This species is listed as Near Threatened because it is suspected to be undergoing a moderately rapid population decline owing to the loss and degradation of its wetland habitats and continued hunting pressure and almost qualifies for a threatened listing under criteria A2cd+3cd.

|Range Description:||Actophilornis albinucha is endemic to Madagascar. It has been described as common or abundant in western and northern Madagascar, but is rare to absent in the east of the island (Langrand 1990, Morris and Hawkins 1998, Safford 2013). It has been noted that the species is becoming less frequently observed in suitable habitat (P. Morris in litt. 2010, L.-A. Réné de Roland in litt. 2012), probably indicating that a decline has occurred. This apparent decline is suspected to be on-going, on the basis of continued habitat loss and modification, as well as hunting pressure (del Hoyo et al. 1996, P. Morris in litt. 2010, L.-A. Réné de Roland in litt. 2012, G. Young in litt. 2012).|

|Population:||The population is estimated to number 1,000-10,000 individuals, roughly equating to 670-6,700 mature individuals.|
Trend Justification: The population appears to have become increasing rare in suitable habitat (P. Morris in litt. 2010, L.-A. Réné de Roland in litt. 2012), and is suspected to be in moderately rapid decline owing to on-going habitat destruction and degradation, as well as hunting pressure (del Hoyo et al. 1996, P. Morris in litt. 2010, L.-A. Réné de Roland in litt. 2012, G. Young in litt. 2012).
