Ash-bellied Hermit Phaethornis major

Current view: Text account

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 is estimated 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 population size has not been quantified.

Trend justification
The population trend has not been quantified, but the species is tentatively assessed as being stable.

Distribution and population

Phaethornis major is restricted to the Tapajós area of the Amazon basin in Brazil (Araújo-Silva et al. 2017).

Ecology

The species usually inhabits lowland terra firma rainforest and semi-deciduous or pre-montane forest (up to 1,600 m), occasionally also forest edge, bamboo thickets, dense shrubbery, várzea forest, second growth or plantations (Hinkelmann et al. 2019).

Threats

The threats to this species are unknown.

Identification

Olive-green upperparts with greyish underparts. A distinctive straight bill. Larger size than Phaethornis bourcieri (Hinkelmann et al. 2019).
