The seasonal bird show “Masters of Flight: Birds of Prey” returned this month to Stone Zoo in Stoneham. The show features a bald eagle, a red-legged seriema, a king vulture, a Eurasian eagle owl, and a black vulture. During the show, the birds fly in from overhead and demonstrate natural behaviors including several survival techniques and food foraging, as well as specialized physical adaptations. The show runs through Labor Day. For more information, visit the zoo’s special events page at zoonewengland.org/SZevents. Formerly known as the Middlesex Fells Zoo, Stone Zoo is located on a 26-acre site. The zoo was founded in 1905 and renamed in honor of former zoo director Walter D. Stone in 1969. Zoo New England maintains care and custody of both the Stone Zoo and the Franklin Park Zoo in Boston. For more information about Stone Zoo, call 781-438-5100.
