Iolo Williams goes back ten years to 800 ravens roosting in Newborough Forest, Anglesey, and their extraordinary calls. He recalls a visit to Grassholme Island off the coast of Pembrokeshire in 1996 to see a colony of over 100,000 gannets. He also looks back at the wildlife of slate quarries, the breathtaking underground landscape of a mine in Blaenau Ffestiniog and a fantastic reef formed on a slate-boat wreck off the coast at Nefyn.

Other gems include the parachuting displays of skylarks and rock pipits, and a couple of boat trips with fishermen in Cardigan Bay and the Dee estuary. Show less
