The unique proven design simulates the presence of a predatory bird such as a hawk or falcon keeping the crop eaters and pesty birds or animals scared off. The flying profile of the Black Hawk, Black Eagle and Great Eagle is achieved by the three pin hanger which keeps the silhouette in a balanced and stable position, even in a strong wind. The Black Hawk, Black Eagle and Great Eagle are made from environmentally safe and durable plastic. The plastic is corrugated to provide additional strength.

Invented and tested in Europe in 1995, the Black Hawk has proven to be the choice for berry crop protection with over 50,000 units sold.  The Black Hawk and Black Eagle are effective on all unwanted birds, even large species such as the Canadian geese as shown right.
