After a good few years visiting the Sewage Works I have reached the above total with the arrival of 3 Garganey briefly, it was one bird I didn’t expect to see here, despite the huge numbers of wintering Teal.
Found by Richard, they were in the big tanks on the right at the end of the path and initially comprised of 2 Drakes, both displaying. However both lifted off, when an unseen female flew towards the river from nearby to them and all 3 were last seen heading up river.
No doubt part of the influx of them coming into the UK, they finally got me to seeing 150 species on the site.
I also caught up with the Siberian Chiffchaff again, initially located as it was singing, totally different song to repetitive Chiffchaff which was what got me onto it in the first place, hearing something unknown tend to stop you in your tracks.
