Watching THE RHEAS
(Order Rheiformes)
In the New World the place of the Ostriches is taken by a somewhat closely related group of birds known as the Rheas, Nandus, or American Ostriches {Rhea).
They are confined exclusively to the pampas of South America and are readily distinguished from the true Ostriches by the presence of three toes, a feathered neck, and practically no tail, though they agree with the Ostriches in the absence of aftershafts to the feathers.
While there are numerous other differences in the skeleton and soft parts, it may be stated that the Rheas have the powerful legs and hence the similar tremendous speed of the Ostriches. Their habits, as will be recounted later, are also similar.
