Seeds scattered by birds Birds eat the fruit and discharge the indigestible seeds. /, thistle ; ^, mistletoe; s, bird cherry; 4, red-osier dogwood selves and to invade new regions more successfully than those that depend upon other agencies for scattering the new plants. Many plants have their seeds distributed by currents of water, — streams of various sizes, or ocean currents, or wind currents acting on the water. Seed plants that grow in swamps or ponds are commonly dependent upon water currents for the dispersal of their seeds. But it seems that many seeds are also spoiled by the water. The coconut, for example, which is often cited as a plant that invades ocean islands by being carried over the sea, is reall}- killed by the salt water.
