Bertha Dlugi’s Contribution to the World

Sunday, 30 May 2010

Bertha Dlugi’s invention, patented in 1959, was intended for parakeets and other birds that are allowed to fly freely about the house. “It is … a general object of the present invention to provide a garment to be worn by birds for receiving their excremental discharge to prevent it from being deposited on household furnishings when the bird is at liberty in the home and thereby avoid the consequent unsanitary condition.”
