ABSTRACT:
A two-piece duck caller device simulates the call of the mallard drake using a sounding body and a resonance chamber encompassing the sounding body. The sounding body includes an elongated blowing stem, a whistle portion with an air vent and a flared exhaust portion. The resonance chamber is a hollow tube of sufficient diameter to encompass the sounding body with the end of the blowing stem protruding from one end of the resonance chamber and the flared exhaust end protruding from the other end of the resonance chamber. The resonance chamber has an air vent aligned with the air vent of the sounding body in the assembled duck caller.
