Before idly tossing it into conversation I want to be sure I've got it
right.  "Schizochroism" has a sort of split corvid flavour in its probable
pronunciation  that seems a bit suspect.  Could there be a typo?  Should it
be "schizochromism"? ... Danny?

There's a pied Blackbird on Lord Howe Island that frequents the area around
Thompson's store and the Blue Lagoon apartments next door.  I photographed
it in '96 and it was still there Dec 28, '97.  What can I say it's
suffering from?

Cheers.
