Wildlife filmmaker Hannah Stitfall and wildlife film researcher Dom Davies enjoy a close encounter with one of our most mysterious birds, the woodcock, when they review another selection from the LIVING WORLD archive. The woodcock is a wader which spends most of its life in woodland where its wonderful mottled plumage makes it very hard to see, especially as they are nocturnal so most active at night. The population swells in winter when over a million more migrate here from Scandinavia and Russia in search of earthworms and insects which they probe from the ground with their long bills. Hannah and Dom also discuss another remarkable feature of these birds which is their strange roding flight call.

Living World : My Living World : Winter Flies
Where do flies go in winter and what happens to them? Wildlife filmmaker Hannah Stitfall and wildlife film researcher Billy Clark review another selection from the Living World archive to try and find out the answer. The original programme was recorded beside an icy pond in a woodland near Kidderminster where, with the help of pooters and ‘ghostbuster gear’, a surprising number of flies are discovered in winter including the stunning-looking dollies, best known for their metallic green sheen and long dancing legs!

Living World : My Living World : The Spined Loach
Keen naturalist Hannah Stitfall is joined by wildlife film researcher Dom Davies to review another programme from the LIVING WORLD archive. The subject today is Spined Loach - a fish you might never heard of because, whilst locally they are abundant, they are classified as a rare protected species and are only found in a handful of places in the UK. Also known as the Spotted Weather Loach because of their ability to detect changes in atmospheric or barometric pressure brought about by changes in the weather, they half bury themselves in fine organic sediment at the bottom of rivers or lakes during the day and then at night sieve the sediment, eating small shrimps and ejecting the mud and sand through their gills. As Hannah and Dom discover, these little fish also have some amazing survival techniques which enable them to survive low oxygen levels, whilst the spines which protrude from under their eyes are thought to help ward off predators.

Living World : My Living World : Jackdaw Roost
In this episode from 2011 Joanna Pinnock wonders what makes jackdaws roost together, and to find out more heads to the Cambridgeshire countryside with corvid scientist Dr Alex Thornton. Arriving in the dead of night they await one of nature’s spectacles, of thousands of jackdaws simultaneously leaving their night roost in a cacophony of sound. It is one of those winter spectacles often overlooked but rivalling any in the natural world. So what is actually going on here? For Hannah and Billy this gives them the opportunity to discuss corvid activity. Science is beginning to unravel the biology and social intelligence of corvids, recently dubbed feathered apes, but there is a lot still to learn about these familiar if mysterious jackdaws. If the morning was a spectacle, how will that compare with the evening gathering at the roost; some roosts have been recorded in the Domesday Book and are still being used centuries later?

Natural Histories : Aye-Aye
Think sprite or hobgoblin and you are nearly there when it comes to the Aye-Aye, surely one of the weirdest looking creatures on earth? With its large saucer-like eyes, massive ears, and long skeletal middle finger which its uses to tap for grubs on logs, this lemur both fascinates and terrifies us. Endemic to the forests of Madagascar, some local people believe that if one looks at you, someone in your village will die. They even hang up an aye-aye on the edge of the village in some areas to ward off evil spirits. We are responsible for the demise of the aye-aye in other ways; by destroying the forests on which it depends. But as we hear, get up close to an aye-aye and you’ll meet one of the most alluring and watchable mammals on the planet. Not merely a creature in close harmony with its disappearing world, but as Brett Westwood and Verity Sharp discover an ambassador for conservation which still has us in its thrall.
The BBC Natural History Unit produces a wide range of programmes that aim to immerse a listener in the wonder, surprise and importance that nature has to offer.
