New guest at my feeder, a great spotted woodpecker
It actually manages to get some food from it with the long beak. I also suspect it to be the bird who picks up the peanut that I lay out in one of the flower pots every day.
I have one that live in my backyard (Ohio/USA) or at least someone who looks very similar. It eats the black oil sunflower seeds i put out, but seems to prefer ants or other insects
I built this myself from sticks, wire, a plastic lid from a box of licorice, a lid with seeds and a small plastic bucket with some fatty homemade tit food. I stuck it into the flower pot, but it is quite shaky due to pigeons landing on top of it. And parakeets and apparently woodpeckers :)
