Hawaii's birds are going extinct. Their last hope could be millions of mosquitoes

Every week at the Maui airport, a small helicopter gets loaded with 250,000 passengers. They're male mosquitoes, key players in a strategy that could be the last, best hope for Hawaii's endangered birds.

"We got mosquitoes to drop," Christa Seidl of the Maui Forest Bird Recovery Project calls to the pilot. She wheels over a crate with several hundred cardboard tubes filled with mosquitoes. Soon, they’ll be airdropped into Maui's high-elevation forests, the last refuge for endangered birds.
