Long-billed Curlew (Numenius americanus)
The Long-billed Curlew (Numenius americanus) has been identified as a focal species of management concern due to continuing declines of breeding populations, small overall population size, and threats to both breeding and wintering habitats across North America. Loss of grassland habitats to agriculture and development, particularly in the Great Plains of North America and eastern portion of the Long-billed Curlew's breeding range, appears to be the greatest threat to the long-term survival of this species.
Loss and degradation of wetland habitats and grasslands on wintering grounds is also a concern. Pesticides and other toxins, and disturbance due to off-road vehicles and recreational use of breeding habitats may also influence Long-billed Curlew populations.
