After 40 years without any records this species has been rediscovered, with records from several new locations. It has a very small known range, within which habitat loss is continuing, and is therefore listed as Endangered, but if it is found to be more widespread and proves to be tolerant of some habitat degradation it is likely to become eligible for downlisting.

14.5 cm. Smart, chestnut-and-black flowerpiercer. Black with blue shoulder patch and rufous-chestnut lower breast and belly. Similar spp. Black-throated Flowerpiercer D. brunneiventris is more extensively rufous below, with black limited to small throat patch, and greyish flanks and shoulder. Voice A house sparrow-like but higher pitched chirrup, and complex, hig-pitched vocalisations similar to those of other flowerpiercers.
It occurs near the timberline at elevations of 3,000-3,800 m in semi-humid/humid montane scrub and elfin forest edge, apparently ranging only a few metres or tens of metres below the páramo edge (Moynihan 1979, Ridgely and Tudor 1989, Fjeldså and Krabbe 1990, Parker et al. 1996). It favours Polylepis spp. with other small trees such as Escallonia or Baccharis. (O. Cortes in litt. 2011). Like most members of the genus, however, it does seem able to tolerate some habitat degradation and its population density is fairly high (Flórez et al. 2004). An apparent competitor is Black-throated Flowerpiercer D. brunneiventris, territories of the two species being mutually exclusive in the páramo at Frontino (Moynihan 1979).
The species has been recorded in Paramillo and Munchique National Parks, Reserva Mesenia-Paramillo and Tatama National Park (P. G. W. Salaman in litt. 1999, O. Cortes in litt. 2011).
Conservation Actions Proposed
Determine the population size and trends at the sites with recent records. Survey the high peaks of the West Andes to determine the true extent of the range and overall population size of this species. Support, finance and enforce better conservation measures for the two national parks. Manage protected páramos by increasing the amount of time between fires (Koenen and Koenen 2000). Extend Las Orquídeas National Park into the páramo zone (Flórez et al. 2004).
