LC
Straight-billed Hermit Phaethornis bourcieri



Justification

Justification of Red List category
This species has an extremely 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). The population trend appears to be stable, and hence the species does not 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.

Population justification
The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996).

Trend justification

The species is suspected to be stable in the absence of evidence for any declines or substantial threats.

Distribution and population

This species occurs through north-eastern Peru, eastern Ecuador, south-eastern Colombia, southern Venezuela, Guyana, Suriname, French Guiana and northern Brazil (Hinkelmann et al. 2019).

Ecology

The species usually inhabits lowland terra firma rainforest and semi-deciduous or pre-montane forest (up to 1600m), occasionally also forest edge, bamboo thickets, dense shrubbery, várzea forest, second growth or plantations (Hinkelmann et al. 2019).

Identification

A medium-sized hermit, of 12-14cm and 3.5-5g. Olive-green upperparts, brownish to greyish underparts. Distinctive straight bill, dark brown on top, more orange below (Hinkelmann et al. 2019).
