Champagne and forests

With my wine supplies and the Euro both at low levels it was time for a quick trip across to France to visit the Champagne region and beyond. Cruising along a French motorway is not the best way to build a good bird list.  A couple of White Storks heading north were the highlight in a rather barren landscape.  The countryside was one of huge open arable fields with little or no rough ground or weedy corners.  The cleaned and manicured environment appeared to have little space for birdlife other than pigeons and crows.  Into the champagne region, the vineyards above the arable land supported a few Woodlarks and Stonechats, whilst Serin and Black Redstart were a feature of the villages. Even birds of prey seemed very scarce; a few Buzzards, a Hen Harrier and a handful of Black Kites on the move.

The exception to this general impoverishment seemed to be the woodlands.  They were full of birds; several species of woodpeckers including Black and Middle-spotted, lots of Nuthatches, Short-toed Treecreepers, Hawfinch, Firecrests, Marsh and Willow Tits.  The ground flora was also rich; the abundant Wood Anemone and Cowslip seemed to be 2-3 weeks ahead of the UK.

Why should this be so different to my local woods where all the woodland specialities have dwindled to zero in recent times?  One obvious difference is that all French woodlands seem to be managed.  Stacks of fire wood are a ubiquitous feature both in the forest and throughout every village.  The French forest management is based on high forest of native species, with long rotations, small-scale felling and mixed age structures, in contrast to the UK forestry obsession with plantations of non-native conifers that damaged so much of our ancient woodland.  The French reliance on natural regeneration from ‘mother trees’ promotes a diverse woodland structure from saplings through to tall mature trees.  The woodlands also seemed to be wet; lacking the network of drainage ditches so obvious in many UK woodlands.

Although deer are present, they do not seem to be in large numbers, nor do the woodlands show any obvious browse effects.  Wild Boar are also obvious, or at least evidence of their foraging are everywhere.  The rooting activities of Boar are claimed to be beneficial for natural regeneration but may have damaging effects at high densities.  Shooting is commonplace and no doubt keeps numbers of both deer and boar in check.  Again by contrast, we have ineffective deer control in many areas and a blinkered view to allowing Wild Boar to re-establish in our woodlands.  My local ‘protected’ woodlands are sadly owned by the Woodland Trust who do little or no management but do promote open access.  Dog-walkers and off-road cyclists seem to be the dominant users.

Thinking outside the box

What does my job as an ecologist entail?  Well, I guess it can be summed up as ensuring the nature reserves I have responsibility for meet their objectives.  This would normally focus on the key habitat condition or species targets.  One other area of work that particularly interests me is the management of a reserve to enhance the enjoyment visitors will gain from it.  This may involve ‘tricks’ to pull birds or other wildlife close to viewpoints through habitat manipulation, or the provision of the viewpoint in the right location.  On most reserves, the default option for viewing is an observation hide with its standard rectangular ‘box’ shape and narrow shuttered viewing slots.  Surely it is about time we were thinking outside the box.

A year ago, I was fortunate to visit Varanger in northern Norway and meet Tormod Amundsen and Elin Taranger of Biotope, an architectural business with special expertise in birds and birding.  Their approach to birding architecture is new and inspiring.  To cut a long story short, Tormod and I decided to visit a number of sites in the UK in order to promote discussion about the way we view wildlife and how the design or form of a viewing structure should reflect its specific function.

In a hectic 10 days we toured from Norfolk to Somerset to Dorset to Yorkshire and to Teeside, discovering some great projects in development and hopefully inspiring a few more.  Meetings with birders at Minsmere, Poole Harbour and Flamborough Head were particularly enjoyable.  We even managed a few birds along the way; Bittern, Bearded Tits, Water Pipit, Black-necked Grebe, Great White Egrets, a million Starlings, Woodlarks, Spoonbills, Rough-legged Buzzard, Merlin, Pink-footed and Greenland White-fronted Goose.  Site by site, Tormod’s quadcopter and camera captured aerial images to help plan the projects.

So what is wrong with the standard ‘box’ hide?  Well, in some situations very little, but why should we expect one standard design meet all the needs of an increasingly sophisticated viewing audience?  We may need structures to welcome visitors to a reserve, some for close viewing, some for elevated viewing over a habitat or landscape, some custom-built photographic hides, some to get us out of the wind and of course some to reduce disturbance of wildlife, as after all, there is a clue in the name.  Do many hides reduce disturbance? Or do birds just get used to the presence of people in that particular situation?  Viewing screens are a particular bĂȘte-noire of mine. Most magnificently silhouette the observer against the sky from the bird’s eye view. Do you seriously think they don’t know you are there?

