Prevents nesting, but the !@#$%^&* birds still hang onto the wire grid
and poop into the chandelier :-(

Chandelier? more like suspended oyster lumiere.

Since there has been recent discussion on S.E.D of flexible plastics,
I was wondering if there's something available flexible enough to redo
my "bird cage" so that the birds can't cling to it?

It's Spring in AZ, 85°F today, so my need is immediate ;-)

how about a bunch of bristles (I've not seen birds on spiny cacti)
could be spring steel, stainless or linetrimmer line,

or just a cone of multiple nylon strands.

Thin polycarbonate sheet could work too it's reasonably heat tolerant.
anything under about .75mm should be flexible enough to take that form.
