A Cable-Chain Device for Locating Duck Nests

Abstract

Abgract: A cable-chain device towed between two vehicles was developed for locating occupied duck nests in brushy, herbaceous, and grassy cover types. Twenty-three of 29 previously located gadwall (Anas strepera) and blue-winged teal (A. discors) hens were flushed from their nests with the drag for an efficiency of 79 percent. Eighty acres of nesting cover can be searched in 44; hours by the method described.
