Taxonomic note
Previously regarded as a subspecies of C. largipennis (HBW/BirdLife International 2018) but split following Lopes et al. (2017, 2020). Differs from C. l. largipennis by its longer ‘LTTs’ (light tail-tips) (effect size 2.39 for male LTT1; score 2); base of outer rectrices bright bronzy-green vs dark grey (1); totally different habitat (1); totally different voice, with the song a high tittering trill, quite unlike anything on Xeno-canto for largipennis (at least 4). For difference from C. calcirupicola, see that species. Monotypic.

Population justification: The population size is unknown, but it is naturally rare. The species occurs on several upland areas and is unlikely to disperse over large distances, so there are likely to be multiple isolated subpopulations.

Trend justification:

The species's range has been variously projected to contract by c.66-75% by 2045-2060 (Marini et al. 2009), or by over 99% by 2050 and 2070 (Hoffman et al. 2020), both relative to climatic conditions from up to 1990, as a result of climate change. The species's population is therefore inferred to be undergoing a continuing decline. The magnitude of loss over the next decade is highly uncertain; if the above projected changes occur at a constant rate, they may equate to a loss of 9-17% over ten years, or if an exponential decline occurs, a loss of 14-55% over ten years, but the timing and pattern of future reductions are poorly-known.
