Taxonomy

Taxonomic note

Eight species, Hypsipetes affinis, H. longirostris, H. mysticalis, H. harterti, H. aureus, H. platenae, H. chloris and H. lucasi have been moved from the genus Thapsinllas (del Hoyo and Collar 2016) following a comprehensive phylogeny of the bulbuls (Shakya and Sheldon 2017). All were previously lumped as Alophoixus affinis following Sibley and Monroe (1990, 1993).

Population justification: The global population size has not been quantified, but the species has been been described as common in its range in a range of habitats including heavily degraded forests and mixed plantations (Eaton et al. 2021). While tree cover is estimated to have declined by 15.6% within its mapped range over the past 10 years (Global Forest Watch 2022, using Hansen et al. [2013] data and methods disclosed therein), this species' habitat tolerances mean the population trend overall is thought to be stable.
