Fairy wrens

Hi G.Crompton,

I presume that you are referring to males in non-breeding as they lose their 
distinctive colouration.  The tail of the Variegated is longer - not a great 
character unless you have both together.  The blue in the tail of the 
Variegated is paler, that of the Superb is a dark blue.  The illustrations 
in HANZAB show a black area in front of the eye of the Variegated (which I 
seem to remember from the field) but this is absent in the Superb.  Of 
course, the best way is on call, although similar, the calls are quite 
distinctive with experience.

Regards

Greg Clancy
