Adventures with Britain''s wild mammals. Britain is teeming with wildlife, often in the most unexpected places. There are quarries where rare bats hang out with pot-smoking teens. In Glasgows urban parks water voles are thriving without water. Our coastlines are bustling with grey and harbour seals. Thats the good news. The bad news is that a quarter of British mammals are at imminent risk of extinction. Tim Kendall and Fiona Mathews take us on a safari unlike any other. Armed with binoculars, a Thermos and, regrettably, an inexhaustible supply of puns, they travel from Scotland to the Isles of Scilly in search of their elusive subjects.
