Morphological diversity in the honeyeater hyolingual apparatus and its relationship with nectarivory

Honeyeaters (Aves, Meliphagidae) are a speciose clade of nectarivorous birds, and there is immense diversity in the degree to which different species within the family rely on nectar. Honeyeater...

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: science.org/content/article/…

Watch these honey bee tongues act as either spoons or straws, depending on the flower

The bees’ versatile feeding strategies help them access nectar as efficiently as possible

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" x.com/NewsfromScience/status…

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

Some hummingbirds are flower robbers. Here’s how to spot them

Big feet and short beaks allow the birds to mooch nectar without transporting pollen

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. journals.uchicago.edu/doi/ab…

AbstractDifferences among hummingbird species in bill length and shape have rightly been viewed as adaptive in relation to the morphology of the flowers they visit for nectar. In this study we...

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: science.org/content/article/…

How the tongue shaped life on Earth

By specializing for catching, ingesting, and swallowing all sorts of food, tongues had dramatic impact on animal evolution

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.
