What type of bird falls under the classification of a ratite?

The classification of ratites encompasses a group of flightless birds that are characterized by their flat breastbones, which lack the keel that is typically present in flying birds. Ratites include species such as ostriches, emus, kiwis, cassowaries, and, interestingly, penguins. However, within the context of this question, the ostrich stands out as the most representative example of a ratite.

Ostriches are native to Africa and are known for their large size, long legs, and fast running capabilities. They exemplify the evolutionary adaptations of ratites, which have developed in environments where flight is not necessary for survival, allowing them to thrive on land.

In contrast, other birds listed, such as parrots and hummingbirds, are not classified as ratites. Parrots are well-known for their strong beaks and highly social behavior, while hummingbirds are distinguished by their ability to hover and rapid wing beats. Although penguins share some characteristics with ratites, such as being flightless, they are typically classified separately due to different evolutionary paths and physical adaptations.
