This is a window bird feeder, it has some very small holes in the bottom for drainage, I needed to ream them to clear them out. Being on the 4th floor of my building I also added a safety wire connected to my balcony.

This was the first iteration, I might make updates based on performance.

Uses 3M Outdoor window strips (very important that you use the UV rated strips, they have a little sun clip art on the blue side).
