No. Ostriches are in the bird family. Ostriches are very large birds which, along with the emu (an Australian bird), are the biggest birds. Ostriches aren't mammals because they don't have fur like other animals and and they don't have teeth like mammals have too. Nor do they feed their young on mothers' milk.

Yes, the flightless bird you're referring to is likely the rhea, which is native to South America. Rheas are large, flightless birds that resemble smaller ostriches, with long legs and necks, and a similar body shape. They are found in open grasslands and are known for their speed and ability to run quickly to escape predators. Unlike ostriches, rheas are social birds often seen in groups.

Penguins are known as the flightless bird, but ostriches are other common examples.
Kiwis, emus and cassowaries, together with rheas and ostriches, are flightless birds, or ratites. Ratites have wings but the bones in their chests do not have the capacity for flight muscles, which is what a bird needs to fly.
