Have you ever heard a strange bird singing in the background of a movie and wondered what it was? You may have been hearing the song of the whip-poor-will. Join Nancy Landry, refuge volunteer and avid birder, for an evening of listening for the song of the whip-poor-will and other nighttime birds. Participants should meet Nancy in the Hellcat Parking Lot (on the refuge) 15 minutes before the program start time (see date-specific start times, above). Dress appropriately for weather conditions. Preregistration is required – Please call (978) 465-5753; enrollment limited to 15 people.
