On the advice of the NABU, I decided not only in winter, but because of scarce food has become in the form of insects (a result of intensive insecticide use) to feed garden birds in the summer. this I lacked an inconspicuous suspension for fat balls. In Erdmann Meisenknödel without power with Aufhängekörbchen I found the ideal product. The fat balls seem to taste the birds well. I'm always amazed at how quickly I have to fill it up with the 4 dumplings "Knödelboy" again. I would recommend the product and will only continue to reorder without power when needed, the inexpensive dumplings
