male elk last month.
“This is right in line with what they do in March,” Smith said.
Late last year, a survey by park biologists showed about 75 percent of the wolf kills were calves, 15 percent were bulls and about 10 percent were females. There was some speculation that the early mild conditions made it harder for wolves to get adult elk, so they turned to the weaker calves.
But in March, about half of the kills were bulls, roughly 25 percent were calves and 25 percent were adult females, Smith said.
The surveys are conducted every December and March to get an idea of what wolves are eating and how the population is faring.
