A dryer vent designed to prevent bird and rodent ingress through the vent and further to prevent lint build-up includes a flap which has an edge portion recessed within the main body of the vent preventing birds and rodents from grasping the flap and opening it. Further, the dryer vent includes a rotating member such as a paddlewheel or a fan blade which rotates in response to air flowing through the vent thereby frightening birds and rodents.
