The Sensory Ecology of Pollination in Hummingbirds
Quick fact
Hummingbirds are tetrachromats, seeing ultraviolet light, which allows them to distinguish flowers that look identical to human eyes but have UV patterns that guide them to the nectar.
Why this is interesting
You've seen them zip from flower to flower, but have you ever wondered what a hummingbird's world actually looks and tastes like? It's tuned to a reality that's completely invisible to us.
