Abstract: Various birdfeeder designs are provided for flowable bird feed such as seeds or nectar. In one design, the birdfeeder (100) has a housing including first and second receptacles (102 and 104). The receptacles (102 and 104) are intertwined to form a double helical configuration. A large number of feed ports (106) can be distributed across the receptacles (102 and 104) to attract a large number of birds in a small area. Partitions (116) within the receptacles (102 and 104) define a number of feed chambers (118) to supply feed at the feed ports (106).
