Colorado Parks and Wildlife (CPW) fitted two male wolves in North Park, CO, with GPS collars on Feb. 2.
One of the wolves, 2101, was recaptured two years after his initial capture, and the other wolf, 2301, is presumed to be one of 2101’s pups, born in 2021.
“2101’s collar had failed and we could see it was damaged. Wolves are rough on collars and that’s to be expected that in time collars will fail,” said CPW Species Conservation Program Manager Eric Odell in a statement.
“Refitting 2101 and having a second GPS collar will allow our biologists and wildlife managers to continue learning about the behavior of these wolves,” said CPW Acting Director Heather Disney Dugan.
A CPW-contracted company darted the wolves from a helicopter, allowing the collars to be fitted by field staff on the ground. CPW encourages the public to use its wolf sighting form if they see a suspected wolf, found at cpw.state.co.us.
