Birds provide the perfect air-carrier for some seeds.
Seeds from fruits eaten by birds can travel many miles in this comfortable craft and survive the trip to settle in new lands. Animal dispersal Passionvine seedlings germinate in cow manure. Pigs, cows, goats and other animals eat fruits that carry the seeds of pest plants. The seeds survive within their digestive tracts and are dispersed as the animal roams in search of other food sources. Once released the seeds have a convenient source of nutrients and grow easily.
