Acquire a pre-cut clear acrylic window feeder housing or construct one using high-impact clear polycarbonate sheets joined with specialized acrylic solvent cement. Ensure the removable interior feed tray features fine laser-cut drainage slots across its entire base to promote rapid water runoff after rain showers. Thoroughly clean the targeted exterior window glass surface using a mixture of isopropyl alcohol and water to remove all dirt, oil films, and grime residue. Moisten the rubber seals of three or four heavy-duty industrial suction cups mounted on the back panel of the acrylic feeder housing. Press the suction cups firmly against the prepared window glass, squeezing out all trapped air bubbles before sliding the seed-filled tray insert into the secured housing channel.

Idea 9: Covered Log-Cabin Style Wooden Tray Feeder
How to Make
A log-cabin style tray feeder combines open platform feeding with charm, featuring stacked miniature wooden dowels or small branches that form rustic side walls. This decorative approach elevates simple square tray designs into architectural garden features that resemble cozy woodland cabins. The raised log walls help contain larger seed mixes and whole peanuts during windy weather, preventing seed from blowing onto lawns below. Pairing the log wall structure with an oversized, removable wooden roof hatch provides superior weather protection while simplifying routine cleaning access.
