Abstract: A shield device is provided for preventing entrance of birds into a gutter underlying a roof comprised of corrugated panels. The shield device is comprised of a substantially flat shield member and a bracket centrally disposed on the rear face of said shield member. The bracket is comprised of a shelf portion and gripping means positioned beneath said shelf portion adjacent the outermost extremity thereof. The gripping means are adapted to enclasp and thereby frictionally engage a lip associated with the front edge of said gutter. A multitude of said shield devices is utilized to occlude the archways formed between adjacent corrugations resting in abutment with the front edge of said gutter.
