Drove 10 hours to Canadian Forces Base Trenton to catch a C-130 Hercules to Greenland & Ellesmere. Flight cancelled (plane needed for forest fire response in Canada). Drove 10 hours back home. Oh well, this is part of Arctic field work! Next year will be better. Picture: inside a Hercules (2024).

Just back from animal ecology field work on Bylot Island, Nunavut. Taking a moment to share this picture of me walking near one of our beautiful short-term camps (background=Baffin). Not all work was that glamorous; I’ll share more ‘usual’ moments later. Now heading to Alert, Ellesmere Island.🧪🌿🌎🦉🦊🐻‍❄️

L’Ile Bylot, en face du village de Pond Inlet au Nunavut. C’est là que je rejoindrai demain mes étudiantes de l’ #UQAR, déjà arrivée il y a un mois pour nos recherches sur la faune arctique.

Scientific American covered our #MovementEcology work on Arctic foxes a couple of years ago, beautifully illustrating their continental-scale dispersal across Arctic Canada, through islands and sea ice straits.🧪🌿🌎🦊🌐🦑🐻‍❄️ #wildlife. If interested, enlarge map below (with full reference to article).

I'll be heading to Bylot Island (Nunavut) in a few days to study Arctic fox movements and Arctic biodiversity. My students are already there. Watch the video to feel what it’s like landing in the snowy tundra around mid-June (helicopter sound included). Impressive. 🦊🧪🌿🌎🌐 #wildlife

Two lifers... First time using a parabolic microphone (Wildtronics + Zoom F3) and first time creating a spectrogram (Audacity + Raven). Song sparrow, of course! Rimouski (Québec), June 2025. 🌿🌎🦉🔊 #wildlife

Les recherches sur la biodiversité de l'Arctique sont fascinantes et cruciales mais coûtent incroyablement cher. C'est toujours un combat de réussir à les mener; je l'ai expliqué à la journaliste Matisse Harvey de Radio-Canada. Lire à lc.cx/EZlUw- 🧪🌿🌎🌐🦊 #uqar #wildlife

White-nose syndrome has very severe consequences for North American bats, yet it’s largely overlooked by the public because neither bats nor the syndrome make for attractive photos. Exciting new discoveries on the syndrome in the latest Nature (lc.cx/5QJ8kM) 🧪🌿🌎🌐 #wildlife

The Snowy Owl, Québec’s provincial bird, has just been assessed as Threatened in Canada. This species nests in one of the fastest-changing climates on the planet. I took this photo of a Snowy Owl chick in our Alert biodiversity monitoring area (Nunavut) during the 2019 lemming peak. 🌿🌎🦉 #wildlife

Problem solving

Sometimes you dig through your old pictures and find gems like this baby North American porcupine in Parc national du Bic (Quebec). We spent nights in the woods studying their ecology, and I learned that you CAN pet a porcupine—just make sure you’re going in the right direction! 🧪🌿🌎🦊 #wildlife

Action on the sea ice: An Arctic wolf chases away a polar bear while other pack members rest nearby on the sea ice. While not a rare event, it's also not a common one at our CFS Alert biodiversity study area, Nunavut, Canada. Picture by Richard Cayer, 20 September 2020. 🌿🌎🦑 #addMam #wildlife

Interesting how Arctic ecological monitoring can be biased toward warmer and less variable temperature conditions. I’ve added my CFS Alert monitoring site and fieldwork period to this insightful graph by @zacklabe.com. Plus, an Arctic hare. 🧪🌿🌐🌎 #wildlife

Just finished the 18 lessons of the newly-released, free online course thebullshitmachines.com, exploring the benefits and harms of ChatGPT and other LLM assistants (took me about 3 hours). I thought I knew a lot about generative AI, but this made me think deeper. 🧪

Excellente nouvelle! Je vais pouvoir demander à mes enfants de laisser leur téléphone... tout en continuant à regarder le mien! 🤣

La migration des oiseaux peut être spectaculaire. Allez faire un tour sur ma chaine YouTube pour mieux comprendre comment la migration des rapaces, des oiseaux marins et des passereaux (comme les parulines) est suivie au Québec. 🧪🌿🦉🌎 #wildlife www.youtube.com/@chaine-orni...

Can confirm that my NSF grant "How False Beliefs Form & How to Correct Them" was cancelled today because it is "not in alignment with current NSF priorities" Shocking that understanding how people are misled by false information is now a forbidden topic.
