That is, other than at feeders. They love sugar water and there are quite a number of feeder styles out there that cater to their feeding style. Their long beak is brilliant at getting down into flowers to reach the nectar, and they have a long tongue to lick it up, so these feeders mimic the flowers. Side note: They will also eat small insects, an adaptation that allows for survival when their are few flowers blooming such as after a big weather event like a hurricane.
Today I spent 30 minutes in a small garden in Troutville, Virginia, with lots of flowers and hummingbird feeders. And here are the pics.
