Iolo Williams continues his quest for wildlife in Welsh towns. This time, he finds foxes, badgers and otters roaming during the night. In Wrexham, badgers are visiting a housing estate and they take an occasional vegetable from the gardens. In Haverfordwest, foxes are using a path through a church yard to access the town and they look for food near rubbish bins in Carmarthen.

This time, Iolo discovers rats in Llanelli and catches mice in Bala. In Merthyr Tydfil, a grey wagtail has built a nest in a cage above the Taff. In Carmarthen and Llandudno, gulls are taking advantage of life on the street. And in Gorseinon and Dolgellau, beautiful and rare birds visit gardens.
