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.

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.

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: .

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!🧵.
