Range DescriptionThis species has been recently described based upon three specimens collected at a Universidad de la Salle retreat called La Lana, vereda Llano de Ovejas, near San Pedro de los Milagros, Antioquia, Colombia. Two of the specimens are undated, but the third was collected in 1971 (Donegan 2007). Fieldwork in 2007 and 2008 (P. Salaman in litt. 2008) failed to detect the species close to the labelled type locality; there are no known extant populations. While there is hope that it persists at the type locality, if it does it must be rare. Rapid assessment surveys in the Northern Andes have typically recorded over 90% of resident birds at survey sites, and fieldwork at La Lana did record two other Atlapetes species, both of which were also recognised by local people; no-one recognised photographs of the A. blancae specimens. It is plausible that the species occurs nearby, but not at the type locality; several specimens of A. schistaceus are labelled from La Lana, but the species was only recorded away from the site where it was rare at 2,800 m. Alternatively A. blancae may be locally extinct on the Llano de Ovejas given the extent of recent deforestation and the presence of A. latinuchus in all secondary and forest edge habitats. An assessment of old collections from La Lana reveals that the only other missing species were transient migrants and waterbirds (Donegan et al. 2009). Atlapetes can be abundant in scrub bordering natural marshlands in the Colombian Andes, and most wetlands in this region have been drained or replaced with reservoirs (Donegan et al. 2009).
