A day of guided nature walks for up to 3 guests at your choice of sites in eastern Massachusetts. Give Mark Rosenstein a wish list—bald eagles, great horned owls, or anything else—and he will try to show them to you. Locations include Plum Island National Wildlife Refuge, in Newburyport; Great Meadows National Wildlife Refuge, in Concord; Rock Meadow, here in Belmont; and many others. You will receive copies of photos documenting the day’s finds. 

Mark will treat the group to lunch. Date and time to be negotiated. Some targets are best observed at certain times of year, and often the best viewing is shortly after sunrise.
