Hummingbirds live life at a fast pace, wings a blur, tongue darting in and out of flowers at a frenetic pace, often 15 or 20 times a second. Only recently did scientists come to a more clear understanding of how these speedy creatures drink nectar. The tongue of a #hummingbird, which is forked, is compressed until it reaches the nectar. Inside the flower, it opens up to trap nectar in the tongue and to pump nectar up two grooves in the tongue. The findings could affect thinking about how flowers and hummingbirds have evolved together, since the shape of the flower, the composition of the nectar and the shape and workings of the tongue all have to fit together for the system to work.
