The seeds of Japanese barberry fruits pass through birds' intestinal tracts and germinate easily the next spring, helping to make this shrub an invasive species in some states. When shopping for bird-friendly berry bushes, choose those that won't contribute to an invasion of more such bushes the next spring.
