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

Much cheaper also. No need to walk around with a large lens or anything, just an extra casing for your phone. Makes it more convenient as well.

[Niels Goulem @NGoulem]

There's no doubt for me: a phonescoped video of a bird, even in the simplest of situations, takes you so much closer to it than any still picture could. For the same reason people now mostly take videos of their children, I'll mostly take videos of my birds.

@mrtnrey Hey Maarten, tot welke hoogte is dit? Heb onlangs nog een report gehad van een "big insect strike" op de windshield op 16000ft

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!

@mrtnrey Opletten Maarten, seffens wordt je nog een vogelkijker! Dat is levenslang hé

[Niels Goulem @NGoulem]

@pancartazoss @writebikerepeat Quite the opposite, the groups are incredibly scattered and keep on coming for ages, even as people are leaving. As the groups are smaller you have lots of time to see who's riding by and cheer

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

@George_NRBO No belgian ring on it?

[Niels Goulem @NGoulem]

Ringed in 2008, still flying around.

Ringed in the port of Zeebruges, but hasn't been seen there since 2014. Spends its time in Koksijde (BE) with occasional holidays in Vlissingen (NL). 109 sightings along its life, last one in October, same place.

Have a nice spring KN•AT

1510, 200 years before Linnaeus, 350 years before the first porro prisms were invented but this guy knew his birds

This painting is over 500 years old, but looks like it could have been made yesterday.

It might seem like an acid trip - it's actually the greatest warning about sin ever painted... (thread) 🧵

15242 roosting gulls (mainly black-headed with common, herring and caspian) forming a cute little heart at the CCB quarry (Tournai) on Saturday evening. Just before a Eurasian eagle-owl started singing openly from the top of a poplar. Quite an atmosphere!

@TomBovens Leuk spelletje. Ik zie 8 grielen?
