Came across this Eurasian Bittern in the last light of today. Although there’s plenty of water and reed on the patch there only have been 9 previous sightings according to @waarneming with the last dating from 2011. #patchgold #dpwc2024

2 new raptors for the #dpwc2024 in 2 days! Yesterday this W-T Eagle flew right above my head, but the real #patchgold showed up this afternoon when a RED KITE suddenly appeared right in front of my car. The first sighting in januari on my patch! @dutchbirding @PatchBirding

It amazes me the amount of tweets saying ‘2023 was the best years birding’ etc with no mention of the catastrophic declines in common migs! Has birding become about vagrants & nothing else? I enjoy the scarcities/rarities I found but the lack of common migs is far more worrying!

Gisterenochtend vloog er langs telpost Westenschouwen een heuse Kuifleeuwerik! Helaas als broedvogel in Nederland uitgestorven, en omdat de soort niet trekt zien we -normaliter- geen doortrekkers van elders. De vorige waarneming in NL was alweer 3 jaar geleden... #vogeltrek

Wat gisteren begon als een gewoon leuk ochtendrondje in de haven zoals Jonathan en ik zo vaak doen, veranderde toen Jonathan "Wat is da? Wat is da?" riep op een manier dat ik meteen herkende als "dat is iets spannend". We kregen vervolgens samen een BONTE ZANGER in beeld! WAANZIN

Rogue butterfly releases are in the news again. I thought it might be useful to write a thread explaining some of the science behind why this route to re-establishing species is so problematic.

The day started in the best possible way, watching all 4 skua species powering north past a Hebridean headland - absolute bucket list stuff, and every bit as good as I hoped it would be!

The Oslo (Fornebu) Hume’s Warbler is still going strong and has the company of 2 tristis Chiffchaff. This morning it was -16C with 15cm of snow but they are still alive!
The Hume’s and one of the Chiffs enjoyed the sun together this morning and also seemed to share body warmth.

In the wake of Lula's election victory, Norway is to resume its 'Amazon Fund' sending Amazon protection subsidies to Brazil (halted in 2019 under Jair Bolsonaro). $483 million in unused aid waiting to be disbursed noticias.uol.com.br/colunas/… @GeorgeMonbiot

One Bar-tailed Godwit, known by its band number 4BBRW, has beaten its own 2020 record for “longest non-stop migration by a bird”—flying more than 8,100 miles over 239 hours without rest. audubon.org/news/these-might…