The habitat and the viewpoint should form a partnership, each complimenting the other.  This will often involve careful design and management of the habitat as well as carefully chosen viewpoint designs and locations that enable great views of wildlife and habitat. The form of the viewpoint must follow its function.  We need flexibility, diversity and innovation.  Thanks to Tormod, reserve staff and birders along the way, I hope we have generated a whole range of ideas; some of which may be coming to a reserve near you.

The Golden Wellies 2014

Another year of the RSPB’s internal competition to find the best passage wader site, The Golden Wellies, has come to a conclusion.  There are both league and knockout elements to the competition to test good wetland management throughout the year.  Monthly counts of waders are recorded; they have to be ‘feet down’ on a managed fresh/brackish scrape or flood (not tidal).

The Premier League champions are, yet again, Frampton Marsh (photo top). Frampton recorded 33 species, just ahead of Minsmere (31), Deane Valley (29) and Dungeness (29).  The highlights of Frampton’s year included Lesser Yellowlegs, Dotterel, White-rumped Sandpiper (photo above), as well as 4 Pectoral Sandpipers, 6 Temminck’s Stints and both Red-necked and Grey Phalarope.  Frampton had an average monthly peak of 5,018 waders of 25.6 species, compared to Minsmere’s 481 waders of 23.4 species. Snettisham records the most waders monthly – an average peak of 33,000 birds, but only averaging 14 species a month.

Middleton Lakes had a storming year, topping The Championship with 29 species (including Pacific Golden Plover, Pec Sandp and Temminck’s Stint) and winning the ‘most improved site’ prize.   They are promoted to the Premier League along with Blacktoft (29) and Saltholme (28).  Langford Lowfields (22), Ynys-hir (20) and The Reef (18) were promoted from League One.  Middleton Lakes and Dearne (Old Moor) again demonstrate that well managed inland sites can compete with coastal sites in terms of wader diversity and numbers.

In all, 43 species of wader were recorded during the year, with a peak monthly count across all sites of 106,021 birds being recorded in September.  Monthly peak counts included 10,682 Black-tailed Godwits and 481 Whimbrel in April, 14 Black-winged Stilts in May, 288 Greenshank in July, 125 Curlew Sandpipers and 98 Little Stints in August, and 14 Pec Sands and 38 Jack Snipe in September.

Lee Valley

46 years have now passed since I first started recording birds in the Lee Valley; each year with its notebook neatly stacked on the bookshelf.  Over that time I have seen 265 bird species in my rather arbitrary valley recording area that stretches roughly from Ware down to Walthamstow.  In roughly a third of these years I have attempted the traditional New Year list, over the years noting between a feeble 76 and a magnificent 90 species. This years total was a very reasonable 89 species.  Whilst the number of species recorded over the years has kept steady or even increased, the number of birds certainly has not.

This winters mild conditions (so far) are evident by a real lack of wintering wildfowl. Tufted Duck, Pochard and Gadwall are all remarkable by their absence. Four Smew were one of the highlights of the day, but this is a far cry from the 40+ peaks of the 1980’s. Likewise the 4 Goosander noted of the dozen or so currently in the valley is way short of the flocks that approached 100 birds back when we had proper winters.  Despite the mild conditions, 6 or 7 wintering Bitterns are present, one of which revealed itself for the list.

Raven made it onto the list for the first time this year, with 4 birds at Amwell giving a characteristic tumbling display. Others becoming ‘regulars’ in recent years include Ring-necked Parakeet, Little Egret, Peregrine and Yellow-legged Gull.  Caspian Gull would have been added to the list if I had bothered to stay longer watching the gull roost.

Finches and buntings have been difficult to find in any numbers in recent years but this year it is great to see that the Lee Valley Park have retained large areas of stubbles and wild bird crops around Holyfield Farm.  These areas produced 250 Chaffinch, 50 Reed Buntings, 40 Linnets, a dozen Red-legged Partridge, hundreds of thrushes and a Stonechat.

From top to bottom, the highlights were as follows:
Amwell: 4 Raven, Yellow-legged Gull, Marsh Tit, Woodcock.
Rye Meads: Jack Snipe, Shelduck, Pintail, 5 Chiffchaff, 3 Cetti’s Warblers.
Holyfield: Stonechat, Pintail, 4 Goosander, Peregrine, Little Owl, 21 Egyptian Geese.
Cheshunt GP: Bittern, 4 Smew, 6 Water Rail.

Girling Reservoir: 7 Black-necked Grebe, Goldeneye.
