Designated as a species of Least Concern by BirdLife International (2009). The Capped Heron has a very wide geographic distribution. The global population size or population trends have not been quantified, but the population is not believed to be decreasing, at least not at a rapid rate.
Nonetheless the Capped Heron usually occurs only at low population densities. The relative abundance of the Capped Heron is assessed as "rare to locally uncommon" (Panama; Ridgely and Gwynne 1989); "uncommon and thinly spread" (Colombia; Hilty and Brown 1986); uncommon to fairly common (Venezuela; Hilty 2003); and uncommon (Ecuador, Ridgely and Greenfield 2001).
