Population justification: The global population size has not been quantified, but the species is described as fairly common to common, particularly in Guyana and French Guiana (del Hoyo et al. 2003).

Trend justification: The population of Guianan Antwarbler was suspected to be in decline by 20-25% over the next three generations based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). However, this analysis has since been repeated using more recent data on forest loss within the range (Tracewski et al. 2016). Tracewski et al. (2016) measured the forest loss within the species’s range between 2000 and 2012 as c. 7,645 km². This roughly equates to a rate of forest loss of 1% over three generations (14.4 years). As the species seems to tolerate habitat degradation, it may not be as severely affected by deforestation as previously feared. Therefore, the population is tentatively assessed as stable.
