Geographic Range [top]

Range Description:	Heliangelus zusii is known from a single trade-skin purchased in 1909 in Bogotá, and speculated to have been collected on the East Andes or possibly the Central Andes of Colombia, within a few hundred kilometres of the capital. However, some "Bogotá" specimens came from as far away as Ecuador¹. Since no other specimen is known, it is assumed to be (or have been) a species of restricted range. However, the validity of this taxon is sometimes questioned^e.g.1. Much habitat in the Colombian East and Central Andes has been extensively degraded, particularly within the lower limits of this species's presumed elevational range. However, its probable habitat preferences suggest that it is not inconceivable that a remnant population may persist. Although previously treated as Critical, a recent re-evaluation of poorly known, possibly extinct Critical species and Data Deficient species has indicated that this taxon is best treated as Data Deficient at present.
