Willy Wagtail is a unique kind of fantail flycatcher. It is like a mixture of white Wagtail and fantail flycatcher. It is different from other fantail flycatchers. Willy Wagtail is a black-and-white fan tailed flycatcher, which is larger than other fan tailed flycatchers.
Willy Wagtail likes to move on the open ground rather than in the forest like other fan tailed flycatchers. When it stops, its tail swings like a Wagtail, but the way of swinging is different from that of a Wagtail. Willy Wagtail, a black-and-white flycatcher, is found all over Australia and is very common in cities and wilderness.
