The extra plank I put on the Birdy Bistro seems to be doing the job of attracting birds which prefer not to sit on feeder perches. Today I got a very brief glimpse of a bird I haven't seen in the garden before now. Hopefully it was a female Blackcap.
My thanks to Keith (Caldecotte Lake) for a confirmation of its ID. In fact it was seeing the small birds feeding on the bridge rails in his videos which gave me the idea of putting up a flat surface for the birds to feed on.
Poor, rushed photos taken just before it disappeared:
It returned later giving a few more opportunities for a better shot:
