Yellow-crowned Flowerpecker

The yellow-crowned flowerpecker was formally described in 1914 by the Australian-American ornithologist Richard Crittenden McGregor as Prionochilus anthonyi based on a specimen collected on Mount Polis, Province of Ifugao on the island of Luzon in the Philippines. McGregor chose the specific epithet to honour the American mining engineer and ornithologist Alfred Webster Anthony. Exhibits sexual dimorphism in which males have the eponymous yellow crown and vent while females are much more dull and have uniform olive color and does not the black upperparts It was formerly conspecific with the flame-crowned flowerpecker but differs with its yellow crown and vent and yellowish belly.

It inhabits tropical moist montane forest from 1,500 to 2,000 meters above sea level. The International Union for Conservation of Nature assessed this species in 2023 as Least-concern. Prior to this, it was assessed as near threatened with its population being estimated as 10,000 to 19,999 mature individuals. This species is uncommon throughout its range. The current assessment states that the population is supposedly stable. However, forest loss is a threat especially in its lower altitude limits which are more prone to legal and illegal logging, mining and conversion into farmland and road development. It is recommended to investigate potential threats and quantify more precisely the population size of the species. Protect areas of suitable habitat and safeguard against deforestation.
