A horseclaw  is a large, two-legged flightless bird used as a mount for humans. A horseclaw has a large beak, vestigial wings and has large claws with three toes on each foot. Most horseclaws have dark to black feathers that cover their bodies as they would a normal bird. Horseclaws are very fast.
When Horseclaws mate, they mate for life. When one mate dies, the other instinctively knows about it and lays an egg. The gestation period of the egg to birth is unknown. Horseclaw young have fluffy white down feathers.
Female horseclaws often lay eggs when their mate is killed .
