What is deference between cow and ostrich?

Cows and ostriches are fundamentally different species; cows are mammals and belong to the Bovidae family, while ostriches are birds and belong to the Struthionidae family. Cows are typically domesticated for milk and meat production, while ostriches are known for their large size, fast running, and valuable feathers. Additionally, cows are herbivores that primarily graze on grass, whereas ostriches are omnivores that can eat plants, insects, and small animals. Their physical characteristics and reproductive methods also differ significantly, with cows giving live birth and ostriches laying eggs.
