Conservation Status

The IUCN considers Ocellated Antbird to be of Least Concern, due to its large range and reasonable population size. Though the population is declining, the rate of decline is not sufficiently steep to constitute Vulnerable status (BirdLife International 2012).

Effects of human activity on populations

Ocellated Antbirds are demonstrated to be very sensitive to forest fragmentation. Studies with closely related species have shown that antbirds have an extreme aversion to crossing gap areas (Laurance et al. 2004), as well as a physical inability to fly long distances (Moore 2008). The birds’ large feeding range requirements also contribute to their sensitivity (Willis and Oniki 1978). A study on Barro Colorado Island in Panama tracked the extinction of Ocellated Antbird from the island. After the island was isolated in the early 1900’s by construction of the Panama Canal, these birds’ populations gradually declined. By 1970, the island’s population was totally extinct (Willis 1974).
