If you truly want to get inside the mind of one of the world's most ruthless and silent killers, mark this Saturday, Nov. 22 on your calendar.

That's when Warwick County Park will host a nature program all about owls.

The program runs from 6 to 7:30 p.m. and will take place in the park office, 382 County Park Road, 3.5 miles west of the intersections of Route 100 and Route 23.

A slide show, mounts, pellets and two owls, a Great Horned Owl and a Screech Owl from the John James Audubon Center in Mill Grove will all be part of the program.

The program will conclude with a moonlit (and in all likelihood cold) walk along the forest edge with a guide calling in Pennsylvania Eastern Screech Owl in an attempt to see one hunding.

To register, which is required, call 610-469-1916 or to the www.chesco.org/ccparks and download a registration form. There is no charge.
