Abstract
A selective bird feeder is provided. The selective bird feeder includes a selective housing having a side wall and a base. A cover supported by the side wall of the selected housing and a seed holder is contained within the selective housing. The selective housing restricts access of relatively large birds and predators, while allowing access of smaller birds, such as song birds, to the interior space in which the seed holder is disposed.
