Justification:
This species qualifies as Vulnerable because it has a very small range, within which it is known with certainty from just four locations. However, its ecology and habitat requirements remain poorly understood, and if its habitat or population are shown to be declining, it would merit uplisting to Endangered (Collar et al. 1992).

Geographic Range
[top]
| Range Description: |
Tangara meyerdeschauenseei is relatively common at three sites in the arid area at the headwaters of the río Inambari in Puno, south-east Peru and in the Apolo area of northwestern Bolivia (Berg and Van Kleunen 2012). It has also been reported at Tokoaque, Madidi National Park, west Bolivia (Hennessey and Gomez 2003), although the humid forest habitat here is highly atypical for this species group and the presence of a population here is best treated as unconfirmed. Published sightings in dry forest along the río Machariapo within Madidi National Park (Parker and Bailey 1991), were later retracted (Hennessey and Gomez 2003).

| Population: |
The species is described as fairly common to locally common; its population is placed in the band 1,000-2,499 individuals, equating to 667-1,666 mature individuals, rounded here to 600-1,700 mature individuals.

Habitat and Ecology
[top]
| Habitat and Ecology: |
The semi-arid habitats in the area of the Peruvian records have already been heavily modified, with the original habitat types unknown (Hennessey and Gomez 2003). The recent Bolivian report was from humid Yungas forest, and seasonal movements between habitats have been postulated (Hennessey and Gomez 2003). Records are from between 1,750 and 2,200 m, but it probably ranges beyond these limits. It is usually found singly, in pairs or groups of three or four (Naoki 2003), foraging in fruiting trees and probably taking fallen fruit from the ground. It has been recorded taking a variety of fruit and arthropods (Naoki 2003) and probably breeds around November.

| Systems: |
Terrestrial |
| Major Threat(s): |
Its usage of semi-open and edge habitats suggests that it may be relatively tolerant of habitat disturbance. However, recent suggestions that it prefers humid forest, or undergoes seasonal movements, need further investigation, and it cannot at present be considered secure.

| Conservation Actions: |
Conservation Actions Underway
The recent Bolivian report is from within Madidi National Park (Hennessey and Gomez 2003).
Conservation Actions Proposed
Assess its range and population size. Survey the biota of valleys in the río Machariapo area (Parker and Bailey 1991). Research its ecology and habitat requirements. Conduct research to clarify pertinent threats. Carry out surveys to clarify its status in Bolivia. Grant protected status to additional occupied sites and areas of suitable habitat.
