How to identify birds by their songs and calls

How to identify birds by their songs and calls

There are plenty of smartphone apps for this purpose but without knowing what you’re likely to see or hear software such as Merlin or Birdnet can mislead if used in isolation. I’m not an expert but birder and fellow Kent walker Dave most definitely is. I’ve never seen him use an app. He just stands in the middle of the path for ages building up an aural picture from the space around us. “Chaffinches somewhere in that oak 30 metres to the right; greenfinch behind us, maybe 200 metres, nuthatch flying to those conifers… look, there it is, mistle thrush down low …” I find it quite annoying to be honest. But it’s a remarkable display of skill, patience and knowledge built up over years.

What doing the odd walk with Dave has taught me is that it’s best to learn a few calls of birds you are likely to see/hear and then, once you are familiar with them, start adding other likely species. Some, robin, blue and great tits, blackbird, you can learn from the garden or park. Cuckoo is obvious and one you can hear this month and in June on the Ide Hill, Chiddingstone and Hever walks in particular. Greenfinch is very distinctive too and dead easy to pick up once you know its chatter and “wheeze” – similar but different enough to more common goldfinch. You hear it more in parks and gardens though than on the KWNL walks.

It took me ages to realise that wrens were incredibly loud and identifiable; I’ve got that one down now, along with song thrush, greenfinch, chaffinch, long tailed tits, chiff chaff, blackcap, coal tit, goldcrest, and most recently, nuthatch. I’ve no idea what dunnocks sound like, so I better give that a listen, and treecreeper too. Bullfinch is a toughie because you really have to listen out for their weird “rusty gate”-like whistle and toots. Yellowhammer is easy. To see one of these I recommend the hedgerows on the Polhill route, once down on the valley floor; Fackenden Down hedges; the Eastern Valley walk and the Chevening walk. A great one to listen for now is common whitethroat. These have arrived from Africa now and are filling our hedgerows with song; they sound a bit like their cousins the blackcap but less rich and burbling. There are loads of other, less common, summer visitors to tick off, which all may be encountered on a walk at KWNL – willow warbler has a lovely song, nightingale obviously, garden warbler… Cetti’s warbler is startlingly loud and a bird that sings disconcertingly close to you but from deep inside a thorny dense bush, so you can’t see it.

So, I’d say use a combination of memory and app to recognise birdsong. Use the RSPB site and British Birdsongs to learn two or three bird species at a time, then use one of the smartphone apps to record and analyse what you hear – having listened out for the birds you’ve tried to memorise. It doesn’t seem easy at first but pretty soon you’ll start recognising the patterns. After all, it’s just music in another form and the difference between a chiffchaff and a wren will soon be as obvious as between Dua Lipa and, say, Raye. Or Chaka Khan and Whitney Houston. Or Teena Marie and Cindy Lauper. Or George Benson and Philip Bailey; Luther Vandross and Maurice White. I could go on, and would quite like to.

Encounter with a kite

Encounter with a kite

Two weekends of truly muddy conditions have passed; both have been very mild and reasonably bright (well, the Sundays anyway) but with heavy rain overnight only the most hardy, dedicated walkers have taken to the squidgy, squelchy paths. Last week we splashed around the 3.5-mile version of the Knockholt Pound/Chevening route; today, with a bit less time available we took to that old staple the Downe walk, with a couple of variations. The final field once heading back to the village was a glutinous saturated sea of clay, as it usually is after heavy rain. Oh for the days when this was a wildflower and hawthorn meadow left to its own devices, alive with the calls of yellowhammer and skylark. The Downe walk has lost two delightful wildflower meadows in recent years – one to a scraggy looking crop rotation, the other to grazing by a non-existent sheep flock.

Anyhow, never mind, there we go. Let’s focus on the positives: bright skies, great colours, a sudden crescendo of bird song including skylarks after a silent winter, a Spitfire taking off from Biggin Hill – what a brill din! – and a few snowdrops to admire. Best of all there was some wonderful bird of prey sightings. On the Knockholt route we were checked out by a low flying red kite and were given a private buzzard show. At Downe this Sunday I’ve rarely seen so many buzzards gliding and soaring. A hovering kestrel joined the party at one point, while on the return leg of the walk, on the hillside above the golf course, a red kite seemed to follow me along, drifting, sideslipping and wheeling on the breeze. These incredible birds have only been regularly seen on these walks in the past 10 years or so. They are a most welcome addition – along with the buzzards, themselves a relatively new bird to this part of Kent in these numbers. On entering the final beech woods I heard a tawny owl call, despite it being only 2.30pm.

A Christmas trudge – then some fudge

A Christmas trudge – then some fudge

We chose Lullingstone for our Christmas morning walk. Well, I didn’t actually. It was the family choice, and a surprise one because I was, for once in my life, all for staying in and wrongly assumed my partner would be. I’m glad we did though: staying in all day and not walking anywhere is hardly ever the right choice, even with a turkey to roast and fudge to finish.

There’s no denying that in the mild, grey, mizzly, boring weather the Darent Valley landscape seemed to have lost a bit of its lustre. It felt as if we’d taken it by surprise – it’s usually ready for us and induces an inward gasp of delight as we get our first view of it. On Christmas Day it looked a bit bleak, a bit ‘meh’. It seemed to be saying, “oh it’s just them again – I can’t be bothered frankly.”

Fieldfare profusion

But on closer examination there was a lot to enjoy: huge groups of fieldfare (a winter thrush visitor from north-east Europe); a few chaffinch (relatively scarce nowadays in these parts) in brilliant winter plumage; loads of berries – haws, rosehips, elderberry in the main – and long-tailed tits flitting through open woodland. The profusion of berries was the attraction for the fieldfares. My regular Lullingstone kestrel did not appear, nor did the almost tame goldcrest I’ve encountered previously in Upper Beechen Wood.

