Population justification: The global population size has not been quantified, but the species is described as uncommon to rare (Eaton et al. 2021). However, an accurate assessment on the status of this species is hampered by its identification, particularly due to confusion with A. rhodogaster, but occasionally A. trinotata and Lophospiza griseiceps. Much of its range is also poorly known.
Trend justification: Given this species's occurrence in montane forests, encroachment by agriculture and timber extraction has been minimal in its range. Global Forest Watch (2021) data, using Hansen et al. (2013) methods and data disclosed therein, suggest that forest loss in its range has been minimal (0.2% per annum) and is not necessarily above the rate of natural flux. The population is therefore suspected to be stable, but may decline if forest loss begins to encroach on higher elevation forest.
