Scrubland Hornface

The scrubland hornface split from its ancestor, the river hornface. It has left Bone River and spreads across western Darwin. It has grown to twice its ancestors size. While its top horns are still large is other horns have shrunk in size. This is due to sexual selection where females like males with larger top horns. Females have horns too but are much smaller. Juveniles do not grow their horns until they are adults so they must stick with the herd to avoid being eaten by predators. Like their ancestors, they use "tail-nostril" honking to communicate. This is important due to their poor vision. They live in herds of 25 to 50 individuals and spend most of the day grazing. Most of the herd consists of females and juveniles with an alpha male protecting the herd. Rival males will challenge the alpha male regularly in hopes to take over the herd. Thus only the strongest most healthy male will get to mate with the females.
