Wolf (Canis lupus)

Recap of the last article and important note on the weights of wolves : 

1. Glaser's 175 lbs (79.37 kg) was full of meat. 22 lbs (10 kg) is the maximum recorded amount of meat in a stomach. Therefore, this wolf estimation would be 153 lbs (69.40 kg)

Which would still be the biggest wolf ever recorded in North America ! 69.40 kg

2. Gardner's 140 lbs (63.50 kg) alpha male in 1997. Pack of 16 wolves.

3. Jon Burch's wolves at a fresh kill [meat in stomach] : 148 lbs (67.1 kg] male and 110 lbs female [49.89 kg]

“Any wolf over 140 I would classify as huge,” Burch said.

Of the 179 wolves Burch has captured in and near the Yukon-Charley Rivers National Preserve since 1993 :

Average weight for adult males is 111 pounds [50.34 kg]

Average weight for females it is 97 lbs [44kg] .

4. Average for alaskan wolves according to the article sources : 100-110 lbs (45-50 kg) for males and 90 lbs (40.82 kg) for femalesé

5. Biologist Mark McNay studied wolves for 27 years in Alaska and weighed 300 wolves.

Biggest wolves he weighed [all had meat] : 143 lbs (64.87 kg) (male), 125 lbs (male), 118 lbs (Female)

Quote:“They were in exceptionally good territory that had lots of moose and caribou,” McNay said.

Quote:“If I caught one that was 143 pounds and it hadn’t eaten for a couple days it could be the same size as a 170-pound wolf coming off a fresh kill,” he said.

Other biologists agreed wolves are extreme opportunists when it comes to food.

Quote:

“You find that in stomachs pretty commonly — 20 pounds or more of meat, hairball and bone,” longtime Fairbanks biologist Rod Boertje said. “That’s how you get most of these 140-pound wolves.”

6. Boertje and Garder weighed 71 male wolves older than yearlings in the Fortymile herd’s range and the average weight was 106 pounds.

7. Of the 300 or so wolves that biologist Layne Adams with the U.S. Geological Survey has handled working in Denali National Park and Preserve and Gates of the Arctic National Preserve, the biggest was a 135-pound male in Denali.
