RE: Tail Feathers and sexual selection

["Maurovic, Mauro (SAHC)" <>]

Hi all,
The comments by Stephen, Kit and Mark also remind me of the same eye
movements that a rainbow lorikeet, that I rescued, used to display when
he/she?? got very excited. He/she also used to arch the back upwards at the
same time as well as bobbing up and down, but the rapid size changes of the
pupil we remarkable.
cheers
Mauro

        " but I was made aware of the display function of eyes when
        watching my brother's Orange-winged Amazon.  It periodically dances
(last
        time I saw it, its favorite song was Paul Simon's "Will you be my
        bodyguard") and, along with bobbing and fanning its tail, it does
the most
        startling thing with its eyes: suddenly snapping the pupils from the
widest
        to the tightest "aperture", which displays the red and yellow iris.
Must
        be a modification of some normal display behavior..."
