Population justification: The population size of E. kochi has not been estimated. It is described as 'scarce and local' by Allen (2020) and eBird (2023) corroborate this description, with the species evidently being detected only infrequently; nonetheless, unless vocal, birds are likely to prove elusive and it is likely to be more numerous than records alone suggest. In its range, there is a large area of habitat, amounting to nearly 25,000 km2 (Global Forest Watch 2023). Even if only a small percentage of this forest is occupied, the global population size is unlikely to be especially small.

Trend justification: In the absence of empirical population trend data, remote-sensed forest cover loss data is used as a proxy for this forest-dependent species. In the past three generations (13 years: 2009-2022), forest cover in this species' range reduced by c. 2% (Global Forest Watch 2023, based on data from Hansen et al. 2013 and methods disclosed therein). This does not account for habitat degradation (via selective logging etc.), which may have some impact on this species, although (like other Erythropitta) it is suspected of being tolerant of selectively logged and degraded forest (Allen 2020). No other threats beyond forest loss are known. The population is therefore suspected to be declining only very slowly, set here at a continuing rate of 1-9%.
