At the moment I am visited by one sometimes three a couple of times through the day. They head straight to the fat balls and peanuts. I remember early last year when the weather was really cold, we had long-tails in the garden all day feeding. I used to sit on a chair right next to them, the weather was absolutely freezing cold. They didn't mind me being there at all, they were more interested in feeding, so I expect they may increase in numbers to your garden if the temperature should drop
