Breeding conditions:
Our objective was to examine Red-necked Phalarope nest fate and habitat preferences on Niglintgak Island, NWT. The 6 km2 study site was at the mouth of the Mackenzie delta and consisted primarily of low arctic wetland. In 2005 we located and determined the fates of 33 nests. 64% of nesting attempts successfully hatched at least one chick. The vegetation surrounding successful nests was taller and primarily composed of graminoid with little mud relative to nests that failed. These results suggest that P. lobatus do not have preference for particular habitat features of nest sites within their home range but they are choosing home ranges that are different from surrounding, unoccupied habitats. Furthermore, concealed nests have increased success compared to nests surrounded by shorter vegetation and a greater proportion of mud.
