Japanese quail
Some 28 different call types have been distinguished based on the circumstances in which they are used and the various behaviors that are exhibited during the call. The call types of the Japanese quail differ between male and female, the same stimulus resulting in differing vocalizations. Most of the calls used by this quail are present after five weeks of development; however, they remain relatively changeable until sexual maturity is reached. The typical crow of the Japanese quail is characterized by two short parts that precede a final, major trill.
