What Is a Canvas Back?

Archaeologists discovered 11 canvas back decoys in the love lot cave as well as a few others imitating Canada geese, snow geese, whistling swan and mergansers. The ancient humans that built them used to lead rushes to create the decoy shape and then tied real duck feathers to the woven cords. Archaeologists believe these decoys were placed on water with a fine net above them which entangled birds that tried to land in the spread.
