A squirrel proof bird feeder having a cylindrical reservoir for the containment of seeds and having at least one opening in the wall of the reservoir and one seed port for each opening, said seed port comprising: a platform having an opening congruent with the opening in the wall of the reservoir and a tunnel having a first opening defined by the opening in the platform and extending from the first opening through the opening in the reservoir, into the interior of the reservoir and terminating in a partially occluded second opening, effectively discriminates in favor of small birds, and especially against squirrels, by limiting access to seed within the reservoir.
