Useful to know

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.
