It may well be that tail feathers are designed to be dropped (or at least
able to be pulled out readily easily) in an emergency. Certainly they seem
more 'sheddable' than flight feathers, for instance. However the bird would
then have to do without them until next moult. On the other hand it could
perform the trick once a year, unlike a gecko or skink which can only do it
once a lifetime.
