A Slavonian Grebe in the estuary was a surprise first for the year. The Warren previously held over 5% of the UK wintering population, but, aside from Herbert, an injured bird that was resident for 14 years until February 2021, this was only the third record since March 2017. It is also the earliest ever and just the fourth September arrival.
Also in the estuary 200 Curlew, 30 Sandwich Tern, 16 Wigeon, 10 Mediterranean Gull, 10 Ringed Plover, eight Dunlin and two Whimbrel.
Elsewhere 30 Swallow flew NE, with six Chiffchaff, four Blackcap and single Great Spotted Woodpecker and Kestrel on site.
Year list addition:
172. Slavonian Grebe
