The wood duck's call, both sitting on the water and flying overhead, is a sound, which rings forth from all wetlands and swamps. The Wood DuckĀ from PrimosĀ® reproduces this sound and is a great confidence call when hunting other waterfowl. Blows when wet! Reproduces the high-pitched squeal of the wood duck flying overhead or sitting in the water. Requires very little air pressure to blow.
