"Bioacoustics infrastructure for innovative field studies of ecology and conservation of migratory birds." Thank you, Canada Foundation for Innovation & Ontario Research Fund, for supporting our grant application for new #bioacoustics equipment! With S. Doucet & R. Norris @ryannorrissci.bsky.social.
Inter-brood interval affects offspring survival and fitness, and reflects timing of breeding and female quality. Our new paper on inter-brood interval appears in the new issue of Ibis, led by Hayley Spina and our collaborative Savannah Sparrow research team. @bou.org.uk @ryannorrissci.bsky.social
Thank you, Nature Guelph, for the invitation to speak about our research on acoustic monitoring of bird migration. It was great to join such an engaged and excited group of birders for the evening.
Birds & Beers V was a big success! Thanks to all who participated, including student poster & club presenters, speakers Oliver Love & Ryan Norris, Nelsy Niño for screening "Mingoya", Natalie Emerick for emceeing, community partners for joining us, and Vortex Canada & Whiskeyjack Boutique for prizes.
How many #birds are killed by #cats in Canada? Between 19-197 million! This is the main result from my first chapter of my PhD thesis just published in Avian Conservation and Ecology. ace-eco.org/vol20/iss2/a...

Double brooding improves lifetime fitness. Our paper "Multigenerational fitness outcomes of double-brooding: a 30-year study of a migratory songbird" appears in the latest Behavioral Ecology: tinyurl.com/3hsyd42m. By @hayleyspina.bsky.social @ryannorrissci.bsky.social and our collaborative team.
I launched our latest Motus Audio recorder just outside Algonquin Park, with a generous assist from Motus collaborator @ryannorrissci.bsky.social. Let's see how many sparrows and thrushes are still on-the-move in mid-October.
I stopped at Henrietta's Pine Bakery in Dwight for Thanksgiving treats. Technically I'm always at Henrietta's, ever since the Google Street View Car captured me here three years ago. @ryannorrissci.bsky.social
POV: You’re visiting someone who REALLY likes Canada Jays for Thanksgiving weekend. @ryannorrissci.bsky.social
PhD position available to study the migration ecology and year-round demography of blackpoll warblers.

Why do only some Savannah sparrows raise 2 broods in a single season?🪶
Research by Dr. Hayley Spina @integrativebiology.bsky.social shows that levels of a hormone linked to energy use during demanding times may reveal which females are more likely to double-brood

You know, there is this thing in science where evidence accumulates to such a degree that it becomes accepted as fact. Way to go Ross McKitrick from @uofguelph.bsky.social. Proud to have you on board.

Our lab had a fantastic time at the Soc. Cnd. Ornithologists meeting in Saskatoon last week! Thanks to @sco-soc-2025.bsky.social and the organizers.
And congrats to Jelany Duali for winning best student talk!

Today at the Society of Canadian Ornithologists meeting in Saskatoon:
- Jelany Duali and Sarah Mueller, our Guelph collaborators, will present research on sparrow behaviour
- I will join the Motus roundtable to discuss progress with Motus Audio
@sco-soc-2025.bsky.social @ryannorrissci.bsky.social
Now that's some forward thinking! @uofguelph.bsky.social
Our new paper published today in Current Biology shows that immediate international cooperation is needed to conserve the eastern North American monarch butterfly.

Ha! Love this, Tess!!! Tell us the final poll numbers please….and also when the paper is out.
We've just won two grants! Both are under embargo, but some exciting plans will now come to fruition for bioacoustic studies of wild birds and whales in Canada and beyond. With my awesome collaborators @jaclynaubin.bsky.social @ryannorrissci.bsky.social and S. Doucet.
It's a wrap for our 2025 Savannah Sparrow bioacoustic field studies. Thanks to our sparrow collaborators and the Bowdoin Scientific Station for a great field season in the Bay of Fundy.

How loud is a sparrow? Our new project involves measuring the amplitude of Savannah Sparrow songs.
This is a team investigation with @jaclynaubin.bsky.social, @sdobney.bsky.social, @nelsyninor.bsky.social, M. Bygrove, N. Emerick, and our sparrow collaborators, with funding from NSERC.
What a great season!!

Farewell Kent Island! With an A+ Savannah Sparrow team I helped record songs of 34 males, find 36 nests, and colour band 29 adults & 18 nestlings! More to come as the season finishes. Sad to leave, but thankful to be part of this project!@dmennill.bsky.social @ryannorrissci.bsky.social #ornithology
I see the @dmennill.bsky.social hammer and the post-hammer but where is the pre-hammer? Maybe @liamtaylor.bsky.social knows??
Do they influence the quality of the Savannah sparrow recordings? Maybe that’s why you have that PVC pipe on the recorders?
What are those tubes for at the top of the microphone?
Today I launched my final Song Meter recordings of the 2025 Kent Island field season. I’m loath to admit that our field expedition is nearing its end.
Herring Gulls are now hatching on Kent Island. This makes our Savannah Sparrow research more treacherous; giant gulls dive-bomb us when we step anywhere near their offspring. #GullOfTheDay #TerrorizedSavannahSparrowResearchers @ryannorrissci.bsky.social @liamtaylor.bsky.social
I wonder if something has been beating up on the Kent Island gulls? This one looks like it had a rough night. Now that he’s here, maybe @liamtaylor.bsky.social knows? #GullOfTheDay
