Prehistoric trackways, woodland, and a bird hide overlooking a lake: these are some of the reasons why one of my favourite spots around here is the Decoy Lake at the west end of Shapwick Heath.
I initially came across it some years ago on my first trip here – a futile quest to see otters – but even then realised that this particular lake is a good spot for the charismatic great crested grebe. The various routes to it are attractive, either through deciduous woodland or alongside a large reedbed. The woodland also contains a re-constructed trackway that was built around 1500BC, but next to the lake itself is the site of an even older trackway, dated by analysis of the tree-rings to 3607BC. This is the Sweet Track, named after the peat worker, Ray Sweet, who discovered it in 1970.
This year I’ve decided to focus particularly on this patch, and particularly the grebes – partly because my days of chasing rarities are receding 🙂 and partly because it is (for me) a new focus for the birdwatching.
I hadn’t quite realised before that the decoy lake is a good site for wintering ducks. Early in January there were large numbers – surprisingly many shovelers (characterised by their massive bills), and a few of the elegant pintails. The next time I went, towards the end of the month, I was surprised to see very few ducks and wondered where the others had gone. An hour or so later, as we neared sunset, small flocks of shovelers and teal splashed down, and the overall numbers were closer to the previous visit.
As for grebes, though, things seemed a bit forlorn. Last year around February I counted up to seven adult great-crested grebes, so when I didn’t see any at the start of my first visit in January, I was a bit concerned. Eventually one emerged from a reedbed in the middle of the lake. I was distinctly relieved! I later saw a second one with different plumage. A couple of weeks later, though, there really was only one – but this one (right, with gadwall) was still in winter plumage, unlike the one below, photographed on the previous visit ten days earlier, had plumage which was more advanced towards breeding. I wondered what had happened to the other one.
I began to hope that the one or two grebes wintering here would be joined by others migrating in from elsewhere, otherwise there’d be much less to photograph and blog! I’d have to wait to February to begin to find out.
