Lovely thread. In my old house I was so lucky, had every bird you could think of, lots & lots of them every day. I got a bird's eye view through my bedroom window as they loved my conifer tree.
In my new house I'm trying to coax some robins and other little birds, not successful yet. Have 3 squirrels that I throw Monkey nuts down on the patio for, they are so funny, so agile.
I've found, as others have said, that the fat balls go untouched and the nuts I put in the feeders go mouldy. Tesco's bird feed seems the favourite. I get 2 lovely doves every day on the feeder, only occasionally the little birds and robins that I love. I'm trying to get it right with the food stuff for them and reading the advice on here.
On returning home recently, my son showed me a picture of a Sparrowhawk that had visited our garden whilst I was out, wonderful! Till I zoomed in and saw it was eating a Bluetit
