Long-term trend

Status summary
Both BBS and WBS have small samples for this species. Because of the shortage of data, and the conflict between WBS and BBS assessments, the rapid decline indicated by WBS has not triggered a conservation listing. The decline shown by the WBS may reveal problems among birds on linear waterways during the early 1980s and late 1990s, while increases shown by the CBC and by BBS may suggest that wider populations (including small still waters) are healthy. In an analysis of nest record cards, Moss & Moss (1993) found that nests on ponds and lakes were significantly more successful than those on rivers and streams and that nests on rivers, subject to fluctuating water levels, experienced significantly higher failure rates through flooding than those on canals, where water levels are artificially maintained.
