Sparkling Violetear vs Andean Hillstar: common questions
Which hummingbird survives more extreme conditions?
The Andean hillstar does, foraging above 4,000 metres and entering deep nightly torpor to survive freezing temperatures, conditions far more extreme than the sparkling violetear typically encounters.
Which hummingbird is more aggressive?
The sparkling violetear is, known for vigorously defending flowering plants and feeders, a behaviour not specifically highlighted in the Andean hillstar.
Why is the Andean hillstar larger than many hummingbirds?
Its relatively large body size helps it retain heat more effectively at the extreme high-altitude elevations it occupies, an adaptation not needed by the more moderate-elevation sparkling violetear.
