Chris Packham and Kate Humble are in Norfolk with live updates from the Springwatch animal stars - kestrels, plovers, skylarks, swallows, finches, barn owls and more - as their real-life family dramas unfold. Chris also meets one of his wildlife heroes, a man who's given his life to studying a jet fighter of an aerial predator - the sparrowhawk. Simon King gets to grips with Dorset's rich reptilian population, from venomous adders to green lizards.
