Typical Environment
Restricted to Robinson Crusoe Island, it uses native forests, shrublands, ravines, and human-influenced areas near the settlement of San Juan Bautista. It prefers flowering native vegetation but also visits introduced ornamentals in gardens. The species forages along forest edges and in sheltered valleys where nectar sources are abundant. Breeding territories are often centered on dense patches of flowering shrubs and trees.

The Juan Fernández firecrown is a critically endangered hummingbird found only on Isla Róbinson Crusoe, Chile. Males are strikingly cinnamon-rufous with a fiery iridescent crown, while females are mostly green above with pale underparts, making the species highly sexually dimorphic. Habitat loss, invasive species, and competition for nectar threaten its survival. Conservation efforts focus on habitat restoration and controlling invasive plants and predators.
