There
are all sorts of variations. In some groups of birds e.g. Button-quails, the sex
roles are reversed. Many species have mutual displays, like the water dances of
grebes. This message from Martin adds to my comment about the female sexual
solicitation behaviour by the Pied Currawong is far more obvious than the male's
courting behaviour. A female sexual solicitation behaviour is a common thing in
birds and I have no idea whether it may be more or less obvious relative to how
obvious the male's display is. The points to consider relative to the original
issues, include that display is not always about breeding display, there
are other reasons to display or sing and we may assume the wrong intention,
display is clearly not proof of breeding and singing alone can just be
territorial behaviour and /or trying maybe unsuccessfully, to attract a partner
(who may be nowhere near).
If cisticolas or anything else are only or mainly observed when
singing and we take that as a display for COG records, and that variously goes
into COG breeding records according to the varied wishes of the observers, then
even though they may well be breeding, without proper evidence of it, that would
make our records inconsistent.
Good
that another caught the "An original
Duckumentary" program.

always the male that is the actor... ".
While watching
the excellent "An original Duckumentary" I noticed that with the American Wood
Duck the female performs the display behaviour immediately prior to
copulation.
