I'm going to arrange with this egg who leads the orchestra that your female shall sing my chappie's song downstairs one night during dinner.

"How can a female that can't sing communicate to a male about a song?"

In at least 200 bird species, males and females sing tightly scripted duets throughout their relationship.

Both males and females sing this song, often perched from a vantage point such as a stump or fence.

Although most of the singing is done by the males, females that are ready to mate may also sing in response.

Since the females do not sing songs, they are in charge of providing the feedback.

Males and females sing in the mornings during the breeding season.

Incubation lasts 13 to 14 days and during this time the female does not sing at all.

"They say that females can't sing in Iran, but we have lots of great male singers with very great lyrics," he said.

The songsters are more commonly male although females also sing on occasion.
