The little gray-and-white bird used to be a common backyard visitor across the island, Marcil said. But the introduction of avian malaria to the island began to devastate akikiki populations. Birds that lived at higher, colder elevations were safe for a while. But a warming climate on the island allowed mosquitoes to reach higher into the mountains where the malarial parasite has killed virtually every surviving bird.

Growing up in Hawaii, Marcil said the akikiki often went unnoticed because of its drab colors and small size, flitting about the treetops and calling in a high-pitched peep.

“What’s really devastating is the akikiki once was as common as a pigeon on Kauai,” Marcil said.

PBS Hawaii will host a special online screening 6 p.m. Tuesday of Marcil's film “When Silence Becomes the Song.” Registration is required.

The digital screening will include a live Q&A with Marcil and the director of the recovery project, Cali Crampton.

PBS Hawaii featured the film on its November program guide cover.

Exactly how avian malaria arrived in Hawaii is a mystery. People could have introduced it through domestic fowl. Or far-flying seabirds might have introduced it to the island.

But once there, it quickly began decimating birds that had no natural defenses.

Marcil followed researchers as they searched the forest and tried to get any birds to respond to audio playbacks of their calls. But wherever they went, no birds called back.

“You could hear the wind and nothing else. It was disheartening,” she said.

Researchers were hopeful they could collect birds from the last known nest.

But the day they were to depart for the plateau, a storm struck the island. When researchers got there, the nest was abandoned and the hatchlings had died.

“It’s devastating,” Marcil said. “You see thousands of years of evolution dwindle to nothing just like that.”
