New paper: Is migration more dangerous during disease outbreaks? Long-term GPS tracking of rough-legged buzzards suggests highly pathogenic avian influenza substantially increased mortality risk during both spring and autumn migration. ➡️ vist.ly/5d8rb #MigrationEcology #Ornithology

Some country songs just ring true and reflect the happenings of real life. “…if I had a boat I'd go out on the ocean And if I had a pony I'd ride him on my boat” -Lyle Lovett
What a strange migratory divide. Do the populations even mix? 🪶 Many red-necked phalaropes breed on small ponds in West Greenland. Had no idea that they probably go to the western side of Central America. #Ornithology 🌍 www.frontiersin.org/journals/eco...
We had a wildfire conversation before heading in a field campaign this summer. Wildfires are a real threat.
Yes, Arctic wildfires are ‘new’, and sadly they form a positive feedback with climate change. Increasing wildfire activity is increasing the vulnerability of permafrost to thaw, accelerating the release of long-stored greenhouse gases. This is a feature, not a glitch, of the Anthropocene. 🔥📈🔥
Great opportunity for seabird research with the potential for immediate impact #Ornithology #PhDSky
Happy to announce a postdoc position with me and Jakob Strand, to work on data from the revamped Danish beached bird survey organised by DOF BirdLife Denmark. How many seabirds end up on Danish beached, where do they come from, and why did they die? #seabirds ecos.au.dk/en/about-us/...
🚨Very happy to share our new paper out in @currentbiology.bsky.social! 🦉 We show that barn owl colour morphs do not simply experience moonlight differently — they hunt differently under it. White morphs appear to turn bright moonlight into a hunting advantage. 1/3 #movementecology #barnowl #moon
Snow is falling down. May has passed by, becoming June. Good morning Arctic.
It has been an honour to work with the long-term data set from Kent Isl. After a survival paper (doi:10.1098/rspb.2024.2710), here is a mate-switching paper. Huge thanks to @liamtaylor.bsky.social on this one! A third one is under review. #seabirds #OpenAccess www.sciencedirect.com/science/arti...

Very excited to have this paper out in @animalecology.bsky.social Little is known about how Arctic wildlife responds behaviourally to windspeed. Therefore, we tracked GPS-collared muskoxen to quantify how wind speed and storm events shape their movement and habitat use. Read all about it here!
Fun to play a small part in this new work led by Tsevi Beatus and team: when the lights go off, honeybees simply stop flying and fall! (unlike flies and mosquitoes, which pull off smart maneuvers) Thanks to Richard Terrile in our lab for turning the lights off on bees, in the name of science 🐝🪰🦟

How much do you trust AI for bird ID? I’ve run all three pictures through Merlin. Wilson’s snipe is the top hit. Common snipe comes up too. Merlin doesn’t give a probability for the matches… Is the ranking due to more training data available for Wilson’s vs commons or is it real? 🪶 #Ornithology
🚨 Bird alert 🪶 Snipe in Nuuk, but which one?! 1st impression was common, but the underwing and birdNET of call suggest Wilson’s, though both are lower quality. Shadows reduced on underwing pic. BirdNET confidence was 8.7% and 1.8% on 2 detections. FYI snipes are rare here; both species possible
Still puzzled by this one 🪶 Can anyone help with the ID?

We’re looking for recommendations for an affordable camera to film slow motion of tadpole swimming. Doesn’t have to be crazy high tech or water proof, but decent frame rate and resolution to calculate velocity etc. Any suggestions would be highly appreciated 🙏🏼

Full annual-cycle tracking elucidates migratory activity patterns and stopovers in nightingales 🪶 🧪 🌍 #Ornithology (3rd try to repost…)
Small migratory birds cross deserts and seas as part of their annual migration. But how? Our new study shows how thrush nightingales do it: by flying night after night and stopping during the day, when they remain innactive🐦➡️(1/3) doi.org/10.1098/rsbl... @royalsocietypublishing.org #BirdMigration

Wondering how diel activity rhythms change across latitude? Check out Tash’s new paper. TLDR, Kittiwakes, a seabird, are flexible and range from 24-h rhythms at low latitude and appear to free-run or be arrhythmic at high latitude 🧪🪶🌍🦑
Delighted to see our paper out today in Proceedings B @royalsocietypublishing.org! We investigated how kittiwakes adapt their activity patterns across latitudes in response to the changing day-night cycle ☀️🌃 In short - we find that Arctic kittiwakes don't have bedtimes.. doi.org/10.1098/rspb... 🧵1/4
