摘要

A new bird feeder and drinking fountain for birds, characterized by the fact of being constructed by a single piece of wood emptied by any suitable means, adopting both its interior and exterior walls any convenient shape, equal with respect to each other or different from each other. Yes, no interstices where the parasites of the caged birds can lodge and reproduce. (Machine-translation by Google Translate, not legally binding)
