You know you love birding when… you double-check that this young Great Black-backed Gull has all 12 retrices (tail feathers) as expected. Picture taken during a boat trip off Prince Edward Island, Canada on August 4th, 2025.🌿🌎🦉🦑

You know you love birding when… you find the molting pattern in the primaries of this adult American Herring Gull both 'very interesting' and 'aesthetic.' Picture taken during a boat trip off Prince Edward Island, Canada on August 4th, 2025.🌿🌎🦉🦑

Took hundreds of pictures this summer on Bylot Island (Nunavut, Canada), but only now had time to go through them. This molting Arctic fox giving a cute nose-lick while staring at me in the tundra is one of my favorites. 🌿🦊

C’est important d’être dynamique quand on fait une conférence… mais sans dépasser les limites ! La semaine dernière, j'étais peut-être un peu trop excité en parlant de mes recherches sur les renards arctiques dans un colloque à Churchill au Manitoba. #UQAR. 😅

We publish in Ecology 30 years of Arctic wildlife monitoring on Bylot Island (Nunavut, Canada)! Our long-term dataset tracks 35 species across 400 km² of tundra, providing rare insights into community dynamics, food webs, and climate responses. Open data for all at bitly.cx/OnOI2 🌍🦊🦉🦑 🧪🌿🌐

Canids seem to be the routine lovers, reusing their travel routes more than felids. This shapes hunting, encounters, and even disease spread. Insights from 1,239 GPS-tracked carnivores, including the Arctic foxes we track on Bylot Island 🧪🌿🌎🌐🦊. Read in the latest PNAS at bitly.cx/TxI2

Pictured is a male jaguar (Panthera onca) equipped with a tracking collar. William F. Fagan et al. tracked the movements of 1,239 mammalian carnivores, including 16 canid species and 18 felid species, on six continents. On average, compared with felids, canids displayed a greater density of trackways within their range and were more likely to reuse established trackways. According to the authors, the evolutionary differences in carnivore movement patterns could aid efforts to model encounters among carnivores, prey, and humans.

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. Our work will continue but at a smaller scale

Rebekah Tromble @rebekahtromble.bsky.social · Apr 18

NSF has posted an “update on priorities.”

They’re canceling all “DEI and misinformation/disinformation” grants.

And the guidance on how to fulfill the longstanding, legally mandated Broadening Participation requirement is utterly incoherent.

A look at the extent of sea ice in the Gulf of St. Lawrence this winter compared to the rest of the satellite-era. Each line here represents one year from 1979 (purple) to 2024 (white). 2025 is in red.

Map of Arctic: zacklabe.files.wordpress.com/2022/08/b203.... Data: nsidc.org/data/seaice_....

Line graph time series of 2025's daily Arctic sea ice extent compared to each year from 1979 to 2024 as shown with thin lines in colors from purple to white. This graph is for the Gulf of St. Lawrence region. There is large daily variability, but a long-term decreasing trend is visible during the melt season months. A seasonal cycle is also visible in this region.

Well the melt season is now rapidly underway 😳

Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. Additional scatter points show the maximum extents from 2000 to 2025. There is a long-term decreasing trend in ice extent for every day of the year.

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.🧪🌿🌎🦉🦊🐻‍❄️

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
