Female wolf 1686F was wearing a radio-collar that was near the end of its battery life. We needed to change her collar to prevent losing radio contact with her. The conventional method for catching a wolf to change its collar is to set modified leg-hold traps. For a mother with young pups, however, that’s not an option because there is always some risk involved (albeit small given the design of the trap). Instead, we decided our best option would be to sneak up to her den without being detected and capture her in a net as she exited. As you can see from the photo every once in a while a plan comes together!
Once her collar was replaced, we processed her pups, placed the pups back in the den, followed by mom, and moved on to our next den search.
