Taxonomic note

Dicaeum anthonyi and D. kampalili (del Hoyo and Collar 2016) were previously lumped as D. anthonyi following Sibley and Monroe (1990, 1993).

Population justification: The population size has not been quantified but it is typically described as uncommon (Dickinson et al. 1991, Allen 2020). Compared to other species in its range, D. anthonyi appears to be encountered comparatively rarely (eBird 2022), although it may be commoner at elevations not readily accessible. Poulsen (1995) encountered only one individual of this species, despite extensive fieldwork March–May 1991 and March–May 1992, although most of their study sites were far below the typical elevation of this species and their one encounter (at 1,050 m) was probably at its lowest end. In total, c.5,000 km of forest lies in its range and this is unchanged since 2000 (per Global Forest Watch 2022). Although no density is available for this species (using those of congeners is not considered appropriate given its apparent scarcity), the total number is very unlikely to be smaller than 10,000 mature individuals.

Trend justification: In the absence of acting threats, the population trend is thought to be stable. D. anthonyi inhabits remote mossy forest in Luzon's highlands where forest cover loss has been minimal, equivalent to <1% between 2000 and 2021 (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein). While these data do not take degradation into account, this species is tolerant of forest edge (Cheke et al. 2020) and, like other Dicaeum, is unlikely to need pristine forest. No other threats are known or expected.
