BirdLife species factsheet for Green-capped Tanager Green-capped Tanager Tangara meyerdeschauenseei is described as relatively common at three sites in the arid area at the headwaters of the río Inambari in Puno, south-east Peru. It is currently listed as Vulnerable under criterion D2 because it was thought to have a very small range, found in fewer than 6 locations. However, recent fieldwork reported that this species is also found in the Apolo area of northwestern Bolivia (Berg and Van Kleunen in litt. 2012). The majority of observations were made in dry, open scrubland and forest borders with an elevation of 1450-1700m, typical of Bolivian Andean Cerrado (Berg and Van Kleunen in litt. 2012), but one observation of this species was also made in humid Yungas forest close to Santa Cruz de Valle Ameno, Madidi National Park. This species was previously reported in this humid forest habitat at Tokoaque, Madidi National Park, in 2001 (Hennessey and Gomez 2003), but the presence of a population here was treated as unconfirmed. If this information is confirmed, and the Green-capped Tanager does also occur in Bolivia in a wider range of habitats than first thought, the population size and range of this species may be higher than previously believed (Berg and Van Kleunen in litt. 2012) and this species may no longer qualify as Vulnerable on the IUCN Red List. If it is not restricted to fewer than 6 locations, and its population is not continuing to decline, it would warrant downlisting to Near Threatened, approaching criterion D2 on the IUCN Red List, or possibly even Least Concern. Information is requested on this species’s likely population size, trends and distribution. Further information regarding its tolerance of habitat disturbance and habitat requirements is particularly welcome. Reference: Hennessey, A. B. and Gomez, M. I.
