This discussion was first published as part of the 2010 Red List update, but remains open for comment to enable reassessment in 2013. Link to current BirdLife species factsheet for Glow-throated Hummingbird Glow-throated Hummingbird Selasphorus ardens is currently listed as Vulnerable on the IUCN Red List because although known from fewer than six locations within a tiny range (west and central Panama), and having a very small estimated population the population structure did not meet the thresholds for listing in a higher category of threat and the known localities were thought to be largely unaffected by human activities. However, G. Angehr in litt. (2008) has outlined that this is no-longer the case: deforestation for subsistence agriculture is severely affecting the core of the species’s range in the area of Cerro Santiago, where deforestation has reached and crossed the continental divide. This worrying news suggests that the species now warrants uplisting to Endangered owing to its very small range in the Serranía de Tabasará (eastern Chiriquí and Veraguas provinces) and possibly the highlands of Azuero Peninsula, Panama with continuing declines in the extent and quality of habitat and the number of individuals at known localities. Comments on this proposed uplisting are welcomed. Selasphorus ardens: subir a En Peligro? Selasphorus ardens se encuentra categorizada como Vulnerable en la lista roja. Aunque solo se conoce de < 6 localidades dentro de un área de distribución muy pequeña, y con una población muy pequeña, la estructura de la población no le permitió ser clasificada en una categoría de amenaza mayor. Además, no se creía que las localidades conocidas estaban muy afectadas por actividad humana. Sin embargo, G. Angehr in litt (2008) ha señalado que esto ya no es el caso. La deforestación está afectando severamente el área nuclear del área de distribución de la especie en el área de Cerro Santiago, donde la deforestación ha llegado a, y ha cruzado, la divisoria continental. Estas noticias preocupantes, sugieren que la especie debe subir a En Peligro, debido a su área de distribución muy pequeña en Serranía de Tabasará (este de Chiriquí y Veraguas), y posiblemente en las tierras altas de la península de Azuero, Panama. También hay disminución en la extensión y calidad de hábitat y en el número de individuos registrados en las localidades conocidas. Comentarios bienvenidos.
