Blue-rumped Manakin Lepidothrix isidorei


Justification of Red List Category

Based on a model of future deforestation in the Amazon basin, it is suspected that the population of this species will decline by 25-30% over the next three generations, and it has therefore been uplisted to Near Threatened.

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

Trend justification
This species is suspected to lose 29.1-30.5% of suitable habitat within its distribution over three generations (12 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). It is therefore suspected to decline by a rate approaching 30% over three generations.

Distribution and population

Lepidothrix isidorei has a disjunct range, occurring on the eastern slopes of the Andes in north-west South America (del Hoyo et al. 2004). The nominate subspecies isidorei occurs rarely in Boyacá, Meta and Cauca departments, Colombia. It is more common in east Ecuador, especially in the río Bombuscaro area of Podocarpus National Park (del Hoyo et al. 2004, Restall et al. 2006). Subspecies leucopygia is a rare endemic to north Peru, occurring in San Martín and northern Huánuco (del Hoyo et al. 2004).


This is a humid forest species of the Andean foothills, occurring from 500-1,700 m elevation (del Hoyo et al. 2004).


The primary threat to this species is accelerating deforestation in the Amazon basin as land is cleared for cattle ranching and soy production, facilitated by expansion of the road network (Soares-Filho et al. 2006, Bird et al. 2011).

Conservation actions

Conservation Actions Underway
None is known.

Conservation Actions Proposed

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).


7-8 cm. Small, dimorphic manakin. Male has a shiny white cap, with an azure rump and uppertail-coverts; the rest of the plumage is black. Female in contrast is mostly green, with a yellowish grey abdomen.
