The present invention is a disposable wild bird feeder with the features that make it safe and easy to use but protected from being reused. A transparent reservoir containing bird seed is connected with a feeding base. The feeding base is threaded to an adaptor portion of the reservoir. A locking means between the internal threads of the adaptor portion and the external threads of the feeding base discourages the assembled wild bird feeder from being taken apart and refilled. The wild bird feeder converts from a first storage and shipping configuration to a second feeding configuration by partially unthreading the feeding base from the adaptor so bird seed is supplied to the bottom portion of the feeding base. A plurality of perches are supported by the feeding base. The perches are moved from a stored position to approximately a horizontal deployed position when the second feeding configuration is realized. A removable label is placed on the reservoir to provide a logo, directions for safe use and bird seed data.
