Ok. Here is a better image. It does indeed look like a masked Wagtail. If people are going to descend on the village I would ask they remember that this bird spends its time on my roof and the roofs of my neighbours. It will be very intrusive for them to have bins trained on the houses all day. The village has no carpark, narrow roads and no facilities. Please be respectful.
Err...if this is a masked wagtail......what`s it doing here, on my roof??
