The White-sided Hillstar is a distinctive hummingbird of the high Chilean and Argentinian Andes. Males possess an iridescent green throat and a brilliant white stripe on their flanks, contrasting with a rufous belly.
Where to spot
Found in the high Andes of central Chile and western Argentina, primarily inhabiting puna and high-altitude grasslands, rocky slopes, and shrublands, typically between 3,000 to 5,000 meters.
How to spot
Look for its striking white flank stripe, a key identification feature, especially on males. It often perches on rocks or low vegetation, and feeds on high-altitude flowering plants. Be prepared for strong winds and cold temperatures at these elevations.
When to spot
Active during daylight hours, particularly on sunny mornings. Observable year-round in its habitat, though access may be limited by snow in winter at higher elevations.
This species often bathes in melting snow or frost, a behavior rarely observed in other hummingbirds, likely due to its extreme high-altitude, cold habitat which presents unique water sources.
