The forest of the Sangal Valley, in Cajamarca, harbor the largest population of Gray-bellied comet (Taphrolesbia griseiventris), endemic and endangered, restricted to the valleys of the western slope of the Andes in northern Peru. This little-known bird inhabits relict forests and bushes near streams where it feeds mainly on flowers of babilla (Delostoma integrifolium) and huarangay (Tecoma sambucifolia). Sangal lands are rich in ornamental flower production and agricultural crops, so the expansion of these activities led this species in serious threat. As they are not commercially important species, the babillas and huarangays are replaced by no-native trees as fences, reducing the supply of food to hummingbirds. One of the ways to "clean" the areas before starting the crops is to burn the vegetation, so that, after a large fire went out of control in September 2018, more than 80% of the habitat of this species was lost.
