There are many relatives to the bird this blog is named after in the ratite bird family (a family of large flightless birds). This group consists of:
The Moa (extinct 1500 CE):
The Elephant Bird (extinct 1500 CE):
(Elephant Bird Egg (left) compared to ostrich egg (right) compared to hand):
All the preceding were related to the beloved Struthio Camelus (Ostrich).
This has been your daily dose of ostrich education.
