Meet Mark H.X. Glenshaw: college library staffer by day, Owl Prowler by night, and self-styled Naturalist extraordinaire. For over 9 years, in all weathers, Mark has been observing a mated pair of Great Horned Owls (and their 26 owlets!) in this country's second largest urban park. He generously helps adults and kids to get out in nature too.

Charles and Sarah, as Mark calls these owls, invite you to meet their human student, fan and champion in this true tale of urban ecology.
