ABSTRACT:
An inverted ceramic container dispenses nutritional liquids through a short glass tube to hovering hummingbirds. The tube extends into the interior of the dispenser through a resilient stopper which engages a refill aperture in the dispenser. Various insulative properties of the ceramic dispenser protect the liquids from heat and light damage and loss. The rough unglazed inside surface of the dispenser neck establishes a tenacious seal with the resilient stopper. The unglazed exterior surface of the neck prevents dew and rain moisture from flowing down the outside surface of the dispenser to the tip of the glass tube. This surface moisture is objectionable because it wets the tip of the glass tube causing the nutritional liquid to drip out. The plastic nature of moist unfired clay readily permits the formation support loop integral with the ceramic body.
