I built a wildlife pond in 3 days! Can’t wait to see all the cute birds bathing and drinking, and to find out what new taxa I can attract! 🌱 #PondLife #Wildlife #Nature #garden 1/2

Clay-coloured Sparrows are hatching & boy are they tiny! These birds have a rapid tepro cycle: incubation 10-14 days, fledging in 7-10 days - before the young can fly! They belly out of the nest & scoot around on the ground bc ground nesting is so dangerous! 🇨🇦🪶🪺🐣🧪 @usaskartsci.bsky.social

I filed a complaint to the CBC two weeks ago about their news coverage (CBC News this Hour stated, completely falsely, that Iran had previously rejected demands not to build a nuclear weapon) and the CBC has actually already now posted a correction.

📖 This long term study spatially analysed decades of territory maps to identify all nontrivial instances of natal territory inheritance in first-time breeding Florida Scrub-Jays (Aphelocoma coerulescens) 🔎 Read more: buff.ly/sm6s37g

Bull #sharks may have far more complex family lives than scientists once thought. By analysing genome-wide DNA from sharks sampled over a decade, researchers uncovered strong genetic links between adults at the Shark Reef Marine Reserve & young sharks in nearby rivers: doi.org/10.1098/rsos... #RSOS

A surprise western tiger #salamander hitched a ride in the aged compost I had delivered for my #garden. Hope the lil guy can find a suitable habitat in the neighbourhood, as it wandered out of the garden when I was shovelling endless loads of soil. 🦎 #Saskatchewan #wildlife

Is there snow in the forecast? Sure, maybe a little. Is there a Swainson’s Thrush in the back lane, yes there is. Spring will come. The thrush assured me 😊 #birds

The inaugural Grieves Lab field season got off to a cold & windy start! We will be back out around #Saskatoon tomorrow in search of our study species for #research on how birds use smell to find and attract mates and avoid parasitism 🧪🪶🇨🇦 @usaskartsci.bsky.social @usask.ca

Bird banding tells us a lot about bird populations & is an important tool in biology research. Banders require extensive training & permits before being granted the privilege of working with these amazing taxa! White-throated Sparrow, Dark-eyed Junco, Chipping Sparrow, Purple Finch 🪶🇨🇦 @usask.ca

Birds are probably the world champions at breathing. They can extract up to twice as much oxygen from air compared to mammals. Their respiratory systems take up 3-5 times as much body volume as those in mammals of similar size. And for good reason—flying high requires extreme ways to breathe. 2/6

Artificial light emissions at night increased by around 16% globally between 2014 and 2022, according to research in Nature. The study presents maps of night-time light changes, which help to reveal the intricacies in human light footprint across the globe. go.nature.com/3PZ2DVx 🌍🧪

Every day there are new announcements from the Canadian federal government gutting science programs. I was just notified that the National Boreal Caribou Knowledge Consortium (NBCKC) is dead. Terrible shame to do this at time when boreal caribou are in real trouble.

Well this is fcking crazy. Work from @msbbirds.bsky.social and others found that Black Metaltail hummingbirds can drop their body temperature down to 3 °C (37 °F) during torpor. 🤯 Turns out birds aren't warm-blooded after all! royalsocietypublishing.org/rsbl/article... 📷 Steve Juhasz

I had the privilege of meeting Kirsty Duncan back in 2017. She was warm and sincere. She was our first and only 🇨🇦 Minister of Science who was a trained scientist. She consistently worked for positive meaningful change in all her government roles. Condolences to her family and friends.

My annual "DO IT!" encouragement post! Selfishly, my time on CSEE council was the highlight of my PhD, it opened doors and opportunities that research alone did not. And I think we accomplished some good things for the society! 🧪🌎
