The pot tips over if bigger birds like pigeons try to eat from the peanut butter, enabling smaller birds to enjoy their food. As you can see in the picture, the birds in my garden absolutely cleaned the peanut butter out.
Used a 4mm wood stick to make the landing spot. The stick is reused, it came from some garden plants I bought.
I used this peanut butter (please only use peanut butter suitable for birds)
