Champlain Area Trails will once again sponsor one of the most popular hikes, the Owl Prowl, on Friday, December 15, 5:30 pm at the Black Kettle Farm Nature Trail in Essex. This hike will be led by naturalist, Gregg VanDeusen, and will answer numerous questions about owls, the fascinating hunters of the night. Participants will also learn about the various species of owls in the Champlain Valley and will make owl calls to elicit their responses. All ages are welcome on this family friendly hike, but space is limited and advance registration is required. Call the CATS office, 518-962-2287 or register on the website, www.champlainareatrails.com/our-events. Cost is $10 per person, $15 for a couple, and under 21 are free. Dress appropriately for the season as the class may remain in one spot for some time.
