Struthio – Ostriches
The heaviest, tallest and fastest runners among all birds
With the order name meaning “flightless birds”, Struthioniformes consists of ostriches two species – the largest living birds on our planet.
These birds lack a ‘keel’, a part of the breastbone where the muscles of the wings are attached. Their small wings prevent them from flying, but their strong legs and running skills more than make up for this.
These ground-nesting savanna runners also lay the largest eggs among all birds. And talk about chivalry; the male almost always does the egg incubation!
Ostriches are under threat due to hunting for their feathers and eggs, apart from habitat loss and degradation.
