The great tits are the most common visitors, there are about a dozen of them. They are well-behaved, select their preferred seed and fly to a tree to eat it.
The willow and blue tits are also regular visitors, but they are in the minority: there is only one willow tit and 2 blue tits. They are also very shy and don't like getting their picture taken.
Sparrows are some of the less behaved visitors. They are not as agile as the tits and prefer therefore to sit at the buffet and stay there. In the middle of the polar night, the sparrows often sit here for hours during the night. The green finch is a more recent visitor.
And last but not least, the magpies, of course. They come to clean the floor.
