Swaggersnapper

The swaggersnapper replaced its ancestor on the continent of Drake. It gets its name from the new mating rituals it exhibits. Mature males will stake out a 3 m wide "dance floor" on the beaches to attract a mate. Males will put on a show of flagging, strutting, and wagging; females who are impressed will join in their prospective mate's dance, until only a single female/male pair remain on the "dance floor"; pairs mate for life. It's also for this purpose that males will develop colorful patterns on their wings and tails to aid in their display; mated pairs will perform their original mating dance before actually mating and laying each clutch of eggs. These color patterns have also changed their hunting behaviors: males will use their color-spots to distract and chase prey into the direction of the waiting females.

Individuals live for 7 years. While couples mate for life, pairs of 3 or more will cooperate in watching over their young, using their swagger-displays to confuse and scare off predators. Chicks are also born with brownish feathers to blend into the sand; the feathers fade into a bluish tint as they age.
