The pied wagtail is a common bird. They are usually found on smooth ground and short grass, as they like to scuttle about chasing insects. The picture above was taken on the bowling green in Brockwell Park, which is perfect for them. I often see them in supermarket and service station car parks where they will usually be paired up. My RSPB book says they are very territorial at this time of year, even fighting their own reflection but they do usually roost communally. The females are slightly greyer on their back and have a smaller bib. As their name is well given as they constantly wag their tail up and down. They often engage short burst of frenetic flight hunting for insects. The pied wagtail is a subspecies of the white wagtail and usually only breed in Britain and Ireland, where as the white wagtail is more common in the rest of Europe.
