As pronounced as they are in the picture, I imagine! So female chaffinch.
Doesn't look that pronounced to me, hence the question
Dave, I was just suggesting that the picture is of the actual bird that Pat saw, rather than a stock one. I don't really think of a female sparrow as having wing bars, certainly not at rest (which I frequently am).
Peter you are correct its a photo I took of one of the visitors to our feeders.
We do get sparrows of both kinds and its definitely not one of those I can spot them by now
Counted a mixed flock of 18 house and tree sparrows under the feeders last week.
