a pair of hunters commit themselves to stalking game. A crow's nest is not a normal type of purchasable blind, but an improvised position, built by using locally discovered natural flora (tree branches, moss, snow (during winter) or sand (during summer), etc.). A crow's nest works in most environments and provides a good lookout point (hence the name) when built in an elevated position like a hillside or top of a hill. The term is sometimes used metaphorically for the topmost structures in buildings, towers, etc. Such structures are often referred to as a Widow's walk. References External links Shipbuilding
