State Ranking Justification [-]
The Spine-crowned Clubtail is known to occur in eight counties in New York State (Donnelly 2004, New York Natural Heritage Program 2007). Population estimates have not been made. This species is secretive in its habits, and it is probably more common than records indicate. Further survey efforts may result in the identification of additional populations or range expansions, and may enable population sizes to be estimated.
