We take a look at the beauty of a green, iridescent, overlooked invertebrate as well as a fascinating insight into the family dynamics of the long-tailed tits in spring. Chris Packham and Michaela Strachan take us behind the scenes in Norfolk, showing us the inner workings of our live nest cameras. Iolo Williams is searching out seals on the Isle of Mull, and Megan McCubbin continues her seabird spectacle, looking at the spring visitors to Coquet Island on the Northumberland coast.
