New Citizen Science Blog Takes Flight
The citizen science program at the Cornell Lab invites you to be the first to preview a new kind of blog. Our new Citizen Science Blog is a blog inspired by the contributions and passions of citizen scientists—like you!
In its inaugural month, Citizen Science Blog will start with a look at everyone’s favorite winged jewels, hummingbirds! Can you match the speed of a hummingbird’s wings with your fingers? Find out in the interactive game, Beat the Beats. Plus, see how much liquid you’d have to consume to eat like a hummingbird. Check in often as new posts are added weekly.
