This discussion was first published as part of the 2016 Red List update. At the time a decision regarding its status was pended, but to enable potential reassessment of this species as part of the 2018 Red List update this post remains open and the date of posting has been updated.
Campo Miner occurs within interior south-central Brazil (from São Paulo, where it is now considered extinct, north to Minas Gerais, Goiás and Mato Grosso), north-east Bolivia (north-east Santa Cruz in the Serranía de Huanchaca), and a specimen was collected in Paraguay in 1938 (J. M. Bates in litt. 1999, Ridgely and Tudor 1994, Sick 1993). Although it may be locally common in places, it is generally uncommon and has declined as large areas of cerrado are converted for agriculture, cattle-ranching and plantations. It has therefore been listed as Vulnerable under Criteria A2c+3c+4c.
In the Brazilian Red List assessment for birds (MMA 2014) this species is listed as Endangered under Criterion B2ab (ii, iii), based on its fragmented distribution, a continuing decline caused by wildfires, and a calculated area of occupancy of 132km2. The species’s assessment on the Brazilian Red List can be accessed here.
Up-to-date information is requested on the species’s area of occurrence, level of fragmentation and population trend. Confirmation that the area of occurrence is smaller than 500 km2 and that the population is severely fragmented and declining would likely qualify the species for uplisting to Endangered under Criterion B2ab. Comments on the proposed uplisting are welcome.
