Data Zone
Justification of Red List category
This species is tolerant of habitat modification, but forest loss has been extensive across much of its range. It is therefore suspected to be undergoing a moderately rapid population decline and has been classified as Near Threatened.
Population justification
The global population size has not been quantified, but the species is reported to be fairly common to common in most of its range (Wells 1999, del Hoyo et al. 2002).
Trend justification
Remote sensing data (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein) indicate that forest cover loss in this species range has been 25-30% over the past three generations (11.1 years; Bird et al. 2020). Although this species is suspected to occur at higher densities in primary and selectively logged forest than plantations, it does occur in the latter (Wells 1999) such that the rate of decline is suspected to be no higher than that of forest loss, and so is suspected to be 20-29% over three generations. The declines are suspected to continue at a similar rate into the future.
C. hayii is found from southernmost Tenasserim, Myanmar (where it is rare); south Thailand from about 10o 30' N (including Phuket); peninsula Malaysia; and Sumatra, Indonesia (Short and Horne 2001, del Hoyo et al. 2002). It formerly occurred in Singapore (Short and Horne 2001).
It inhabits lowland primary forest and lower hill forest, swamp forest and also human-modified habitats such as cacao plantations, scrub forest and isolated fruiting trees in cut-over forest (Short and Horne 2001). The species primarily eats fruit, but also takes insects including foraging in arboreal ant and termite nests (Short and Horne 2001). Often 2-3 pairs nest in the same tree stump; cavities are excavated in both living and dead trees and stumps (Short and Horne 2001).
It appears relatively insensitive to selective logging, and can remain relatively common even in recently logged forests (e.g. Panti forest reserve, Johor) or 20-year old logged forests in Tasik Kenyir, Terengganu (D. L. Yong in litt. 2014). Elsewhere in Peninsular Malaysia, Peh et al. (2005, 2006) also found the species in rubber plantations, mixed agriculture landscapes and secondary forests. Nevertheless, it presumably occurs at lower densities in logged forest, and the extensive habitat conversion and degradation that have taken place throughout its range (in particular for logging and conversion for oil palm) are thought to be driving declines.
Conservation and research actions underway
No targeted actions are known, but the species presumably occurs in a number of protected areas.
Conservation and research actions proposed
Quantify the population size. Determine its precise ecological requirements and its ability to persist in degraded and fragmented habitats. Ensure the effective protection of existing protected areas in which it occurs.
17.5cm. A relatively small, brown barbet with a heavy bill and short tail. The throat and breast are buffy with a slight yellow tinge from breast to belly, with the lower belly and vent white. The bill is black in the male and horn-brown in the female. Similar spp. C. fuliginosus has rufous tones on the throat and breast. Voice. Noisy, sibilant "pseeee" calls given in series frequently as groups forage together.
