What do we know about avian migration clocks? More importantly: what do we have yet to understand in order to explain responses of birds to environmental changes? Learn more on link.springer.com/article/10.100…. Paper by Barbara Helm and M. Liedvogel.

1/5 📢 Excited to share our latest paper with you! Co-authored by Bart Kranstauber, Hans van Gasteren, Willem Bouten, Judy Shamoun-Baranes, and myself, we delve into the seasonal flight altitudes of migratory birds over the North Sea.

Heeft Jos Collignon toevallig naar Zembla gekeken, en daarna tijdens vragenuur naar reactie MinisterN_S? Er zijn aanwijzingen voor Parkinson, kanker en angststoornissen, maar pesticide waakhond Ctgb heeft tumoren 'weggeredeneerd'. Spannende lectuur: bnnvara.nl/zembla/artikel…

Huge numbers of insects migrating into Cyprus last week. Many dead, but Crimson speckled moths arrived alive and kicking 😊 Will they reach NW-Europe🤩 Prachtbeer invassie????

🦗📡 Whether you're into insects or just monitoring tech, don't miss this issue! A great collection, with two papers from the #GloBAM & #HiRAD projects exploring the use of radars to provide detailed data (intensity, timing, height, spatial scale) on insect movements!

So happy to be able to share the stories of insect migration on a huge stage this morning - Sky News ! These gorgeous little flies, butterflies, wasps, dragonflies etc. are so vital for our planet. They are pollinators, pest controllers, decomposers, nutrient transferers etc.

Ik deel hier vaker radarbeelden van vogeltrek, maar die van gisteravond van radar Den Helder (KNMI) zijn toch wel heel bijzonder: vogels wachten op de Waddeneilanden en in Noord-NL de schemering af, om dan massaal over steken naar Engeland, waar ze overwinteren of verder trekken!

Hi UK, here they come! Huge start of bird migration from the Waddensea westwards. Currently an bird migration traffic rate of 9000 birds per km per hour. Enjoy 😉

Come work with us - PostDoc Vogelwarte_Science - on characterizing insect migration 🦋🪲🪰 using vertical-looking radars 📡 Deadline: 31 January Please RT! my.jobalino.ch/job/en/6cd5025…

High altitude insect movement is not uncommon on radar, but intensities comparable with extreme strong bird migration (birdtam 8) in large parts of NW-Europe (21 june 2025, 12:30 local time), see flysafe-birdtam.eu/composite_trac… Judy Shamoun-Baranes, HiRAD, Jurrien van Deijk
