Fascinating and fun: the OVA-Fairlynch joint talks

David Spears It was a privilege on Saturday 7 February to hear two distinguished experts who are noted for their stunning images of wildlife.

David Spears’ talk was entitled ‘Tiny Lives in Rivers and Estuaries.’  A Fellow of the Royal Microscopical Society, the Royal Photographic Society and the London Zoological Society, he studied Zoology at the University of East London and Neurobiology at the Open University before pursuing a career in wildlife photography.  He filmed with David Bellamy and David Attenborough before later setting up his own production company, Science Pictures.
 





 












A century and a half ago the Budleigh-born scientist and microscopist Henry John Carter FRS, pictured above, settled in retirement at what is now Umbrella Cottage on Fore Street Hill. Part of his retirement was spent identifying creepy crawlies that he found in local drains and bogs. 

Microphotography was not available, but the drawings that he made of the tiny creatures that he observed astonished the Victorian public.

Carter would have been staggered and delighted by the images that David creates, using modern high-powered electron microscopes, as seen in this photo of a tadpole. 

 
From award-winning photos of tiny amoeba to the smaller aquatic vertebrates, many of them found in the River Otter, his riveting talk took us through nature’s food chain with all its predators and victims.

We were shown bacteria which live on decaying leaves, pond skaters which feed on daphnia, water boatmen which suck the juices out of tadpoles — even a dragonfly swallowing a fish. We learnt about blue-green algae and the difference between malarial and non-malarial mosquitos.

David’s passion for his subject came across clearly. Like Carter he had been charmed by the beauty of his subjects: he enthused about the intricate jewel-like workmanship of “pretty diatoms” and the fascinating lives of vorticella — “very interesting little chaps” which behave like jellyfish.

For those members of the audience tempted to try and emulate David’s achievements he gave encouraging hints that microphotography was not beyond the reach of the average pond-dipper, occasionally mentioning equipment that he had “picked up on Ebay.”

The second speaker, Mike Langman, is equally passionate about birds. He worked for the Royal Society for the Protection of Birds (RSPB) at their headquarters in Bedfordshire, for nine years after he left art college in 1983. His bird illustrations can be seen in nearly every RSPB reserve. His work has been published in over 50 books and regularly appears in all of the UK’s birdwatching magazines. 

Mike’s talk was a more interactive presentation than the previous speaker’s, and had an amusing touch of the showman about it: mid-way through his opening introduction his mobile rang. For quite a few seconds I was taken in as I listened to a ‘conversation’ between Mike and his Auntie Flo about a bird that she had spotted. Later during the talk he asked the audience for a volunteer to stand out in front and draw a puffin, based on descriptive details that we did our best to provide.

“How well do you know your common birds?” was another test which we were faced with.  I felt I should have known better the difference between a blue tit and a coal tit. 
Still, nobody in the audience scored 100% when Mike asked us to draw the markings on a badger’s head.

There were plenty of wonderful photographs of birds. Trying to spot a Mediterranean gull in a flock of black-headed gulls and a goose in a gathering of swans were further tests where some did surprising well and others did dismally.

The lessons from all this fun and games were clear: it’s all about observation when you’re trying to identify our feathered friends. And drawing, rather than photography, is the answer.  The digital camera, clever though it may be, is no substitute for binoculars, sketching and notes. 

Both David and Mike showed us early pictures of their work from the time when, as youngsters, they were experimenting with microscopy and sketchpads. Which left me feeling rather sad I didn’t spot a single young person in an audience with an average age of 60. It was Saturday morning. I wondered how many teachers had recommended these two excellent talks to the aspiring naturalists, film-makers and artists that we hope our schools will produce.
