The first expedition departed Honolulu on April 4, 1923 and returned on May 4. The team visited the island of Laysan, Pearl and Hermes Atoll, Midway Atoll, and Kure Atoll. When they spent a month on Laysan studying the endemic Laysan honeycreeper, a violent and sudden storm ravaged the island. After the storm, the crew concluded that the last three specimens of the honeycreeper had been killed.
