Normally when I head out into the wilds I like to get to somewhere where there is little or no evidence of humans, my benchmark for a good place is the complete absence of human noise. And that’s not usually easy to do. But on this trip back in December I found myself in a place that was everything I’d normally avoid!
I was at the RSPB reserve at Rainham Marshes which is in that part of estuary Essex I’d only normally visit if I had to, but apart from that it was bordered by industry on one side, landfill on another, a motorway and the Eurostar trainline on the third side and the River Thames providing the boundary on the fourth, southern, edge. But despite my original prejudice it turned out to be a brilliant place to see some great wildlife and bizarrely it was actually enhanced by the hubbub going on all around.
On entering the reserve, just beyond the visitor centre a male stonechat was perched on a twig close by, and I like stonechats – they’re very smart birds – so I took it as a good omen that I would see lots more wildlife. And the little guy was indeed a harbinger of things to come. Despite its green conservation status and being a resident in the UK, I don’t see stonechats very often, so I was pleased to see this one so close by.
The terrain at Rainham is interesting. It’s a combination of marshy reedbeds, small lakes, grassy scrub and in the middle is a disused military shooting range which I think dates back to the world wars. But altogether it’s a little oasis of wilderness in the midst of the industrial devastation that dominates this part of the Thames estuary to the east of London.
The marsh harrier (Circus aeruginosus, Dansk: rørhøg) is a magnificent bird of prey which I see fairly frequently as they quarter the low lying fenland that prevails to the north and east of Cambridge and the occasional one drifts through over the fields where I live, and here was a female showing her prominent golden crown, hunting over the marshes at Rainham. This species of harrier is another bird of prey which was virtually driven to extinction in the UK but has recovered in the last 40 years, presumably as the use of DDT ceased. And in the foreground on the island in the lake were wigeon (Anas penelope, Dansk: pibeand), lapwing (Vanellus vanellus, Dansk vibe) an unidentified gull and what I think may be starlings.
May be there were so many species and numbers here because they were hemmed in to a small area of suitable habitat, but further east along the estuary, deeper into Essex, there are huge areas of tidal mudflats on the Thames and other river estuaries, so this could be the western extremes of that expanse of habitat. Either way, the diversity of the birdlife here on the marshes was remarkable.
I said further back up this post that the southern boundary of the reserve is the river Thames, and to make the point, beyond the dyke which provided protection from the coastal tides of the river, a ship headed out to sea…
