The Red-necked Phalarope shows reversed sex roles. The female is the more brightly coloured and holds the territory, while the male alone incubates the eggs and takes care of the young. The nest is placed on the ground near a tarn, well hidden in low vegetation, and the clutch usually comprises 4 eggs. The young are nest-leavers and forage for themselves shortly after hatching. Since the male alone handles incubation and care of the young, a female in a good season can mate with several males, which is unusual among Swedish birds.
