This method has an advantage over the eaten seed, as the seed coat does not have to be reinforced to withstand the bird's stomach. Also the eaten part, the fruit, can be smaller and so can be eaten by a wider range of birds. The disadvantage is in the fact that the seed is dropped to the ground soon after removal from the plant, and would not travel the distances that a seed might if it spent an hour or two inside a bird. Other seeds are eaten by birds as the bird digests and utilises the fleshy covering. The fleshy fruits of Eremophila debilis .
Some birds have a nomadic lifestyle, following fruiting trees.
As a method of seed dispersal between rainforest patches, these birds are ideal. They spend little time out of rainforests and travel extensively. Seeds of many other plants will not germinate unless eaten by birds. Perhaps we can overcome these germination problems by feeding the seeds to turkeys. To help the chances of staying alive while passing through the bird's digestive tract, many seeds have rapid trips.
