Another one is the phalarope, a species of shorebird that migrates across North America, nests in the tundra of the Arctic, and spends the winter in South America. The Red-Necked Phalarope, Wilson’s Phalarope, and Red Phalarope are the three distinct species of phalaropes. The gender roles are reversible in phalaropes. Some even have colouring that is inverted. The female will pursue the male while defending a territory. After mating, the female lays one egg, then departs, allowing the male to incubate it and rear the kid until the cycle repeats again with the next male in the colony.
