Population justification: Continental populations were thought to be declining by 2% per year between 1980 and 1996 (equivalent to 16% in ten years) (AOU 1998, Hill 1998); however data from the North American Breeding Bird Survey indicate that these figures were incorrect and in fact annual declines at a rate of 0.6% between 1980 and 2006 are more realistic (Morrison et al. 2006). This equates to a decline of just 5.8% over a ten year period. However, it appears that there are considerably more Long-billed Curlews than previously thought, with a likely global population in the order of 50,000-123,000, based on recent assessments, expert opinion and statistically based surveys (Wetlands International 2006).
Trend justification: This species has undergone a small or statistically insignificant decrease over the last 40 years in North America (data from Breeding Bird Survey and/or Christmas Bird Count: Butcher and Niven 2007).
