Still a bit quiet by the river in Otley but at least BHG 241H has finally turned up again.
The expected cold wind from the east will hopefully encourage a few more new arrivals for Christmas! 🎅

Black-headed Gull 239J is back at Yeadon Tarn. 😀
There were no summer sightings this year but in 2024 it visited Nordjylland, Denmark, so it is probably safe to assume that it has been there again.
🇩🇰 BHGs are creatures of habit! 🇩🇰

One of the Black-headed Gulls at Yeadon Tarn has a metal leg ring .

Black-headed Gull 2440 was at Yeadon Tarn, Leeds, today.
It was probably ringed by the Merseyside Ringing Group and further details will hopefully follow.
Maybe blown in this direction by Storm Amy? 🤔
I have emailed Peter Coffey.
