Cylindrical Terrarium Wardian Case Bird Feeder

Construct the structural frame using mahogany strips joined with delicate mortise and tenon joints. Apply a high-quality marine-grade varnish to protect the wood from moisture exposure.

Incorporate clear acrylic or tempered glass panels into the framework to create a sealed environment. Install a hinged roof panel at the top to facilitate easy refilling of the internal hopper.

Design the internal seed hopper as a removable central tube that funnels feed into a base reservoir. This prevents the feed from touching the glass walls and ensures a continuous supply to the perimeter tray.

Attach decorative brass corner brackets to reinforce the structure and add an authentic antique aesthetic. Finish the project by installing a heavy-duty copper chain for hanging the feeder in a sheltered garden spot.
