all types of humming bird drinks nectar
nectar
A Hummingbird drinks nectar, not pollen. As for how much nectar one drinks per day, I believe it is equal to (or more than) the Hummingbird's body weight.
The sort of flower a hummingbird pursues largely depends on the species of hummingbird. Each type has its own preferences and is also physically built for certain flowers. For example, the sicklebill hummingbird's beak is drastically curved downward, making it quite proficient at obtaining nectar from flowers in the family Gesneriaceae.
A hummingbird drinking nectar from a flower and inadvertently transferring pollen to other flowers is an example of mutualism because both species benefit: the flower gets pollinated, allowing it to reproduce, while the hummingbird gets food in the form of nectar. This relationship is mutually beneficial as both species rely on each other for survival and reproduction.
