In 1865, a physician brought Indian mynas to Hawaii to eat armyworms; the birds spread and can compete with native birds for nesting sites

In 1865, a German-born physician named William Hillebrand brought Indian mynas to Hawaii to combat an armyworm infestation, a pest damaging young sugarcane and grasses. The mynas, native to South Asia, were introduced by Hillebrand, who was living in Hawaii since 1850. At the time, the mynas were intended to be a simple pest-control tool, not a permanent fixture in the island's ecosystem.

However, the mynas proved to be more adaptable than anticipated, surviving on a diverse diet that included house scraps, fruits, grains, insects, and grubs. Their ability to thrive in diverse environments, as described by ornithologist E. L. Caum in 1933, has led to their widespread presence in Honolulu over the past 160 years. The mynas' extensive diet and adaptable nature have allowed them to outcompete native birds for nesting sites, a fact that has sparked ongoing debate since their arrival.

While it is clear that mynas have become a nuisance in some areas, the extent of their impact on native Hawaiian birds remains a topic of discussion. The story of the mynas serves as a cautionary tale about the potential long-term consequences of introducing foreign species to new environments without fully considering the potential outcomes.
