Blue-chinned Barbet Eubucco glaucogularis



Justification

Justification of Red List Category

This species is suspected to have a small population, which is in slow decline due to habitat loss. It is therefore listed as Near Threatened.

Population justification
The global population size has not been quantified directly, but the species is described as 'uncommon' (Stotz et al. 1996). Congeners are known to occur at a density of 1-8 mature individuals/km2 (Eubucco richardsoni and E. tucinkae in Peru; Santini et al. 2018). About 10,000 km2 within the range is covered by forest (Global Forest Watch 2021); assuming that 50% is occupied by this species, the population may number 5,000-40,000 mature individuals. In view of its apparent rarity, the true population size may be closer to the lower end of the estimate.

The species is monotypic; therefore it is tentatively assessed as functioning as one subpopulation.

Trend justification
The population trend has not been assessed directly, but it is inferred that this strictly forest-dependent species is undergoing a decline due to the loss and degradation of forests within the range. Over the past ten years, tree cover within the range has been lost at a rate of 6% (Global Forest Watch 2021). Based on deforestation rates between 2016 and 2020 and extrapolating into the future, the rate of tree cover loss may increase to 8% over the next ten years (Global Forest Watch 2021). Given that the species is highly dependent on forest and potentially susceptible to fragmentation and edge-effects, the rate of population decline may be higher than the rate of forest loss and as such the species may be declining at up to 19% over ten years.

Distribution and population

Eubucco glaucogularis is endemic to Peru, ranging from east Huánuco to north Cuzco, where it is considered uncommon (del Hoyo et al. 2002).

Ecology

This species prefers submontane humid forest of 1,000-2,000 m; it also occurs in old secondary forest (del Hoyo et al. 2002).

Threats

The primary threat to this species is habitat loss, as forests are cleared for agricultural expansion (Bird et al. 2011).

Conservation actions

Conservation Actions Underway
None is known.

Conservation Actions Proposed
Quantify the population size. Assess the subpopulation structure. Monitor the population trend.
Expand the protected area network to effectively protect IBAs. Effectively resource and manage existing and new protected areas, utilising emerging opportunities to finance protected area management with the joint aims of reducing carbon emissions and maximizing biodiversity conservation. Conservation on private lands, through expanding market pressures for sound land management and preventing forest clearance on lands unsuitable for agriculture, is also essential (Soares-Filho et al. 2006).

Identification

16 cm. Small, multicoloured barbet. Generally with a red cap, and blue on the back of the head. The upperparts are green to blue-green. It has a yellow and red breast, with a belly streaked buff and green.
