Secret Garden, Series 1 Episode 3, The Lake District

David Attenborough tells the story of an idyllic English country garden in the Lake District. Owners Chris and Liz love their outdoor space and do everything they can to encourage wildlife. In spring, the garden is full of life: the orchard bursts with blossom, the flower beds are abuzz with bees, and the pond is awash with courting newts. Love is in the air! But the breeding season is short, and the clock is ticking for the garden’s inhabitants to find partners and raise families. As night falls, a field mouse ventures out right under the noses of the garden’s predators. She tunes into the ultrasonic serenade of a male, inaudible to predators and humans. But before she heads out across the vast, featureless lawn, she employs an extraordinary survival strategy to make sure she will find her way home. She positions landmarks on the short grass. Field mice are the only animals apart from humans known to do this. A few days later, a new arrival swoops in – a weary traveller who’s spent six long weeks on the wing, crossing continents to reach this special place – a barn swallow. Of the 25 million gardens in the UK, he has returned to the one where he was raised. He prepares a nest in the hope that his life partner will soon return. In the pond at the bottom of the garden, a female palmate newt is looking for her own Mr Right. Flirtatious males waft perfumes towards her to catch her attention. She’s picky, but eventually one impresses her. Days later, she carefully wraps her eggs in the leaves of pond plants to protect them until they hatch. As summer arrives, mini dramas play out all over the garden, most of which stay unnoticed by the humans who live alongside the wildlife in this magical place.
