Why are hummingbirds not allowed in Hawaii?
Why are hummingbirds not allowed in Hawaii? It was the pineapple industry that kept hummingbirds out of Hawaii. Hummingbirds are pollinators of pineapple. If pineapple gets pollinated, it sets seed. The very hard seeds get in the way of people eating pineapple, so the plantation owners led to hummingbirds being banned and quarantined.
Why has Hawaii lost so many birds?
Remaining birds such as the 'Akikiki, 'I'iwi, and Kiwikiu face multiple threats, ranging from loss of their feeding and nesting areas to direct predation by invasive species. Mosquito-borne diseases have further decimated populations of Hawaiian birds.
