Generally, yes. The flower will continue to produce nectar as long as it is fresh and there is sufficient water at the plant roots.
No, they drink nectar from flowers
The drink nectar from flowers and eat insects for protein.
Yes they do drink natural flower nectar, mainly from flowers that have co-evolved to provide them with the kind of sugar and amounts of nectar they prefer in exchange for pollination services. Hummingbird nectar flowers are usually red, orange, or bright pink, shaped like a tube or trumpet, and produce nectar that is weaker then that of insect-pollinated flowers and contains a high proportion of sucrose (the same as white table sugar).

no hummingbirds only drink nectar.
Hummingbirds drink mostly sugar water from feeders. They also drink nectar fro wild flowers. They also need other protein and nutrients. They get these from eating small insects.
They feed on nectar from flowers (and hummingbird feeders)
Vertebrates that eat nectar include hummingbirds and some bats. Hummingbirds have an ability to hover at a flower, and a long tong that they can stick deep into the flower to lap up nectar. Bats that drink nectar at night seek flowers by their smell. Then they hover at the flowers, and use their tongues to lick up nectar.
Hummingbirds are the only birds that have so far been determined to drink nectar.
Generally not. Both hummingbirds and bees extract nectar from flowers. Hummingbirds consume nectar, but do not produce nor do they drink honey. However, if you put honey water in a hummingbird feeder, the bird will consume the honey.
Hummingbirds catch their food, mostly nectar from flowers, by hovering in front of the flower and using their long, specialized beaks and tongues to extract the nectar. They also catch insects in mid-air using their agility and speed to snatch them out of the air.
Hummingbirds drink nectar from flowers using their long, specialized bills and extendable, tube-like tongues. They hover near the flower and use their fast wing beats to stay in one spot while they feed. Hummingbirds also eat insects and spiders for protein and nutrients.
