Twilight birding

On Tuesday 22nd October, after work with the light fading I visited Corton ORT and was immediately apparent there were a lot of Goldcrests present and I must have seen 50+ Also seen were 5 Robins and 5 Song Thrushes and in one small group of Crests and intriguing white bellied bird seen very briefly (Firecrest/ Ybw?) Also seen was a Chiff- Chaff. Nothing really seen at Corton Old Sewage works, but the light was fading rapidly with the sun setting at 5.50pm, maybe my last after work (5pm) birding for the year. Pity because the prospects of saving what has been a dire autumn seem slim.
