MAKAWAO, Hawaii. (AP) — Five Hawaiian crows on Wednesday were released on Maui for the first time as part of an ongoing effort to return the species to its home, conservationists said.

The Hawaiian crows, or alala, were last found on Hawaii’s Big Island, but they went extinct in the wild in 2002, officials with the San Diego Zoo Wildlife Alliance said in a statement. The birds, described as intelligent and charismatic, are the last survivor of all the Hawaiian crow species. Habitat loss, predation and disease by introduced species are threats, among other factors.

“The translocation of alala to Maui is a monumental step forward in conserving the species and a testament to the importance of partnership in reversing biodiversity loss,” said Megan Owen, Ph.D., vice president of conservation science at San Diego Zoo Wildlife Alliance.
