Marsh Ride in December 2022

It’s not all about the ringing for me at South Milton Ley. There’s a lot of management, which goes on behind the scenes. Today representatives of Devon Birds and the Devon Wildlife Trust met in the car park at South Huish Reserve, together with individuals with monitoring expertise, to discuss collaborative working. I was invited along because of my involvement in the previous management plans but had little to contribute other than things which had already been documented.

When the group set off to walk along the coast path from South Huish to South Milton Ley it was my cue to slope off. I had work I wanted to do and, as it was too windy for nets, this presented the perfect opportunity. The 48 metres of Marsh Ride can be very productive for birds during the breeding season and migration periods. Too wet to traverse safely, except during last summer’s period of near drought, I had laid new boards along the length of the ride in the summer of 2017. Despite my best efforts, a mat of turf had gradually encroached on the boards since then and was threatening to completely engulf them, making access increasingly risky.

I had been aware of the issue for some time but the ride has been inaccessible throughout this winter due to high water levels and the access bridge being underwater for long periods. Nevertheless, during my previous two visits, I had managed to clear most of the boards in 10-minute slots between net rounds, piling the turf into multiple heaps along the length of the ride. Wet turf is surprisingly heavy and the freshly cleared boards, with a layer of wet sediment on their surface were like a skating rink. By today, the boards at the northern end of the ride were completely dry and the piles of turf more manageable. The southern end remains underwater but turf is less of an issue there because of this.

The northern end of Marsh Ride – now clear of turf!

To cut a long story short, the ride is as clear as it’s been for the last six years, the boards are all visible, making access considerably safer and, flushed with success and not yet completely knackered, I decided to do a bit of work on Crest Ride at the eastern end of the ringing area. This is my second 48m net ride. Much less productive than Marsh Ride, it tends to catch mostly resident species but is good for Crests and Redwing in the winter, although anything can turn up. I had used it quite a lot in the early winter as it always remains accessible. One or two of the wooden posts anchoring guy ropes to the mist net poles were beginning to rot at their bases and becoming loose.

Fortunately, from my point of view, the National Trust had forced Devon Birds to replace the perimeter fencing at South Huish Reserve. Many of the original fence posts were in excellent condition and Nick Townsend had retrieved these and made some available. I’ve only hammered in two so far, with a couple more to do there and at Footpath Ride. Hopefully, I’ll get these done on my next visit before the ground dries out too much.

A drop in the wind strength allowed me to get in another day’s ringing. Chiffchaffs dominated the catch as usual with 27 trapped including 18 new birds. 42 birds were processed, with today’s highlight being the first Reed Bunting of the year. Totals: 1 Blackcap, 27 Chiffchaff, 2 Dunnock, 2 Firecrest, 3 Goldcrest, 2 Great Tit, 2 Long-tailed Tit, 1 Reed Bunting, 1 Robin, 1 Wren.

It still amazes me that one small sewage works in south Devon can support so many wintering Chiffchaffs. This winter’s total is now up to 225 different individuals trapped. Based on the increasing ratio of ringed to un-ringed birds as the winter progresses, my simple capture/recapture model is currently suggesting a total population of over 400!

Chiffchaffs were everywhere at South Milton Ley yesterday, but they were dispersed around the perimeter of the sewage works and feeding in pretty well every sunlit clump of brambles in adjacent hedgerows. This, combined with a not entirely favourable wind direction and the nets also sitting in full sunlight, was not a recipe for a large catch. Nevertheless 43 birds were processed, including 31 Chiffs. This raises the winter’s Chiffchaff total at SML up to 177 individuals, including 18 returning from previous winters!
