With spring in full swing (or is it summer?), our nests are full to bursting. It's a season of new life. As well as all our live nest cameras, tonight's Springwatch showcases some of the season's most recognisable stars.

The call of the cuckoo is a sure sign spring has arrived, and Michaela wants to hear it first-hand! Megan McCubbin revels in Kielder Forest being one of the best dark sky locations in the UK and what that means for its wildlife. Over on the Isle of Mull, Iolo Williams is investigating the comings and goings of one of his all-time favourite birds, the hen harrier.

Chris Packham and Michaela Strachan take a live look at our nest cameras from Norfolk - but it's the badgers that steal the show with some mind-blowing behaviours captured on camera.

Iolo Williams goes out in search of some white-tailed eagles out feeding on the Isle of Mull, while Megan McCubbin continues her road trip across the north east of England as she arrives at Hauxley Nature Reserve to showcase its coastal wildlife.
