The island of Guam in the South Pacific had no natural predators until the early 1950s, when the brown tree snake was accidentally introduced by either ships or aircraft shortly after the Second World War. Scientists studying the effects of this invasive species surveyed five different native bird species in an area of northern Guam that the brown snake had recently invaded. The graph shows the population data of the five different native bird species from 1976 to 1998.

Which of the following best describes the data and explains the effect of the arrival of the brown tree snake on Guam’s native bird species?
