The Chesapeake's latest reality stars are ospreys Tom & Audrey — until their chicks hatch and steal the show! If you haven't already, visit www.chesapeakeconservancy.org/Osprey-Cam, where the Chesapeake Conservancy's Osprey Cam has been offering a 24/7 look at the nest-building and egg-laying action at Tom & Audrey's nest site on a platform in the vicinity of Kent Island, MD. Also at the site is a link to a blog about ospreys, and Tom and Audrey in particular. All of the answers to this quiz are found at the site or the blog (or on page 31.)
