How do birds sense the magnetic field to navigate? The research field is slowly coalescing around a quantum mechanics mechanism described in the thread below. #Ornithology 🪶

Happy solstice ❄️ In the Northern hemisphere we have our shortest day of the year. In Nuuk the sun came up at 11:21 and will go down at 15:27 (3:27pm). How much daylight do you have for the solstice?

ARTISTS! I need your help! In collab. w/the Society for Integrative & Comparative Biology, I'm organizing a group of artists to come to our Jan. meeting! We're looking for artists to create based on what they learn at the conference. $1000 stipend. Application is V short! forms.gle/ah1i8KwNJinZ...

We churned through over 100 million radar samples to quantify the structure of migration through the airspaces across the United States: Just out in Ecology esajournals.onlinelibrary.wiley.com/doi/epdf/10....

Last night the sky danced like I’ve never seen before. It was wild. 🔭

Greenland Science Week starting off with a strong discussion on the importance of science for Greenlandic society and how to harmonize international and national interests for the benefit of society. #GreenlandScienceWeek #SciPol

Do songbirds align (migratory) flights to a specific part of their diel rhythm? In the snow bunting, nope, it’s flexible, but they keep a 24-h rhythm year round, even in Arctic summer. Includes a glossary of chronobiology terms relevant to ecology and migration 🪶 🧪 🌍 dx.doi.org/10.1002/jav....

There are forces in #nature that are at work that we don't experience or aren't aware of, but that are essential parts of the lives and spectacular numbers of creatures. For example, this from Ranjiangshang Ran and colleagues @pnas.org www.pnas.org/doi/10.1073/...

🚨 Master’s project! Curious how birds find their way? 🧭🐦 Analyze decades of ringing data to study abnormal migratory routes and uncover what these deviations can reveal about the mechanisms guiding birds on their journeys. Drop me an email for details! #ornithology www.vogelwarte.ch/de/wir/mitar...

The Danish national news published a collection of photos from seabird work in Greenland taken by Carsten Egevang. The pics are great illustrations of my previous haunts, and one of me looking particularly scruffy is buried in the bunch 🪶 #Seabird www.dr.dk/nyheder/vide...

I definitely wasn’t early to the Listers party, but I’m glad I made it. Can recommend to all birder adjacent and bird curious folks 🪶 m.youtube.com/watch?v=zl-w...

Nature does some wild stuff.

🚨NEW PAPER🚨 We've already shown mosquito infections vary by time-of-day, here we test whether infection of mice FROM mosquitoes vary in a rhythmic manner. We test this in untreated & drug treated mice as some fitness consequences are only apparent in stressful environments doi.org/10.1186/s130...

Circadian rhythms are pervasive and affect many different biological processes. Can engineering the circadian system improve agriculture across latitudes? 🧪 🌍 Natural populations may not have the same ability to extend to new latitudes bc of the lack of phenotypic plasticity or genetic variation

New review in PRX Life, where we propose a tangibility scale for the physics of social interactions, and highlight a few tangible examples - from dead fish “swimming” to efficient schooling, warm penguin huddles, and dry ant rafts. Written with the brilliant Chantal Nguyen 🐟🐧🐜 tinyurl.com/naet5tdh

First Arctic char—a beautiful fish #flyfishing on an evening break from fieldwork in South Greenland.

🇬🇱🇬🇱 Nunatta ullua pilluarit! Glædelig nationaldag Grønland!

A white-throated sparrow 🪶was seen for the first time in Greenland, and this was covered by one of the national newspapers. I was asked why this little guy ended up here. Short answer, no idea, but was quoted more eloquently. www.sermitsiaq.ag/kultur/spurv...

Hybrid zones, chickadees, and climate change - worth a read 🧪🌍#Ornithology

Does a marine mammal equivalent of eBird exist for reporting marine mammal sightings 🌍🦑

The most energy efficient flight occurs at intermediate flight speeds in a migratory songbird 🧪🪶

Migratory animals connect regions? Yes they do—also in the ocean 🌍🦑🪶 www.nature.com/articles/s41...

This looks like an exciting mix of ecology and biological rhythms. Looking forward to diving into this one #Chronobiology 🌍

Ornithology PhD opportunity in Canada 🌍🪶

Great opportunity if you’re a grad student interested in animal migration 🪶🧪🌍

Got a nice showing of a white-tailed eagle today in the fjord 🪶

Seems useful if you study animal behavior using videos 🪶🧪

Is an English or Danish edition of Arnaud Orain’s book, Le monde confisqué: Essai sur le capitalisme de la finitude, available? I just read an intriguing interview in @information.dk, and my curiosity is peaked on this interpretation of current geopolitics. #Economics #Geopolitics

The hilarious aspect of northern lights is that the most spectacular photos are meh in real life (still very cool though!). Like this pic was closer to… 1/3

Excited to share the latest publication from the group, which outlined how the bird brain detects light and the links to seasonal control of reproduction. @physiologyuog.bsky.social @sbohvm.gla.ac.uk onlinelibrary.wiley.com/doi/10.1111/...

Yes, insects also migrate 🪶

It’s a matter of efficiency… My first op-ed for @theguardian.com.

Best time of year (if you like vertebrates with hair and mammary glands)

It’s time. Place your bets.
