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 new paper published today in Current Biology shows that immediate international cooperation is needed to conserve the eastern North American monarch butterfly.

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.

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 [email protected] @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

This Gull was hanging out at the singles area on Kent Island. I'm flummoxed on this one. Maybe @liamtaylor.bsky.social can offer some advice! #GullOfTheDay

Nesting is progressing nicely on Kent Island. We already have one Savannah Sparrow nest with nestlings! These tiny babies will be ready to leave the nest in just 7 more days! @dmennill.bsky.social @ryannorrissci.bsky.social