Oh, that tree!

I’m often astonished at myself for not noticing things – I’ve been known to sit on sofas at home without realising they are brand new, turn on TVs that someone has just delivered and installed, and fail to remark on a room‘s entire renovation. I exaggerate, but it amazes me that I’ve walked past the extraordinary old oak at Lullingstone pictured below at least 200 times without really clocking it; a memory of it must have been lodged in my brain somewhere since childhood, but in the subliminal part. In a similar vein there’s an elegant art deco building opposite Brixton station that’s very familiar to me but it was only last week, on returning from the Ritzy, that I actually looked at it and saw it for what it was. I’ll never ignore it again, and the same goes for this incredible oak.

To be fair, there are several of these oaks at Lullingstone, mostly up towards the golf clubhouse in the west of the park (unlike this one). With some I’m not quite sure if they’re dead or alive. There’s one that you could actually hide inside. This one, which is maybe 300 years old, has a kind of elephant’s face embedded, is indicated on the map below. I’m going to try to keep eyes and brain a bit more joined up from now on. Probably means less daydreaming – let’s see!

Look to the light

Look to the light

January walks are all about timing. Things can appear dreary, muddy, dank and generally unappealing but with the right weather conditions the quality of the light can make everything right. Clear, bright, frosty days are definitely the best for a Kent hike at this time of year and despite all the low cloud and rain this month, there have been quite a few such days falling at the weekend. Well, a couple anyway. We’ve tried to make the most of it and walks at Cudham, One Tree Hill, Ide Hill, Hosey, Downe (despite the new fences) and Petts Wood have come up trumps. With a hard frost, like the one we found at One Tree Hill last Sunday, a lot of the mud freezes, which helps considerably. Such days can be good for a spot of casual birdwatching too with small birds often so keen to feed that they care less for human presence – I’ve enjoyed up-close views of goldcrest, nuthatch, coal tit and brambling this winter. But it’s a mysterious affair; sometimes there are no birds at all.

September

One of Earth Wind and Fire’s finest, but also a great month if the weather is half decent, as it has been. I haven’t been out walking much, due to work and various things, and when I have it’s been mostly very local. At Downe, on Sunday, our late afternoon stroll was rewarded by wonderful light and colour and a great view of a tawny owl (big one, too), gliding between beeches near the end of the walk. Below are some pictures from recent walks. Clear September days have a special quality.

Birds of Kent and Kentish birds

Most walkers will often ask themselves ‘I wonder what that bird is?’ at some point along their favoured trudge, before moving on none the wiser.

On my most recent walk (Shoreham to Eynsford, December 3, 2015) I was lucky to spot a little egret (instantly recognisable) at Shoreham, and later a troop of long-tailed tits followed me along the hedgerows beside the Darent.

Soon after this I came to a young tree with plenty of seed heads draping from its thin branches. There appeared to be no birds in it but I could hear the whirs, whoops and clicks of finches. As I neared, a never-ending stream of birds left the tree – incredibly there must have been at least 75 in there, goldfinches or siskins. Being silhouetted I couldn’t tell exactly what they were.

Now, my mate Dave would have been able to tell me – and in a pleasant non-anoraky style too. He’d also have known what kind of tree it was, what type of birds make that call, and deduced what species they were from what they were eating (if he was on form). If Dave had been there we’d have spotted and heard so much more, but I was on my tod, so apart from the usual jackdaws, robins, parakeets, various gulls, mallards and blue tits, I saw nothing else. But there are a host of exciting birds on these walks – from various owls to tiny goldcrests – and it’s worth knowing what they are, even if you never see them!

So with this in mind I invited Dave to write a page for this website, and here it is.

Buzzards, aeroplanes and wild flowers

Buzzards, aeroplanes and wild flowers

The bluebells are well and truly finished now we’re into June, but the meadows in this little pocket of near-idyll from Westerham to Eynsford are alive with wild flowers. The field adjacent to Down House is particularly spectacular as are the open grass sweeps of Lullingstone. I’m no expert on variety identification but there’s more to see than just daisies and buttercups – there’s pyramidal orchids, abundant cow parsley, cowslips, chalk milkwort, speedwell…

Cycling near Cudham recently I disturbed a large buzzard. Close up, the scale of this bird of prey is decidedly impressive, but what suddenly occurred to me is that, when growing up, it was unheard of to see buzzards so close to London. They were definitely considered birds of the upland wilds, not the suburban fringe. There’s clearly been a sharp rise in their population in recent years in these parts … I wonder if there’s a breeding programme nearby, or perhaps it’s that their persecution by landowners has stopped. Soon after this I saw two buzzards soaring over the valley between Downe and Cudham, closely followed by a red kite gliding at height from north to south. Again, sightings that would have been almost unthinkable up until 10 years ago.

At Downe Bank, on another cycle on a recent coldish evening, I saw my first ever badger in the wild, hurrying across Cudham Road ahead of me as I laboriously ascended that steep hill.

Red Arrows

On June 13 walkers in the area will be treated to the sights and sounds of Spitfires, Hurricanes and the Red Arrows, all flying at the Biggin Hill Festival of Flight. The air show marks the 75th anniversary of the Battle of Britain, and while a more modest affair than the airfield’s major International Air Fairs (until 2010), the event should prove a fitting tribute to those who fought against the Nazis from Biggin Hill. And walkers and cyclists in the area that day will get some unusual and exciting views of the planes as they manoeuvre for passes over the airfield.
