Population justification: The global population size has not been quantified, but this species is described as uncommon. However, since its easily-overheard song was first recorded in 2004 (Verea 2004), it has been seen regularly at several different localities within Yurubí, Macarae, Henri Pittier and El Ávila National Parks (Verea 2004, C. J. Sharpe in litt. 2011). During surveys in suitable habitat, it was found to be common, comprising 2.4-3.5% of the bird community and being recorded in 80-83% of surveys (Verea 2004).The subpopulation structure has not been assessed; however its strict habitat requirements and territorial behaviour (Verea and Greeney 2020) and the spatial spread of records (per eBird 2021) suggest that it forms several disjunct subpopulations.
Trend justification: Data on population trends are lacking. The species is suspected to be declining slowly, owing to habitat loss in parts of its range through logging of forests for agriculture and fires (C. Verea in litt. 2020; Verea and Greeney 2020). As the species regularly uses secondary growth (Verea and Greeney 2020) declines are difficult to quantify, but they are not thought to exceed 10% over ten years.
