Taxonomy

Taxonomic note
Ceyx melanurus and C. mindanensis (del Hoyo and Collar 2014) were previously lumped as C. melanurus following Sibley and Monroe (1990, 1993).

Population justification: Poorly known. Described by Allen (2020) as local and uncommon, and the paucity of observations of this species in citizen science data (eBird 2024) would ostensibly suggest that it is a rare species. However, Ceyx are cryptic and have low detectability, with mist-netting proving a far more reliable indicator of their true abundance than walked transects. During mist-netting on Alabat, Ceyx melanurus was the third most commonly caught species (Gomez et al. 2009). Its habitat tolerances are not well understood, but almost all Ceyx are plastic in habitat use, and C. mindanensis, with which this species was formerly conspecific, is apparently highly tolerant of forest modification (de Leon et al. 2018). While its population size is therefore recorded as unknown, given its range covers nearly 80,000 km2, even if only a small percentage of this is occupied, the global population size is unlikely to be small.

Trend justification: The only plausible threat to this species is habitat loss and degradation. Although previously often regarded as dependent on virgin forest, it tolerates open forest and secondary growth, as do most Ceyx species (de Leon et al. 2018, Allen 2020, eBird 2024). Global Forest Watch (2024, using data from Hansen et al. [2013] and methods disclosed therein) indicates that over the past 10 years, approximately 5-8% of forest canopy cover has been lost, but in many places this has been replaced with plantations, which this species may inhabit, or may have overgrown. Accordingly, this value may not accurately reflect the population trend of this species, which is set to ongoing declines of 0-10% to account for considerable uncertainty. Nonetheless, it seems unlikely that this species is declining more rapidly.
