A wall mount for Bird Buddy (https://mybirdbuddy.com/), which is fixed to the bird feeder with M4 screws and thus is more sturdy than others which use the pole mount instead.

Further, there are two options to mount it itself:

• screw it to a wall using the 4 holes (holes are 5mm in diameter)
• using zip ties, tie it to bars or poles by using 4 of the 8 holes depending on orientation and available mounting options (holes are 2x5mm and 5x5mm respectively)
