Writtle Wildlife Watch, July 2015

Do you ever dread those newspaper articles which begin with the words ‘Research suggests that…?' As someone with a science background, I do take exception to the way the media is happy to cherry-pick research and quote it out of context just to make a headline. 
 
But just recently – and perhaps you saw this on Springwatch – there was a really nice national survey undertaken to establish the identity of ‘Britain’s National Bird’. Clearly this was simply a popularity contest as there were no constitutional, social or political parameters as such, so the winner’s credibility as ‘national bird’ might be challenged!

It was however, a nice exercise and the winner was….cut to faces of various candidates in TV cookery show style…..the Robin. No surprise there, but some others were very interesting choices. What caught my attention was that there were no fewer than three birds of prey (Barn Owl, Red Kite, Hen Harrier) which seems rather contrary to the message I sometimes hear about how concerned we all are (allegedly) about the impact of these birds on populations of songbirds. That argument is, of course, unbelievably weak as firstly, raptors are generally at the top of food chains and if populations of prey species decline, then so do the predators. And secondly, not all raptors predate other birds.
 
So today I am launching a new survey to find Britain’s Most Important Bird. And, as if by magic, I am delighted to announce the results are already in! In reverse order and with reasons for their importance, the top five are: 
 
5) Turtle Dove 
A bird which has declined by a staggering 88% between 1995 and 2012, most probably as a result of herbicide use in the arable enviromnent and the general intensification of agriculture. Now a real ‘indicator’ species of the health of our farmed environment. Farming accounts for about two thirds of the UK’s land cover.
 
 4) Bee-eater

'European Bee-eater' by Elogollimoh 
A species which has just started breeding in very small numbers in the UK, perhaps suggesting that our climate is warming to the point where our UK bird list may change irrevocably in the next few years. A real humdinger of a bird with a weird, warbling call. Even more staggering in the flesh than in the photos.
 
3) Hen Harrier
A hugely controversial bird due to its preference for the chicks of Red Grouse. This puts it into conflict with gamekeepers, with a very heated debate about the way we manage our upland areas being the result. And on going and fascinating situation which concerns not only a single species, but is about the future of entire swathes of our countryside….
 
2) House Sparrow 
Martha was the very last Passenger Pigeon. She died alone in Cincinnati Zoo in 1914. The extinction of her species was, at one time, considered an impossibility due to the fact they once numbered in their billions. Yet they are gone and unless we keep an eye open for all species, we risk losing them. The House Sparrow, once almost ubiquitous, has declined by 71% since 1977. Might it go the same way?
 
1) Nightjar

The final choice is a little off-the-wall, a bit like the bird itself. Yes, they are rare but that is not why the judging panel (me) chose it. It is because it is a bird which is full of mystery, not least due to the fact that it is only active at night. Legend had it that the bird stole milk from goats (hence the scientific name of the genus, Caprimulgus, or ‘goat-sucker’!) but the charm of hearing their churring call and watching their distant silhouettes on a warm summer’s evening is an experience never to be forgotten. The Nightjar represents something we are at risk of losing – a sense of wonder at the natural world.
