So, a little more detail about their motion:

- While running, hive birds bend their elbows and swing them back and forth for balance, the same way a human would.

- They bent forward and kept their center of mass far away from their legs, letting them run at fast speeds.

- Their arms are long enough to reach the ground while bent, so when they lose balance, they can reach for the ground and gain balance back without stopping.

- While their tails are quite stiff, they can still swing them for balance.

- When performing demanding tasks, their air pumps activate and throttle up, giving them an increase in strength.

- Their advanced AI lets them move even with multiple limbs damaged or destroyed.
