Abstract: A dryer exhaust hood that prevents birds and other creatures from entering a dryer ventilating system. The guard includes an air-pervious panel sized to fit over the exhaust opening of the exhaust hood, a pair of spaced guard flanges that overlie the flanges on opposing sides of the exhaust hood, and a pair of resilient clips that frictionally engage and releasably secure the guard flanges to the hood flanges. The guard also includes alignment tabs that extend from the air-pervious panel to engage portions of the exhaust hood adjacent the exhaust opening.
