A modular system and method is provided that enables the consumer to design/build his or her own bird feeder based on interchangeable modular components that include multiple bases of different styles, multiple nutrient reservoirs of different styles, and one or more additional components, each having different styles. The system and method provides an on-line store that allows consumers to view the various styles for each component and to select their own base, reservoir, etc. Once the desired components have been selected on-line, a bill of materials listing the components is printed at a manufacturing facility where the selected components are pulled from a common inventory, assembled into a custom feeder and shipped to the consumer.
