Horswell Ditch – nine months after excavation
With the weather forecast to deteriorate tonight, I squeezed in a ringing session this morning. Not the most exciting of days but pretty typical for the middle of June. Just 27 birds of which 7 were recaptures and one a control Reed Warbler. This has probably come from Slapton Ley. Wrens and Blue Tits made up the bulk of the new birds but these also included the first juvenile Chiffchaff and Sedge Warbler of the year.
Things were so quiet at one point that I strolled across to look at the new ditch. The water level has dropped recently, exposing muddy banks but vegetation is already re-establishing after last year’s excavations. There were four species of damselfly and dragonfly present and I spotted a young frog close to the sluice. This is the first amphibian I have ever seen at SML so it looks as though the hoped-for increase in biodiversity has already started!
Another fine day tempted me out again today to complete clearing the net rides. Ringing produced 21 new birds: 1 Blackcap, 1 Blue Tit, 2 Long-tailed Tit, 8 Reed Warbler, 7 Robin, and 2 Sedge Warbler. 16 re-traps included a further 10 Reed Warbler and 2 more Sedge Warbler. There were plenty of juveniles of the resident species knocking about and the first juvenile reed warbler of the year was ringed.
It’s been a while since my last blog entry, partly because of a week off waiting for my stitches to come out but mostly because I was struck down with a particularly nasty intestinal bug, which showed no sign of improving. Tests followed, then more tests, followed by bloods and x-rays before a diagnosis was reached two weeks later. Turns out I had picked up Giardia, a water-borne parasitic flagellate, which attacks the lower intestine, most probably caught whilst splashing through the mud and water at South Milton when clearing the net rides on my last visit. It turns out that David Walliams caught the same bug during his charity swim down the Thames.
Fortunately, things improved rapidly after a course of antibiotics although I’m not 100% even after three and a half weeks. Nevertheless, I felt fit enough to get to SML on 2nd June and face up to the task of clearing the net rides again. I started at the seaward end. These rides had been under a metre of water during the late winter but were accessible now and the soft young reeds only took about thirty minutes to clear. The net rides by the sewage treatment works were more problematic and were at risk of being swamped by hemlock water dropwort. It still amazes me how much bramble and willow can grow in a few weeks as well.
Anyway, I carried on clearing vegetation until my batteries ran out then set up a few nets at about 9am. This turned out to be surprisingly productive, with 68 birds caught and a reasonable variety: 3 Blackbird, 4 Blackcap, 4 Blue Tit, 4 Chiffchaff, 4 Dunnock, 1 Garden Warbler, 1 Goldfinch, 2 Greenfinch, 1 Great Tit, 23 Reed Warbler, 4 Robin, 11 Sedge Warbler, 3 Whitethroat and 3 Wren.
