Some species have reversed sex roles: only the males take care of eggs and young, while females compete for males. After laying a clutch, females quickly leave their mate in search for a new partner. One of these species is the red phalarope (Phalaropus fulicarius), a shorebird that spends most of its time at sea, but breeds in Arctic tundra. Bart Kempenaers and his team studied a population of red phalaropes near Utqiaġvik, Alaska, the northernmost city of the US. In this video you see glimpses of this fieldwork which led to new insights into the polyandrous mating system of this species.
