Calceolaria uniflora is an ornithophilic plant and is pollinated by the Least Seedsnipe. The Seedsnipe eats the conspicuous white floral appendage on the lower lip of the flower, which is high in sugars. While the Seedsnipe pecks at this appendage, the stigma and anthers of the flower tap the head and back of the seedsnipe distributing and receiving pollen, ensuring that pollen will be transferred to the next Calceolaria unifora that is visited by the Seedsnipe.
