On my way home from work this evening, I saw a glimpse of what looked like a large bird of prey (maybe around 2 foot?) which had a very white belly and dark wings.
It was sitting in a tree, in fields not far from a river. I don't think it was a heron (though that sounds more likely?). Is there any chance it was an early osprey?
It was in the Bristol / Bath area if that helps. I will keep an eye out when I travel that way tomorrow...
I would say it is much more likely to be a Buzzard with very pale markings. They can have almost white breasts and although much rarer than standard colouration they are still surprisingly common.
