Abstract
A bird feeder construction of the type having a dish for receiving feed material and a hood member associated thereabove so as to protect said dish, not only from the elements, but also from access by undesirable bird species and other pests, such as squirrels and the like. Accordingly, the hood is not only adjustable in varying spaced positions above the dish but is further movable to a position wherein the terminal portions of the hood and dish are either on a level with each other or the hood extends therebelow so as to provide additional security to the feeding system. Additionally, even though the hood is so positioned with respect to the dish, it may at any time be freely upwardly withdrawn therefrom so as to provide complete access to the dish for refilling.
