The pale-billed parrotbill (Chleuasicus atrosuperciliaris)

The pale-billed parrotbill (Chleuasicus atrosuperciliaris), also known as the black-browed parrotbill or lesser rufous-headed parrotbill, is a species of parrotbill in the family Paradoxornithidae.

This adorable small parrotbill with an oversized head is a common companion of White-hooded Babblers in mixed flocks. Brown above and white below with a bright orange head and small but prominent black brow; compare with larger Rufous-headed Parrotbill, which doesn’t have a brow mark. Found in foothill and submontane forests and forest edges, particularly in dense bamboo stands. Vocalizations include rattling trills and whistled notes.

This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
