Book Description
The primary over-wintering sites for North American breeding Red-necked Phalaropes are believed to be off the western coast of Peru, with migration along the Pacific and Atlantic coasts of North America, and through the continent's interior towards the California shoreline. [...] The drying of freshwater ponds and the expansion of shrubs and trees into low- and sub-Arctic wetland habitats, with a changing climate, is expected to have a significant impact on habitat quality and availability for the species. [...] DISTRIBUTION Global Range The Red-necked Phalarope is the most widely distributed of the phalaropes, with breeding records across the whole of the circumpolar sub-Arctic. [...] After crossing the Atlantic Ocean, passing south of Greenland to the coastal waters of Labrador, it followed the eastern seaboard, and crossed the Gulf of Mexico to the Pacific where it over-wintered east of the Galapagos Islands (Smith et al. [...] Unlike Red Phalaropes that are more abundant off Brier Island on the Nova Scotia side of the bay, Red-necked Phalaropes are more common along the New Brunswick coast, in the channels south and east of Deer Island, the ledges south of Grand Manan, and along adjacent northeastern Maine (Brown and Gaskin 1988).

Book Description
Species with unusual mating systems and sex role reversal are valuable for testing theories about sexual selection and the evolution of reproductive traits that have been developed using more typical species. We used the polyandrous red-necked phalarope to test predictions about biases in primary sex ratio, factors influencing uniparental incubation and the evolution of small egg size in multi-clutching shorebird species. Egg density differed with embryo sex, and despite females being larger as adults, egg size increased with male-biased clutch sex ratio. Males had higher incubation attentiveness with greater body mass and in warmer, drier weather, while early nest initiation and increased incubation load decreased attentiveness. We detected no direct effect of experimentally manipulated incubation load on behaviour, however a greater incubation load increased the probability of nest abandonment. Our results highlight the effect of environmental conditions on reproduction in this species, and the need to reevalute our predictions about the effect of polyandrous breeding systems on reproductive traits.
