Iolo Williams seeks the wild side of towns and finds birds and animals that have adapted to life on the street. They have discovered that it is a great place for food and also a safe place to raise a family. Some
commute daily to town - birds simply fly above the traffic, while four-legged animals use their own 'rat runs'. For these wildlife townies, the street is a place called home.

In this urban wildlife tour, it's summer in town. Gulls are rearing chicks and are causing havoc on the streets of Aberystwyth. On the outskirts of Aber, badgers are dodging cars on a busy main road as they set off on a nightly expedition for food in the town's housing estates.

In Conwy, jackdaws have set up home on the castle walls. Pembroke Castle too has its jackdaws, and a beautiful mill pond which attracts otter families looking for eels. And on a warm summer's night, hundreds of bats come to feed on insects.

Also in the programme, the fastest birds in the world - peregrine falcons - are hunting prey in Swansea city centre, and an alien species of toad is keeping people awake at night in Llandrindod Wells. Show less
