Plants Blast Pollinating Passerine Birds with Pollen Clouds

Agnes Dellinger and Florian Etl present the complex bird pollination system of the neotropical treelet Axinaea. Foraging birds activate a bellows organ, which causes the ejection of pollen clouds onto the birds, resulting in pollination. The entire pollination process and details on the structure, composition, and functioning of the bellows organs are presented in this movie.
