(CNN)We don't know what this fisherman was trying to catch, but it probably wasn't a great horned owl.
Abandoned fishing line snared a great horned owl in Colorado, but humans worked together to free it
Colorado Parks and Wildlife enlisted firefighters' help to reach a great horned owl that became trapped in fishing line in a tree on Thursday at Harriman Lake Park in Jefferson County.
The owl dangled motionless in midair until rescuers were able to reach it and clip the lines.
The owl had some soft tissue damage and was taken to the Birds of Prey Foundation for rehabilitation.
She was treated with anti-inflammatories and will rest for a couple weeks before being taken to a flight cage for evaluation, Colorado Parks and Wildlife said on Twitter.
The agency warned anglers to pick up excess fishing line so as not to endanger wild animals.
Great horned owls are found throughout North American habitats, according to the National Audubon Society, and are "aggressive" hunters.
