Disadvantages of Bird-Pollinated Flowers
There are some disadvantages of pollination by birds in plants which are as follows.
- More energy requirement: More energy is invested in the case of bird pollination than bee pollination.
- Requirement of more nectar: Bird-pollinated plants produce more amount of nectar and are larger to accommodate the birds.
- Requirement of more flower protection: Bird-pollinated plants have to invest more in flower structures so that they can protect their nectar from scavengers.
- Less differentiation: Birds tend to avoid flowers that are energetically unprofitable for them. Thus it can limit the pollen to a set of seeds in small populations.

Some birds that help in pollination of flowers are hummingbirds, spiderhunters, drongos, orioles, sunbirds, honeycreepers, and sugar birds.
