The intent of this research video is to provide audio clips and spectograms of a series of loud nocturnal vocalizations recorded on a small coastal BC island in the fall of 2016. These vocalizations have been attributed to the North American sasquatch. The calls were recorded during the hours of darkness, but occasionally in the evening, over a period of about two weeks in late September and early October. The island, Cormorant Island, supports the village of Alert Bay (population approximately 1000). In addition to the village, the island supports areas of old growth and second growth forest, a substantial wetland, and a marine shoreline. It lies at the western end of the Broughton Archipelago, a large group islands lying between Vancouver Island and the BC mainland. Two juvenile grizzly bears which appeared on the island in 2106, are considered to have swam via the nearest adjacent islands, the Pierce Islands, located approximately one and a half kilometres to the east. There is a history of sasquatch observations and sasquatch tracks by island residents. The recorded vocalizations are compared with similar vocalizations recorded in central Manitoba in 2106. Spectograms of both sets of vocalizations provide an acoustic signature as a graphic means of comparison and also as a means of determining the fundamental frequency (400 to 500 Hz) and the presence of overtones (up to 1500 Hz). It is hoped that the results of this preliminary research are sufficient to attract the interest of bioaccoustic specialists better qualified to categorize the sounds.
