We've had a pair of redpolls on the niger seed for the last two days. They are a similar size as siskins, in fact our first thought on seeing them was 'that siskins red'. I know they have been seen in Brecon and my brother sees them down near Wellington, but it's a first for us.
We had a pair of spotted flycatchers looking at the back of the summer house, so I quickly moved a nest box in. Perhaps a bit too hopeful but you never know.
