发明名称 Bird feeder
摘要 A bird feeder has a seed storage compartment at least partially defined by a side wall. Improved feeding ports are provided in the side wall through which birds may extract seeds from the storage compartment. Each feeding port comprises an opening in the side wall which is partially occluded by one or more resilient finger members. The finger members are arranged to prevent a free flowing escape of seeds from the storage compartment, and are flexible to accommodate forcible extraction of seeds from therebetween.
