Back in the office (since Monday, but too many emails). A huge thank you to the organizers @isbe2026.bsky.social and all participants. I heard some amazing talks about exciting research. And thanks Italy for the food, the scenery (see photo, enabled thanks to the conf daycare!) and the people.

2016: an entire week to create and record an animation from GPS data. 2026: 2 minutes with an LLM to write a script that downloads my data and creates the animation, 10 more minutes to make it exactly as I want. #ISBE2026 #movementecology #biologging #AI 🧪🐾🪶🌎
@isbe2026.bsky.social is only a week away! Time to get back on @bsky.app 😅 Who am I meeting there? What talks should I not miss? Here is a teaser for my talk 🪶🐾🧪🌎 #conservation #movementecology #ornithology #animalbehavior #migration
This new format makes the review invitation feel much less personal and much less appealing. I almost deleted it because I thought it is another Wiley spam. @bou.org.uk 🧪🌎🪶
There's a journal I really like and I was even lucky to publish in it. But, something in the publishing process there is wrong. Me and others had bad experiences, and here is an example from a recent publication. What can I do? Contact someone? Name them here on Bsky? 🧪🌎
Of course, I would love to participate in your very real conference that you so kindly sent me an invitation to. The fact that it is happening next week and you are still looking for key-note speakers is completely normal, and so are your highlights. How do you stop these #academic_spam emails? 🧪🌎
Would have been really interesting if that was the real result of the SDM.. Luckily, it was just a small mistake in my R code.
These amazing birds breed and roost in what can only be described as Martian Habitat. They find shade under trees that were washed centuries ago when the Dead Sea reached further north. Feeding seems to mainly occur in nearby agriculture fields
In 2014, a car hit a strange bird in the northern Dead Sea area. The driver found a dead Egyptian #Nightjar, and saw another one flying away. First observation for that area. Multiple efforts started - surveys, ringing, tagging - and a breeding population was discovered!
Larger than a blackbird, in one of the most populated areas in the world, but still unseen for who knows how long. A second paper from the story of the discovery of the Egyptian #Nightjar in the Dead Sea area was published recently. 🧪🐾🌎🪶 📷 Y. Wasserlauf #ornithology #conservation #ecology
Another touristic site with my parents, another cool #bird_behavior. This time, Mainau and its beautiful trees present a cool Nuthach. #ornithology
Took my parents to see the Rhine Falls today. They enjoyed the falls, I enjoyed other things enjoying the falls 🙃 #ornithology
A great thank you to the organizers of #BESMove2025! It was really nice meeting new and old friends, hearing about so many interesting studies and even enjoying nice weather that allowed me to see the local wildlife 😅. See you next year?
What a wonderful day at the #BESMove2025! Fascinating talks, great people, beautiful campus (see pic). Really excited to talk about the migratory movements of Steppe Eagles tomorrow.
First time in England (kind of)! Excited for the @besmovesig.bsky.social #BES #Movement_Ecology annual meeting.
How come I never heard of this amazing butterfly? Lesser Emperor Butterfly (I think..), changing colors from brown to purple depending on the angle of light. Beautiful! Southern Germany, Aug 2025
By combining #conservation and #movement #ecology, we were able to add another piece to our understanding of the effects of the #anthropocene on migratory birds. This was achieved thanks to a great team. Thanks everyone!
Human habitats, especially in the desert, provide predictable food sources that seem to attract the juveniles. But they also come with risks that the adult eagles avoid. This avoidance means that the adult eagles take detours around these habitats, and use less ideal wind conditions.
Using Integrated Step Selection we found something which we did not expect (really!): Adults avoided human-altered habitats, juveniles preferred them more than randomly available, and sub-adults just used what they had. Juveniles also used straighter routes with stronger tail-winds. But why?
How are human-altered habitats affecting birds' migratory routes? And what is the role of age and wind conditions? We tested this for an #endangered #Eagle authors.elsevier.com/sd/article/S... 🐾🧪🪶 @yaelbird.bsky.social @talavgar.bsky.social @currentbiology.bsky.social #conservation #ornithology
Got a paper published in early view in @currentbiology.bsky.social today! I'm to tired to write a proper post, so consider this a teaser :)
OK R, no need to be passive-aggressive, I know I'm asking for too much Error: [writeRaster] cannot write more than 65535 layers
"Why are you so happy to see this small brownish bird*?" I was asked during the first of a 4 day hike in the Alps. These high altitude habitats, plants, birds and other critters are amazing. Getting away from everything and celebrating life is important. *bird too small, in the pic: not-a-bird

Asked the same thing from DallE in January 2023 and today (May 2025) from sora. Here are the results for "A realistic painting of an Egyptian vulture playing basketball". I am sure there is no need to explain why I asked this, probably one of the most common requests
