Using the traditional bottle cup

This is the way I use the traditional bottle cup that comes as a set of cups meant for the Oriental white-eye. Fill it to the brim with wax then carve out a little concave cavity. Enough for a single drop of nectar. That way, feeding of nectar can be given sparingly, also the hassle of cleaning the impossible to clean bottle is avoided.

Whether nectar or some other liquid food, I feed undiluted. Diluting with water tends to make the stool watery.

Caution: liquid wax is combustible if touched naked flame, so be careful.
