发明名称 HAVEN FOR USE WITH A BIRD FEEDER
摘要 A haven for use with a bird feeder is provided that includes a collapsible spiral rod assembly having an upper end and a lower end. The spiral rod haven has a plurality of spiral convolutions and is selectively movable between a collapsed position and an extended position. The spiral rod haven defines an interior compartment when in its extended position. A bird feeder is positioned within the interior of the compartment. The bird feeder may be either a collapsible bird feeder, a tube-type bird feeder or any other type of bird feeder that may be positioned within the interior compartment of the haven. Small birds may gain access to the bird feeder by moving through adjacent convolutions while the convolutions prevent large birds or squirrels from entering the interior of the haven.
