“This tiny bundle of energy in my hand…”: John Altringham talks to the Hoopoe about bats

John Altringham, author of Bats: From Evolution to Conservation, discusses the appeal of bats, what they are, and how we should think about their conservation needs.

 

Bats: From Evolution to Conservation jacket imageHow did you first become interested in studying bats?

I was taken to a Natterer’s bat roost, almost 30 years ago now, and saw my first bat close up. I was a research scientist in biomechanics – trying to understand evolution’s engineering problems and solutions. This tiny bundle of energy in my hand was an engineering marvel I’d never really thought about, so I went away and read about bats. However, I didn’t read just about flight and echolocation, the subjects that came immediately to mind. As a zoologist and conservationist, I read more and more widely and became increasingly fascinated. Bats became an important ‘extra-curricular’ activity, but it was many years before they displaced biomechanics in my work. However, the seeds were most definitely sown during that very first encounter.

We all know what bats are, but – what exactly is a bat?

A bat is the only flying mammal and one of nature’s few echolocators. With these ‘skills’ it has evolved and radiated into the most diverse, the most widespread and the second most speciose group of mammals on the planet. A bat is a small mammal with the lifestyle of its much bigger cousins. It lives a long time, but only produces one baby a year. It lives within often complex social units, exhibiting complex behaviours, and makes use of the landscape on a grandiose scale through the seasons. It shows a bewildering range of ways that an animal can makes its way in the world. It is an important cog in many ecosystems, as predator, pollinator, seed disperser. Its contributions to the human economies of the world are only now being determined and appreciated. Likewise its value as an indicator of the planet’s health. It is a source of endless fascination, study and appreciation.

Why do you think there is such popular interest at this time in bat detection and conservation, and what can we learn from studying their ecology?

I really think that bats sell themselves. The formation of the bat conservation movement, some knowledgeable and enthusiastic activists and some cracking documentary footage are the catalysts in the bat conservation movement – the bats themselves do the rest, if we just show the world something of them.

Bats are also surprisingly accessible. It is relatively easy, even in suburban areas, to see and hearBats: From Evolution to Conservation internal image bats, sometimes at fairly close quarters – you can’t say that about many wild mammals. They often live in close proximity to humans, you don’t have to be particularly stealthy, and they just get on with life while you watch – they have a lot to offer the casual naturalist. However, there are plenty of challenges for the more dedicated naturalist.

The need for conservation is pretty self-evident. Bats need large home ranges in connected landscapes, they rely on threatened habitats for both roosting and feeding and they are slow to recover from population setbacks. However, there are modest things we can do to help them, from practical conservation to education, which encourages widespread involvement – and success fuels further effort. Conservation needs passion and commitment – bats appear to have the charisma to generate them.

Conservation gets a big chapter in the book – it is the focus of a large and growing proportion of ecological research. There has been a lot of bridge building between research ecologists and conservation practitioners in recent years, but we still have some way to go. I’ve tried to highlight some of the issues in this chapter – evidence-based conservation is the future!

What can we learn from bats? Where do I start?! Science is all about understanding how the natural world works. Everything we learn, from the ecology of individual species to the general processes that govern the way ecosystems function, comes from the study of appropriate ‘models’. The sheer diversity of bats means that they offer useful models to study all sorts of things – just look at the topics I cover in the book.

How do you see the future for bats?

Bats: From Evolution to Conservation internal imageI have no idea what the future holds, for bats or the rest of biodiversity. I do think bats are among the more vulnerable animals, so looking after bats is a good way to protect other animals and plants that share their habitats. We have a growing knowledge about what we are doing wrong to our environment and what we need to do to begin to put things right. However, there is a lack of will among politicians and the ‘captains’ of commerce and industry to provide the conditions and the resources to do it. Lots of talking the talk, little walking the walk. Conservation will always be a compromise – but the balance point is far from the right place. Too many people still think of conservation in terms of what we sacrifice to achieve it, not what we gain from it. We need more objective science in conservation, alongside the passion and hard work. They provide the evidence that forces people to act and they help us to decide how to use most effectively the limited resources we have at our disposal.

Life with Birds – an interview with author Malcolm Smith

New from Whittles Publishing, Malcolm Smith’s Life with Birds: A Story of Mutual Exploitation zips around the world picking up sublime and ridiculous, sobering and frivolous facts from all its corners. Truly bulging with bird-lore, this makes for an engrossing read for all ornithology enthusiasts.

Life with Birds jacket imageWhat’s your background in the bird world, and how did you first become interested in avian-human mutual relations?

I think I’ve always noticed bird/human interactions wherever I’ve been – though probably more subconsciously – until I began to think about compiling and organizing them into chapters for the book.

It’s been part of a life-long interest in birds combined with a training as a biologist, though with very limited time to pursue these interests personally when I was Chief Scientist at the Countryside Council for Wales.

 

From a 10ft high Jackdaw nest at Eton college and the silvery bird trills of Vivaldi’s Flute Concerto in D ‘The Goldfinch’, to the 1,728 word vocabulary of Puck, the world’s most literate budgerigar, it seems there is no bird fact left out. Have you always been an intrepid collector? 

Quite the contrary, there are probably just as many examples of bird/human interactions left out of my book!  I’ve tried to include examples of all the major ones and many of the more unusual, bizarre and intriguing. But I had to be selective! It would be quite possible to write a whole book on birds inspiring literature and art for example but I particularly wanted to weave an interesting story using a whole range of examples to show how widespread our links are with birds.

While parts of the book have a more light-hearted, even irreverent approach, you do take a serious look at exploitation. How do you see our relationship with birds as we move through these challenging and changing times? 

I think most people will continue to be oblivious to birds, almost forgetting that they eat them regularly, make use of their feathers, see them every day on their homes and in their streets, and hear them almost constantly.

I’m pretty sure that more species will take to city life, mostly causing no problems to people. But I think I have probably underestimated the future impact of city gulls – which are taking over from city pigeons – and are likely to cause more and more summer-time injuries by attacking people. Local Authorities will soon be wishing that their docile city pigeons were back! If we don’t want a growing gull problem, we need to keep our streets very much cleaner and food discard-free, something we seem to find impossible.

Human greed knows seemingly few boundaries and it’s easy to get depressed when you witness the illegal wild bird trade first hand. Unless some of the worst offending countries start acting on their international responsibilities, it’s set to continue apace.

You have plenty of interesting stories to tell – are there any bird encounters/tales featured in this book that particularly stand out for you?

Many stand out, particularly those where I had personal experience such as a Parsi funeral or collecting eiderdown from nests. But one story that does stand out particularly is that of Honeyguides leading African tribesmen to wild bee nests. I was able to gather it from a N’dorobo tribesman in northern Kenya via an Italian ornithologist working there who translated his words for me! And next week I join them both in the isolated Mathews forested mountains in Kenya. So I will be able to follow Honeyguides with Robet Lentaaya, the tribesman concerned. It’s a practice that’s dying out.

What was special, too, was the information that he can follow three different Honeyguide species, each with a different call and different response call back from the tribesman. I can’t find any mention of that anywhere in the literature!

If a reader were to take one thing away from the experience of reading Life with Birds, what would you like that to be?

That our lives and theirs remain very strongly bound together, more closely than most people would ever imagine, even in our supposedly advanced western society.
