Thrives at 10,000 feet in the Andes where most birds tap out. Electric cobalt and jet black, built for altitude.
- Populasi
- Global population size not quantified; historically described as fairly common (before taxonomic splits), current population trend decreasing due to ongoing Andean forest loss (~1.5% forest decline in range over past decade)
- Habitat
- Subtropical/tropical moist montane forest, dwarf (elfin) forest, secondary forest, forest edges, and shrubby vegetation near tree line; elevational range roughly 1,020-3,760 m (most commonly recorded 1,300-3,500 m)
- Fakta menarik
