Abstract
I evaluated the effectiveness, suitability, and expense of 2 styles of predator guards for black-bellied whistling duck (Dendrocyqna autumnalis) nest-boxes. Guards evaluated were galvanized bottom attached shrouds and razor-ribbon wire. Both guards were effective against ground dwelling predators. The group not fitted with guards suffered a 55% overall depredation rate.
