I became absolutely fed up of feeding wood pigeons every day, the two it started off with, eventually became seven, so I decided to take action. I determined it was the wheat in the feed that was attracting them so I decided to mix my own feed. Proved more expensive however the upside being it solved the woody problem and we are now back down to two woodies with two beautiful collared doves to go with and a variety of other birds like blackbirds thrushes and starlings. At the same time my family of goldfinches had grown in number and the niger seed feeder was depleting at an incredible rate daily. The upshot of mixing my own feed by almost eliminating the wheat content and increasing the sunflower kernels is that the adult goldfinches are now eating sunflowers seeds and the sunflower seeds are attracting other finches. According to my copy of Birds of Britain I think I may have a female Siskin joining the goldfinches for their feed. Anyone care to confirm?
