Calls of male anurans during breeding seasons are species-specific identification tools. However, males cease calling after any nearby disturbance, including those of researchers. I proposed a variation on current methods that attempts to reduce this lag in calling after researcher-created disturbance by utilizing the propensity for competition in male frogs. I surveyed 14 breeding sites in Cabell and Wayne counties during the 2010 and 2011 breeding seasons. First, I used traditional visual encounter surveys (VESs). After using automated recording devices to gather site-specific recordings of calls of all species present, I conducted secondary VESs while playing these playlists over a ...
