Wind or not, a sunny winter’s day is too good to miss, so I wrapped up warm and squelched through the mud around Wraysbury Lakes. In the car park, a Grey Wagtail hawked for insect life. Among the few ducks on the lakes were some Goldeneye, one of the winter specialities of the area. The Great Crested Grebes had most of the water to themselves, looking predatory with their sharp spear-beaks.
On the meadow, four Stock Doves got up – an under-recorded species if ever there was one, as people take them for feral or wood pigeons. A Green Woodpecker gave its ringing Plue-Plue-Plue call, really loudly: spring is on the way, honest! The Jackdaws wheeled and dived in the strong wind, totally at home. A Buzzard soared with barely a wingbeat, turning on well-rounded wings with fanned tail. Towards the end, the bushes thrummed with twittering Goldfinches.
But the best thing wasn’t a bird at all, but the Mistletoe hanging from a bare beech branch. Let’s hope it spreads.
Well, it isn’t every day one visits 3 nature reserves, but today I had a look at Hillingdon NHS’s Harefield Place LNR, London Wildlife Trust’s Frays Farm Meadows SSSI, and Denham Lock Wood to boot.
These are by London standards remarkably secluded and inaccessible, which is to say you need to know where to park and which way to walk, as there’s basically no indication on the ground until you arrive, and even the LWT website is misleading.
Whatever the reason, it’s a delight on a fine spring day to find woods alive with Chiffchaffs and Blackcaps, a pair of Greater Spotted Woodpeckers calling and chittering with excitement directly overhead (and visible in the still nearly-leafless trees), the Blackthorn in delicate white clouds of new blossom, and a Roe Deer skipping away across the meadow, stotting slightly and flashing its “I’ve seen you, I’m running away, and I’m faster than you so don’t bother” white rump-patch. It’s what zoologists call an honest signal, something that benefits both predator and prey. The predator is saved a wasted chase, and the prey gets away without hassle to live another day.
Canada Geese overhead
I walked in on the Golf Course path, a pleasant trek down the hill, past the lakes and along the muddy track through the willow woods. There are only our resident wildfowl at this time of year – Canada Geese, Egyptian Geese, Coot, Moorhen, Mallard, Tufted Duck, Mute Swan, Great Crested Grebe: presumably all breeding right here.
The track was studded with deer slots, and it was nice to have my “Roe Deer” slot identification confirmed with a broad-daylight sighting. Out of the woods, it grew hot, and I discarded coat and pullover.
An early Peacock butterfly
A few butterflies flitted about – Brimstone near the brambles, a Meadow Brown or two, several Peacock.
and a Vole Patrol poster
I met another LWT volunteer, Daniel, who it turned out was not only checking the local boardwalks, but had got up at 5:30 am to do the Vole Patrol on his local patch here! I said I volunteered at Gunnersbury Triangle, and he said he knew who I was, he read my blog (Hi Daniel!). We talked of Kingfishers and conservation and being bitten by small mammals. He asked me which group I particularly liked, birds, butterflies? I said dragonflies, but it was a bit early for them. Sure enough, a minute later, a damselfly flew past! I got my binoculars on to it but had no chance to identify it to species (Large Red is our earliest, but I saw no colour). Still, a distinct surprise so early in the year. Perhaps they are hatching earlier with the warmer climate.
On the way out, I passed a Vole Patrol poster. Huma, the small mammal expert in charge of the project, really can’t be getting a lot of sleep travelling all over West London like this and trapping every day.
I walked across to Denham Lock, an attractively rustic spot with a line of narrowboats, traditional wooden lock gates and a delightful lock-keeper’s cottage complete with teashop.
Denham Lock
A pair of Grey Wagtails flew about as if they owned the place, landing in the trees beside the canal, a few steps from where I took the photo. They must be breeding here too.
Most of my last few visits to Gunnersbury Triangle have been taken up with untangling a mass of fallen Willow trees in the mangrove swamp. One tree fell on the next, which fell on the next … and the whole lot were in sticky mud with a rising autumn water table, covered in ivy to boot. I lopped, chopped and carried branches and lumps of ivy away, getting happily hot, tired and dirty in the process.
Lopped Trunks in the Mangrove Swamp
Yesterday I wandered around with no tools other than camera and binoculars, and was rewarded with the sight of a Grey Wagtail, a Robin and a Wren hopping about and feeding in their different styles, exactly where I had been clearing.
Grey Wagtail: it is blurred as it was moving and wagging its tail
The wagtail was gobbling mouthfuls of grubs that it grabbed from the soft mud. It constantly bobbed and wagged its tail, displaying its yellow rump in the process. Could that be aposematic – is the yellow, in other words, a warning that the bird is distasteful? If not, why does it constantly flash yellow, even when no other birds of its species are about?
Today, I finished lopping the fallen Willow branches; as these last ones were over on the side, it was a cleaner and drier job. Then I joined in with a corporate group from Lend Lease, a well led and relaxed team … of property developers. They were incredibly pleasant to be with. The next surprise was at the hut when we all had a cup of tea: a nice Indian businessman in a suit came and asked us if his firm of engineers could use the reserve … for a group meditation. They stood about quietly and respectfully in a group, at least one person with hands pressed together in the ‘namaste’ position. We went on clearing and coppicing in the delightful autumn weather.
I got a small winged bug in my mouth; it released a pungent taste of cinnamon oils. Probably that is a chemical defence too: certainly a powerful taste, probably unpleasant in any quantity; but it was not bad in a one-off dose.
I ended my day sawing off some of the tree-stumps left over from the coppicing, together with one of the very capable and enthusiastic London Wildlife Trust trainees. It’s tremendous to see such good work going on in the reserve. And a piece of excellent news: a new warden has been appointed to manage work on the reserve, along with a West London warden who will be based here, but will have the massive task of keeping all the Hillingdon reserves from getting totally overgrown with hawthorn and blackthorn, among other things. So, suddenly, the place is full of life! Let’s hope we soon get our new visitor centre, we need it.
Conservation work with property developers; meditating engineers. You couldn’t make this up, or if you did, nobody would believe you. People say nature opens your mind, helps you feel relaxed. It does, you know.
