#SICB2024 is over and we would like to say a big congrats to our 2024 Best Student Presentation Winners for DCB, David Cuban won the Mimi A. R. Koehl and Stephen A. Wainwright Award for their talk on feeding in sunbirds

Check out this science #dissemination article on our honeybee nectar-feeding research! Especially its connections to the importance of deepening our understanding of the details of the mechanisms for our broader understanding of ecological success:

Reaching deep: honeybees adapt their nectar extraction mechanisms to maintain feeding efficiency! Check out our data- and methods- rich paper on #mechanoethology and the importance of considering the actual behavior rather than accepting preconceptions!

Hummingbirds are famous for hovering but they'd take any opportunity to avoid doing so, and this reflects in their evolution! A new highlight of our research, in a nutshell: "Clinging hummingbirds have smaller beaks and bigger feet than do honest hoverers"

Most hummingbird-pollinated flowers droop upside down, so the animals must nimbly hover to access them, frantically beating their wings up to 80 times a second.
Yet some sneaky hummingbirds can cheat the system—with the help of their toes. scim.ag/3gH

Hummingbirds may seem noble hovering fairies that trade pollination services for nectar, but more than 20 times, short-billed species evolved long toenails to cling to feed or pierce flowers to steal nectar, while long-billed species must hover to feed.

Extremely enjoyable and fruitful work with @rkcolwell, @tf_rangel, @Euastrum, @Salty_Sparrow, and Diego Sustaita! Stayed tuned for the typeset version which will be fully open access! In the meantime feel free to access this unformatted version here: robertkcolwell.org/media_fil…
Tongues are the treasures that you rarely see because they are concealed inside the chest (mouth... confusing words with multiple meanings!), and there is so much to discover about these hidden gems!! Research from folks at our lab is featured here:

Since first evolving 350 million years ago, the tongue has taken myriad forms, unlocking new niches and boosting the diversity of life. #LongReads scim.ag/2NX

Cutting edge science doesn't have to involve the fanciest, most expensive technology.
In a new paper, Burke Ornithology Curator Alejandro Rico-Guevara (@ecophysicslab) shows just how much can be illuminated using a flashlight, a camera, and a tube full of sugar water.
Check out Alyssa Sargent's (a PhD student at our Behavioral Ecophysics Lab) work on a STEM curriculum and a "Hummingbird game"! facebook.com/burkemuseum/pos…

Our latest #hummingbird research is out in @RSocPublishing ! With @ecophysicslab @M_Araya_Salas Juan Parra and Gary Stiles. We studied how elevation and habitat structure gradients affect sexually dimorphic traits in the whole family, and we made the cover too!🧵
