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.
Dear Kitty. Some blog 
Hummingbirds are my favorite I really enjoyed watching this 🙂 I have several plants and 5 feeders, I barely see them…one day as I was putting the clean solution backup I heard a buzzing sounds behind me, a little female could not wait for me to hang the feeder… so I stood there holding the feeder enjoying a up close look at these amazing little birds.
Thanks for sharing Kitty. Hugs

Yes, also in Costa Rica hummingbirds come sometimes to feeders not on their usual spots, but temporarily held by people.
