Researchers have shown that a plant can discriminate among its pollinators. The plant, Heliconia tortuosa, produced 5.7 times as much pollen when it was visited by particular species of hummingbirds than other species or insects.
The researchers suggest this ability enables the plant to maximize its reproductive strategy as the favoured hummingbirds travel greater distances, reducing the likelihood of the plant inbreeding.
