Our last house (tied accomodation) was in the middle of a wood. The list of birds was endless. Nuthatches are angry little bastards!
I used to make my own fat balls out of lard, seed, nuts and bread. It used to cost a fortune, but it was great.
One thing I did was get a fence post, drill holes up and down it and poke peanuts into the holes. It was laborious but the great spotted woodpeckers were straight in on it, only 6 feet from the window.
Outside the back we had crab apples. The GSW's used to peck into them for the seeds. I was sat on the back step one day and there was an adult and juvenile woodpecker feeding on the apples when a Sparrowhawk steamed in and had the juvenile. It knocked the crap out of it, no more than 8 feet from me. After a few seconds it was off with it. The adult woodpecker spent the rest of the day in the tree frantically calling.
If you have Bullfinches in your area try planting some forget me nots, they love the seed.
