Menagerie, a recent series on the New York Times, “explores the strange and diverse ways the human and animal worlds intersect.” This first installment looks mainly at the various moral and philosophical conundrums that arrive via live-streaming nature cameras. In this case of an eagle camera in Decorah IA, when should park rangers intervene to save a dying eagle-chick. The series which is conducted on the opinionator pages, is written by Jon Mooallem.
