Special Saturday Bird & Nature Walk -- Monarchs and Owls! Join Arboretum Naturalist Sylvia Marek for a free family friendly evening walk at Owen Conservation Park in the heart of Madison's west side.  Sylvia will take you to look for Monarchs and listen for Owls in this almost 100 acre natural area featuring beautiful hilltop with native oak opening woods and restored prairies on what was once UW Professor Edward "Buck" Owen's farm.  Along the way you will also see and learn about the plants and wildlife that call Owen Park home.
