We have a good collection of birds, but they have to "find" your feeder, if it's new, and will gradually come. They quite like it near a tree or bush so they feel safer, with somewhere to hide.
Ours love half coconuts stuffed with fat/seeds and sunflower hearts which we buy in a big sack. I love the gang of long tailed tits - pretty little birds. I buy good quality, previously tried cheap £1 shop and sometimes I think the fat balls were a bit rancid and not at all popular.
What gives you a warm feeling? 🥰
