Torpor is an incredible strategy that continues to blow my mind🤯. Animals in torpor allow their body temperature to drop, slowing their metabolism and saving energy. In this composite thermal image of a blue-throated mountain-gem: left- asleep, right- torpor. 1/5
I have news! I just joined
@TIFRH_buzz
as faculty 2 weeks ago. It's a crazy change after 11 years of living in the US! But I'm super excited to work with students in India to study animals in the tropics, understand heterothermy better, and help shape Indian ecology!

Happy to answer questions about this fellowship that changed my life :)
To people looking for an independent postdoc fellowship, apply for a Rose fellowship at the Cornell Lab of Ornithology by Oct 4! I've been on it for 2 yrs and I 💕 it. And no, you don't have to be a birder🙃. Happy to answer questions!
@CornellBirds
I am so excited to have been selected to be among this cohort of truly incredible women. We've met twice now and 🤯. The things that can happen when women support each other and receive support ❤️❤️.
We are delighted to announce the 2022 Leading Edge Fellows!
45 superstar postdocs doing cutting-edge research in biochemistry, cell and developmental biology, neuroscience, microbiology, bioinformatics, bioengineering and more!
And this is the same bird later at night in deep torpor- it's practically invisible in the thermal camera because it's almost the same temperature as the outside air! The bird is also barely breathing- I promise this is a video, same speed as the previous! 😃4/5
This is really cool, because it means birds, and not just mammals, under natural temperatures, can fine-tune their body temperatures in torpor. Really makes me wonder what's going on inside them that allows so much flexibility 🤔. This is a sleeping black-chinned hummingbird: 3/5
My last dissertation chapter, on shallow torpor and a heterothermy spectrum in hummingbirds, is puuubbbliiiiiiiiiisssshhhhhheddddd!!!!!! Let me know if you want to read it, I'll send a PDF! And there are some exciting articles covering this work coming out soon ❤️

@nushiamme
and colleagues have found that
#hummingbirds
can use shallow torpor, in addition to deep torpor, to conserve energy overnight, which allows them to emerge rapidly from the mini-hibernation when threatened
In our paper on
#hummingbird
heterothermy in
@J_Exp_Biol
, we show that hummingbirds are capable of a range of body temperatures in torpor. Not just normal sleep (temp ~110F / 40C) and deep torpor (~50F / 10C), but an in-between state we call shallow torpor (~80F / 26C). 2/5
Here's a time lapse Erich made of a rare deep torpor event by a nesting female. These deep torpor nights were just two of 108 nights that we had cameras on females at nests.

Reminder (I'm so looking forward to this), this is tomorrow (Thursday)! It was strange preparing for this, because it's my dissertation work, but I had to restructure it completely! I defended Dec 2018 but article revisions added so much to it.

campus
Above is the call for 2024 graduate student applications. Students do lab rotations in 3 labs before choosing a PhD lab. If you're interested in the physiological ecology of birds, or know students who are, let me know! I am not actively recruiting but am happy to chat.
We are organizing a
#torpor
symposium
@SICB_
2023 in Austin, TX! Submit your abstracts for a complementary session talk if you work on daily torpor-adjacent questions! I'm very excited for this symposium 🥳
There is an exciting lineup of symposia at this year's meeting. Most symposia also have complementary oral and/or poster sessions. If your research aligns well with any of these research areas, consider contributing to those complementary sessions.
Most of the emails I've been sending and receiving now start with "Sorry to get back to you late" Maybe we should all just stop apologizing and know everything's crazy for everyone?

@nushiamme
allometry of daily energy expenditure shows hummingbirds increase efficiency only slightly with size, likely because of all the hovering!
If you're a female

Hummingbirds:
- Eat every fifteen minutes.
- Eat the size-adjusted-equivalent of a can of soda's worth of sugar per minute
- Could die if they don't eat for two hours.
- Make tiny magical nests made of spiderwebs.

This is a really useful tool to get a sense of some journals possibilities, ranked by relevance and impact factor and similar articles. Just need to enter a title/abstract!
I was honestly feeling a little bleh and headachey with the cloudy weather this morning, but talking to kindergarteners and first graders about hummingbird cleared up the bleh very quick 😬😬. These littles ask

Question for you, what is the range of body temperatures a hummingbird can go to and still survive? Once you take the poll, head over to the link below to find out!
Thank you

@GreenGirrl
So far, passerines don't seem to be able to use deep torpor (i.e. more than 20°C body temperature drop). Some species- like chickadees and pigeons and drop their temperature in the range of 6-12°C to use more shallow torpor though! I'm not sure if warbler torpor has been studied!
