Un mésange (blue tit) clings to the feeder while pecking at the seed and suet.
I got this feeder many years ago. It's specially designed to hold several boules. As I mentioned yesterday, I hang this from the railing of our front deck during the cold months. It sometimes takes the birds a day or two to realize it's there, but once they do there's no stopping them. It didn't take long to learn which birds liked to feed here and what they're called both in French and in English.
