Male Coastal Crested Wyvern's will gather in groups on cliffs to show off for females and potential mates. As the females fly around in the air above, the males will do their best to look like a stand out in the crowd. Occasionally, two males will squabble, taking to the air to chase their opponent into the water below. The males that stand out the best will find mates, leaving bachelors to make small bands for safety.
