The roof of some mistletoe flowers releases pollen when the weight of a landing bird triggers the explosive opening of a storage chamber.
"Another species in the same family [of tropical mistletoe] stores its pollen in the roof of its flower. As a bird lands, its weight triggers the chamber so that it opens explosively and showers pollen all over the bird's forehead." (Attenborough 1995:117)
