Cloud-forest Pygmy-owl Glaucidium nubicola occurs on the west slope of the west Andes of central and south Colombia and north Ecuador. It has been recorded at few locations, of which at least one has been completely deforested since 1987. The population size is preliminarily estimated to fall into the band 2,500-9,999 individuals. This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.
It is currently listed as Vulnerable under criterion B1ab(i,ii,iii,iv,v) based on a small range (<20,000 km2) and a continuing population decline owing to on-going habitat destruction and fragmentation. However, recent information suggests that this species may have a smaller range than was previously thought. Freile and Castro (in litt. 2012) state that the current Extent of Occurrence (EOO) of the Cloud-forest Pygmy-owl is less than 5,000 km2 (approximately 2,570 km2) and can be considered fragmented and in continuous decline. Protection is also rather low, with no records from large protected areas in Ecuador. If this information is confirmed, and the range is considered to be severely fragmented, this species would warrant uplisting to Endangered under criterion B1ab(i,ii,iii,iv,v) of the IUCN Red List.
Information is requested on the population size, trends and distribution of this species, the extent to which its range is fragmented, and comments on the proposed uplisting are welcome.
