Most time spent birding, heart beating for migration. Convinced that many people could improve their existence by birding.

My most bizarre observation this year. On Öland for late autumn birding. Walked along the eastern coast this morning and heard a sharp call I couldn't place, eventually found a passerine high in the sky. A migrating Dipper! #BirdsSeenIn2025 #birdwatching @BirdLifeSverige

In the past five years I have ringed 34 Long-eared Owls. They are rare in Wiltshire so these totals are pretty amazing. We ringed this female in Jan 2023 and in March 2025 she was retrapped by a ringer in Finland - only the 4th 'LEO' ringed in the UK to be recovered in Finland!

Surveys by @CardiffOTT for @MARINElife_UK on @PelticSurveys provide more proof that thousands of Woodpigeons cross the Channel in Autumn: England to France. Many flocks visible on radar, all south, at 30mph speed, with 1.6k seen 15m N Alderney 31/10 & 10-20k 20m SW Guernsey 26/10

A sure sign of 'autumn' migration kicking in - the first juvenile Black-headed Gull on the beach here at #Filey this evening. Such beautiful birds, too....

So chuffed to finally see the stunning Black-browed Albatross sat on the cliffs and flying round, much better than previous fly-pasts.

Aquests dies està havent un pas brutal. Fixeu-vos que la freqüència d'observació de força espècies està a nivells de rècord, en especial la del papamosques gris: dades.ornitho.cat/llistes/MU…. A més, s'estan observant força individus de la subespècie balear. Estigueu al cas!

This male Egyptian #vulture is a breeder, but still it did these long (300-400 km) overnight flights. I am straggling to understand why @BIOEAF @MorantJon @lopez_pascual @EvanBuechley @louis_phipps

Yesterday morning, at first light, it was apparent there was an overnight increase in Bar-tailed Godwits on the Humber with 215 present, with only 24 the night before. After half an hour of preening and feeding, 150 circled up and flew out to sea into the sunrise #Vismig #OutEast

This is what a night of intense bird migration "looks" like on 2 wx #radars in NL. Imagine if we could monitor migration over all of Europe for research & applications like #aviation safety, reducing wildlife impacts of #windenergy and much more @EASA @EU_ENV @EuropeanMetSoc

Really feel for any Greenland White-fronts that are currently undertaking their migration to Iceland. From GPS tags, I can see at least one bird who has decamped to the Faroes and hunkering down. #Migration
