ABSTRACT:
A system covering an area of ground for adverse conditioning web-footed aquatic birds against roosting in the area comprises an array of elongated members each sufficiently thin that a web-footed aquatic bird cannot roost upon an individual member and each sufficiently spaced in substantially horizontal planes from adjacent elongated members that a web-footed aquatic bird cannot roost simultaneously upon a plurality of the members, the array being sufficiently closely spaced to the ground at the aforementioned area to prevent the birds from alighting directly into the area.
