New to this just seen a white crowned sparrow on my feeder in the woods behind my home in Somerset
My friend has just sent me a picture of a Reed Bunting which looks more like what a saw. I'll definitely try and get some pictures, highly likely to be a UK bird rather than one that's flown 5000 miles to feed in my garden!
The female in this article could cause confusion ...

Sounds much more plausible. but it will be interesting to see whether you can capture a picture.
