If you love birds, but hate getting up at the crack of dawn to see them, tonight's Evening Birding at Hallam Lake is for you. Presented by the Aspen Center for Environmental Studies (ACES), the two-hour outing takes place from 6 to 8 pm. Participants will learn about the area's native birds and have the opportunity to watch as they get ready to bed down for the night. BYOB - bring your own binoculars!
