Dolphin Diets and Nest Boxes

Connecting rural communities and cutting carbon emissions - a network of car clubs across rural Wales. Caroline Evans visits Llandrindod Wells to hear more.

We explore Gwydyr Forest in the Conwy Valley where long-gone lead mines mean the area is now home to around 90 per cent of the world's lead Moss.

The Dolphin Diet Detectives project - a new initiative of the Wildlife Trust of South and West Wales - receives funding to find out what species the bottlenose dolphins of Cardigan Bay are consuming. It involves the collection of dolphin faecal samples - not an easy task - but researchers hope the study will increase our understanding of dolphin and marine conservation in the future

And on International Dawn Chorus day, we hear about a new study of nest box-breeding birds by Aberystwyth University, to understand the impact of climate change on competition between birds.
