Archived 2010-2011 topics: Golden-crowned Manakin (Lepidothrix vilasboasi): uplist to Endangered?

Link to current BirdLife species factsheet for Golden-crowned Manakin

Golden-crowned Manakin Lepidothrix vilasboasi is known only from the state of Pará, Brazil, where it is currently known from fewer than five localities, and has an estimated Extent of Occurrence of 160 km2. It is currently classified as Vulnerable on the IUCN Red List. Forest at the 2002 locality has already been destroyed and clearance is increasing rapidly in response to the increasing demand for cattle pasture from colonists, with the Novo Progresso area currently experiencing one of the highest rates of deforestation in the Amazon. It would therefore appear to qualify as Endangered under criterion B1a+b, having an EOO <5,000 km2, known to exist at no more than five locations and undergoing continuing decline in area, extent and/or quality of habitat. Comments on this proposed reclassification are welcomed.

  1. The species has a much larger range than the estimate above, and has been collected at several new localities recently – its occurs from the type locality in the Cururu in SW Pará, east to the west bank of the Rio Jamanxim near Novo Progresso and north at least to the Parque Nacional do Jamanxim (the eastern boundary is likely the Tapajós). Although there is likely to be substantial forest loss and perturbation in this interfluvium, one of its sister species – Lepidothrix iris is quite tolerant of logged and burnt forest around Santarem, PA, so long as it is not further exposed to area effects – most manakins are quite area-sensitive (i.e. absent from small fragments) but tolerant of disturbed and secondary forest. Thus the magnitude of the threat depends on market forces and whether large areas will be turned over to soya production once the BR163 is paved (worse case scenario) or whether the increased access potential simply results in a higher incidence of selective logging (more likely and much less threatening), Given that this species exists in several large existing PAs, is quite common within its admittedly restricted range and is likely quite tolerant to forest perturbation I wouldn’t recommend changing its status.
