Distribution in the Americas

The site where the holotype of Bogota Sunangel was collected is unknown, and so there is tremendous uncertainty regarding the range of this species. Graves (1993) speculated that the holotype was collected in the Eastern Cordillera of the Andes of Colombia, or possibly in the Central Cordillera. It now is known, however, that Heliangelus zusii is closely related to the sylphs (Aglaiocercus), which occur in the Andes from Venezuela south to Bolivia, and to Gray-bellied Comet (Taphrolesbia griseiventris), which is restricted to the Andes of northern Peru; consequently, the distribution of Bogota Sunangel presumably falls anywhere between Venezuela and northern Peru (Kirchman et al. 2010). Graves (1993) pointed out that the fact that it is known from only a single specimen suggests that Bogota Sunangel has, or had, a very restricted geographic distribution, and that its original distribution may already be deforested.

Distribution outside the Americas

Endemic to the Americas.

Habitat

Bogota Sunangel is not known in life, and so its habitat preferences are undescribed. It is most closely related to Gray-bellied Comet (Taphrolesbia griseiventris), which occupies arid montane scrub in intermontane valleys, and sylphs (Agliaocercus), which occur in humid montane forest (Kirchman et al. 2010).
