Bird calling from low bush in open savannah. Recording amplified and high pass filter applied using Audacity.

• Extract from a recording session. This extract has been filtered (High pass 1000 Hz)

• Habitat: Open area / dry bush.

• Male and female usually stay close each other on the top of a tree when they start to sing in duet. A duet sequence is composed by many repetition of a same duet type. Each population recorded (two) seems to use two duet types to communicate. The functions of these duets are not really clear (mate guarding / territory defense). There are a gender dialect and a population dialect.

• There is a visual sexual dimorphism between males and females. Females have a black plaston, lacking for males
