Je moet het lef maar hebben. De hele wereld is slecht behalve extreem links. 😂

Iemand tips of goeie resources over welke compressie BS toepast op mp4 bestanden? Wou vandaag deze radarbeelden posten maar BS verminkt ze door extreme compressie waardoor ze heel blurry worden 🫤 Originele mp4 hier: ayco.duckdns.org/nlhrw2025041...

1/ 🧵Bird songs and calls are an important way that people experience the natural world. They’re also one of the key means of surveying bird populations. In this #BOU2025 talk I will review @btobirds.bsky.social research to explore opportunities and challenges of #bioacoustics in #ornithology

Great to see Whitburn #seawatching data used (through @trektellen.bsky.social) With just 78 Bonxies logged in over 1000 hours observation in 2024, it has been the worst ever year since regular documented seawatching started here. 😢 #NEbirding #seabirds

Impacts of highly pathogenic avian influenza on seabird populations in the North Sea are detectable in sea-watchers’ migration counts Sea-watching counts provided evidence of declines in abundance of four seabird species during autumn migration, which were consistent with the timing of highly pathogenic avian influenza (HPAI) out...

Like London buses, my second paper published in the space of a week! Working on the (substantial) impacts of HPAI on seabirds, it was fascinating to find that population changes in some of the hardest-hit species are reflected in @trektellen.bsky.social seawatch counts. dx.doi.org/10.1080/0006...

Great new paper #BirdStudy
