LANCASTER â Who calls in the night? Who glides on shadowy wings in silent flight? What makes owls such extraordinary night hunters? A Squam Lakes Natural Science Center naturalist will present a program Thursday via Zoom on three of the state's owls to help people find out what is myth or fact about these nocturnal birds. During the program, the naturalist will instruct participants on using the interactivity features available in Zoom. Depending on the age and number of participants, this may include using the virtual hand raise, voting yes/no, filling out a poll, giving a thumbs-up and using the chat window.
